Finding Someone Who Lives Aboard a Boat
Somebody who lives on the water usually leaves no deed, no tax roll entry and no lease in their own name. The hull under them, though, is documented, numbered, titled, insured and rented a berth, and each of those records was created by a form that asked for an address. Work the vessel and the person follows. This page shows exactly which record holds which address, what the public Coast Guard search really returns, and why a marina mailbox proves less than it looks like it proves.
The Short Version
Find the boat, then find the paperwork the boat generates. A vessel is either federally documented with the Coast Guard or registered and titled by a state, and the two are mutually exclusive, so establishing which one you are dealing with cuts the work in half right away. The free public federal search will confirm the vessel and tell you nothing about the owner — it returns eight columns and not one of them is a name or an address. Ownership comes from an Abstract of Title, which the regulations let any person order. State registration is where most recreational boats actually live, held by a motor-vehicle department in some states and a wildlife agency in others, with sharply different privacy rules attached. Treat every address you recover as a claim to be tested, not a destination, because a liveaboard’s paperwork address is very often a mail drop.
Watch: Follow the Hull, Not the House

The Boat Is the Record, Not the Doorstep
Every technique that works on a house fails on a liveaboard, and for one reason: the person owns a vessel where you expected them to own an address.
Ordinary address work leans on a small number of records that all describe a piece of land. A deed names an owner. A county assessor’s roll ties that parcel to somebody who pays tax on it. A lease produces a tenancy. Utilities get switched on in a name. Voter files, licenses and credit headers all quietly copy an address out of one of those sources, which is why a routine search on a person who rents a flat resolves in minutes and feels almost effortless.
Someone living aboard breaks every link in that chain at once. There is no parcel because a boat is not real property. There is no assessor’s record for the same reason. Shore power and water are usually metered to the marina rather than to the berth-holder, so no utility account exists in the individual’s name. The slip is rented under a contract with a private business that has no filing obligation and no public index. And the postal address printed on their driving license may belong to a mail service two states away that they have never once physically visited.
What replaces all of that is the vessel. A boat is a titled, numbered, insurable, mortgageable asset that moves under its own power across state and national lines, and precisely because it moves, governments went to considerable trouble to make it identifiable. Production boats carry a hull identification number applied at manufacture. A documented vessel carries an official number too, and the regulations are exacting about it: preceded by the abbreviation for “number”, in block-type Arabic numerals at least three inches high, on a clearly visible interior structural part of the hull, permanently affixed so that removal or alteration would be obvious. The vessel’s name and hailing port are marked on the outside of the hull for the same reason. Ownership changes are recorded. Mortgages are filed and indexed. The whole apparatus exists so a stranger can identify a hull from a distance and then look it up — and that apparatus is the single best locate asset available on this topic.
So the order of work inverts. Instead of asking where this person lives and then confirming the address, you ask what this person floats on, and let the vessel’s paperwork surrender the addresses. The rest of this page is that trail: the federal register first, the state registers second, and then the harder, more interesting question of how to read the address you get out of either one. A useful companion at the other end of the same problem is our guide to what actually makes a person hard to find, because life aboard sits near the top of that list without the person having done anything evasive at all.
One honest caveat before the method. Not every boat is in a register. Small unpowered craft, dinghies, kayaks and in many states hand-propelled vessels of any size fall outside registration entirely, and a person living on a converted barge or a houseboat that never moves may sit in a genuinely strange category depending on the state. The techniques below cover the boats people actually live on. They will not manufacture a record where none was ever created.
What the Public Coast Guard Search Actually Returns
Almost everything written about this online is written by companies selling a filing service. Here is what the search itself does, measured rather than described.
Larger vessels are documented federally rather than registered by a state. Documentation is administered by the National Vessel Documentation Center, and the public window onto it is the Coast Guard’s Port State Information Exchange vessel search, hosted on the Coast Guard Maritime Information Exchange. It is free, it needs no account, and it is genuinely useful — provided you know in advance what it will and will not hand back.
You can search it by vessel name, hull identification number, official number, flag, vessel type, build year or gross tonnage. There is no field for an owner’s name. Run a search and the results table gives you eight columns: vessel name, service status, the official number, call sign, hull identification number, service category, flag and build year. No owner. No address. No hailing port. The words simply do not appear on the page. That is worth stating plainly because a whole tier of commercial sites ranks for this query by implying an owner lookup exists behind a fee, and the free search they are steering you away from is not withholding a name — it never had one to show.
Used for what it is, that search still earns its place early in the work. It confirms the vessel exists and is real rather than a name somebody remembered wrong. It tells you whether the documentation is current or lapsed, which is a live signal about the owner’s circumstances. It converts a boat name into an official number and a hull identification number, and those are the keys that unlock everything downstream. And where a family gives you three plausible spellings of a boat name, it settles which one is the actual vessel.
Ownership comes from an abstract, and anyone may order one
The name sits one document further in. Under 46 CFR 67.301, “any person may request the National Vessel Documentation Center to issue a General Index or Abstract of Title” for a vessel, on form CG-1332. There is no standing requirement, no membership, no showing of interest. A companion section does the same for a Certificate of Ownership on form CG-1330. This is the most under-used fact on the entire topic: the ownership record of a documented vessel is open to the public by regulation, and the commercial sites that rank for it charge a large multiple of the regulated fee without mentioning that it is regulated.
The fee schedule in the same part of the regulations sets an Abstract of Title at $25 and a Certified Copy of a Certificate of Documentation at $4. A Certificate of Ownership costs $125. Commercial filing services ranking for this exact query quote three times that for the identical document, which is a fair measure of how much of this subject is written to sell something.
What comes back is a chain, not a snapshot. An abstract shows the managing owner, the ownership history, recorded bills of sale, preferred ship mortgages, notices of claim of lien and their satisfactions. Each recorded instrument carries the names and addresses of the parties to it, which means a vessel that changed hands or was mortgaged three years ago is carrying three-year-old contact detail for your subject inside a document you can lawfully obtain. Lienholders matter too. A bank or a marine lender with a live mortgage has a servicing relationship with your subject and a strong commercial interest in knowing where the collateral is berthed.
The address on file has to be a residence
Here is where documentation quietly beats state registration. 46 CFR 67.113 requires every documented vessel to designate a managing owner, and specifies what address that person must give. For an individual it is not “an address” and not “a mailing address” — the regulation says it must be any residence of the managing owner. Where a vessel has several owners, the designated managing owner must be one of them and must have a United States address unless no owner does. That wording is doing real work for a searcher: the federal record is asking for somewhere the person lives, not somewhere their post arrives.
And it is meant to stay current. 46 CFR 67.321 obliges the managing owner to report a change of address to the documentation center within thirty days of it happening, a duty repeated inside 67.113 itself. People do not always comply, and non-compliance is itself informative — but a documented vessel whose certificate was renewed recently is carrying an address its owner affirmatively stood behind, which is a better provenance than most of what a commercial database will sell you.
State Registration Is Fifty Different Filing Cabinets
Most recreational boats never go near the federal register. They sit with a state agency, and which agency it is changes what you can lawfully get.
The first thing to settle is which system holds your vessel, because it cannot be both. Florida’s titling statute makes the fork explicit: an application for a vessel certificate of title must contain, among other things, a statement that the vessel is not a documented vessel. State titling and federal documentation are alternatives, so a single question — is this hull documented? — tells you which register to work and saves you from searching the wrong one twice.
Assume state registration by default. Federal documentation is generally reserved for larger vessels and is optional for many that qualify, so the ordinary thirty-five-foot sailboat somebody lives aboard year-round is far more likely to hold a state registration number than an official number. That number is painted on the bow in a format the state prescribes, which makes it readable from a dock without anyone having to be approached.
The agency changes, and so do the rules
Two real examples show the spread. In Florida, the Department of Highway Safety and Motor Vehicles is designated by Chapter 328 of the Florida Statutes as responsible for registering and titling vessels — the same department that runs driving licenses and car tags. In Texas, boat title, registration and tax sit with Texas Parks and Wildlife, a conservation agency with no motor-vehicle function whatsoever. Elsewhere the job lands with a department of natural resources, a game and fish commission, a secretary of state or a revenue department. There is no national vessel registration database to search and no single form of words that describes all fifty systems.
That structural difference has a direct legal consequence. The federal Driver’s Privacy Protection Act restricts the release of personal information from motor vehicle records, and personal information there expressly includes a name and an address. But the statute’s own definitions, at 18 U.S.C. 2725, define a motor vehicle record as one pertaining to an operator’s permit, a motor vehicle title, a motor vehicle registration or an identification card issued by a department of motor vehicles. A vessel record held by a wildlife agency is not that. Whether the federal restriction reaches a given state’s boat file therefore depends on which agency holds it and how that state treats vessel data — and where the Act does not reach, state public-records law and state-specific privacy statutes decide the question instead. This is exactly the kind of point that gets flattened into “boat records are private” by pages that have not read the definition.
What a state title application collects
Florida’s application, again as a worked example, is unusually explicit about addresses and rewards close reading. It goes to the county tax collector, not to a central state counter, which means the transactional record has a county-level home. It must contain the applicant’s name, the street address of the applicant’s principal residence, and, if different, the applicant’s mailing address. It must give the hull identification number, the vessel number, the Coast Guard official number if one exists, and a physical description of the hull down to material, propulsion and length. It must disclose every security interest known to the applicant with the name and mailing address of each secured party. And where the application accompanies a transfer, it must name the transferor with their street address and mailing address as well.
Read that list as a searcher rather than as a boat owner. A single state title application, correctly completed, distinguishes a residence from a mail drop as a matter of form design, names a lender, names the person who sold the boat, and pins the vessel to a county. Other states collect less and some collect more, but the shape is common enough that it is worth knowing what you are asking for before you ask. What no state does is publish it for browsing — access runs through a records request or a permissible-use channel, and getting that part right is not optional.
Three Addresses That Are Not the Same Address
The most common failure on this topic is not failing to find an address. It is finding one and misreading what it is.
By the time the record work is done you will typically hold two or three addresses for the same person, and they will disagree. They are not in conflict; they are answers to three different questions, and a database that flattens them into one field is where confident mistakes come from.
The hailing port is not a residence
Every documented vessel must display a hailing port on its hull. 46 CFR 67.119 requires the owner to designate one on application, requires it to be a place in the United States listed in a federal geographic names publication, requires it to name the state, and gives the documentation center the final word in a dispute. Notice everything the regulation does not require. It does not require the owner to live there. It does not require the boat to be kept there, or ever to have been there. Sentiment, a home town, a former berth, a yacht club, a brokerage’s convention — all produce hailing ports that are real places and useless as addresses. Treat a hailing port as a lead worth ten minutes and never as a location.
The address of record is the strongest thing you will hold
The managing owner’s address in a federal documentation file has a specific regulatory character: for an individual it must be a residence, and it carries a thirty-day duty to update. A state title record often has a comparable field, and where the form separates principal residence from mailing address, that separation is a gift. This is the address to build on. It is not proof of anything on its own — forms get filled in carelessly, boats get bought through entities, and people move without telling anybody — but among the addresses in play it has the best provenance and the clearest legal expectation of currency.
The mailing address is very often nobody’s home
Now the part unique to this population. People who live aboard have a genuine mail problem, and the ways they solve it all degrade an address as evidence. Some use the marina office, which produces a real street address that is an operating business rather than a dwelling. Some rent a box from a commercial mail receiving agency and quote it in a street-address format with a unit number, which looks convincingly residential and is not. Some use a mail-forwarding service marketed specifically at cruisers, whose address may sit in a state chosen deliberately for tax or licensing reasons and which the subject may never have set foot in. Some use a parent, an adult child or a sibling, which is the version most likely to be mistaken for a residence because a person really does live there — the wrong person.
None of that is evasion. It is what you do when your postbox floats. But it means a database hit showing your subject at a plausible suburban address may be recording nothing more than where their electricity bill gets posted, and the same address may return three or four unrelated names for exactly that reason. Our guide to working out who sits behind a mailbox covers the specific tells that separate a private mailbox from a dwelling, and that check belongs in this workflow rather than after it.
The practical rule is to grade rather than choose. An address that appears in a documentation file as a managing owner’s residence, is repeated on a recent recorded instrument, and matches a county property record for a relative, is a strong candidate for where post is received and a weak candidate for where the person sleeps. Meanwhile the berth — the marina and slip — may never appear in any record you can obtain, and is where they actually live. Holding both ideas at once is the whole skill here. Our note on how an address gets verified rather than assumed sets out the corroboration standard we apply before anything reaches a client.
Five Records, and What Each One Is Good For
They answer different questions. Ordering the wrong one first is the most common way to spend money and learn nothing.
| Record | What it gives you | What it will not do |
|---|---|---|
| Public federal vessel search | Confirms the hull exists; returns official number, hull identification number, service status, flag and build year, free and instantly | Names nobody. There is no owner column and no owner search field |
| Abstract of Title (CG-1332) | Managing owner, ownership chain, recorded bills of sale, mortgages and liens, with party addressesBest value | Covers documented vessels only, and reflects filings rather than where the boat is today |
| State registration or title file | Where most recreational boats actually sit; often separates principal residence from mailing address, and names lienholders | Fifty different agencies and access rules; no national index; released through a records or permissible-use channel, not a browse |
| Marina slip agreement | The only record that ties a person to the berth they physically occupy | A private contract with a private business. Not public, not indexed, and not obtainable by asking nicely under a false name |
| Commercial database header | Fast, broad, useful for building a starting hypothesis and a relative network | Flattens residence, mail drop and forwarding service into one undifferentiated address field |
| The point of the table | The free search tells you the boat is real. The abstract or the state file tells you who owns it and where the paperwork says they live. Only the berth tells you where they sleep, and that record is the one nobody can lawfully hand you on request. | |
Sequence matters more here than on most topics. Confirm the hull for nothing, establish whether it is documented or state-registered, then spend money once on whichever ownership record actually applies. Working that order is ordinary public-records research and skip tracing rather than anything exotic, and the discipline it takes is mostly the discipline not to buy the wrong document first.
The Slip Agreement Is a Contract, Not a Directory
The marina holds the one fact you most want. It is also the point at which most people on this topic do something they should not.
A berth is rented under a slip agreement between a boat owner and a private marina. It is a commercial contract, generally covering a term, a rate, an insurance requirement, sometimes a specific permission to live aboard, and it will carry the owner’s contact details and very often an emergency contact. Nothing about it is filed anywhere. There is no public index of slip holders, no register of who is moored where, and no obligation on any marina to answer a question about a customer.
Marinas also know this and are cautious for their own reasons. Their customers include people who chose the water partly for privacy, their staff are aware that boats get repossessed and marriages end, and many operators have a settled policy of confirming nothing about anyone. Others will engage readily with a court order, a lawful process request or a documented lien. The variation is enormous and none of it is predictable from outside.
Where the marina does appear in a public record
Being unindexed is not the same as being invisible. Where a berth is regulated rather than purely commercial — a municipal mooring field, a harbor district, a publicly run marina — a permit with a name on it may exist and may be reachable through that authority’s public-records process. The same is true when a vessel has drawn official attention: a citation, an impoundment, a derelict-vessel proceeding or a removal all require somebody to be named and served, which puts an owner into a file. Whether any of that is public where your boat sits is a question for the specific authority, and we check rather than assume. It is the reason a serious search does not stop at the state registration file.
What must not happen
Nobody at this firm telephones a marina pretending to be somebody they are not. Not a slip holder, not the owner’s relative, not a broker, not a surveyor, not a delivery driver with a parcel for the boat. Pretexting is the defining technique of the disreputable end of this trade and it is the fastest way to turn a legitimate research question into a legal problem for the person who asked. If you have read that trick somewhere and were about to try it, this is the paragraph asking you not to.
The lawful routes are unglamorous and they work. Where litigation is on foot, a subpoena directed at the marina is the correct instrument and is available to a party. Where a judgment exists, post-judgment discovery reaches records a marina holds. Where the question is service of process, the marina is not obliged to help but a court can be asked about a manner of service that fits the situation. Service rules for a person whose home floats are genuinely state-specific and worth taking advice on rather than improvising; our page on locating a person so papers can be served covers the locate half of that problem.
When the Vessel Never Sits in a Marina
A meaningful share of liveaboards do not rent a slip at all, and the whole marina-shaped approach quietly stops applying.
Slips are scarce, expensive and in many regions closed to liveaboard use entirely, so people improvise. Anchoring out means the vessel sits on its own ground tackle in open water with no berth, no shore power, no marina customer record and no address of any kind — the boat is reached by dinghy from a public landing, and the only fixed point in the person’s life may be where that dinghy is tied up. A mooring ball in a managed field is a middle case: the field is usually run by a municipality, a harbor authority or a club, and there is often a permit with a name on it. Some people alternate seasonally between a winter slip and a summer anchorage, so a record that was accurate in February describes nothing in July.
Then there are the categories that look like boats and behave like housing. A houseboat or float home that has not moved in a decade may be treated locally as a dwelling, may appear on a personal property tax roll, and may have a mailing address a postal carrier genuinely serves. A boat in dry storage or mid-refit sits at a yard for months under a work order that names its owner. Each produces a different record set, and guessing which one you are in wastes the most time.
Vessels also move, which is the fact that defeats naive searching. A cruising liveaboard may be in three states across a season and out of the country for part of the year. A hurricane season sends whole fleets several hundred miles. Documentation and registration records are addresses of the owner, not positions of the boat, and nothing in either file tells you where the hull is floating this morning. This is precisely why the ownership record is the target rather than the vessel’s location: an owner has a legal duty to keep an address current and no duty at all to report where they are anchored.
It is also why we do not sell vessel tracking as a locate product. Building a service around watching where a named private person’s boat goes is surveillance rather than records research, whatever the data source, and it is not what this page is teaching.
Where a Liveaboard Trace Goes Wrong
Six failures we see repeatedly, five of them committed with complete confidence.
Reading the hailing port as a home
It is a designation on a form, constrained by a geographic names list and nothing else. Owners pick home towns, old berths and places that simply sound right. Confirm it independently or drop it.
Paying for an owner lookup that does not exist
The free federal search returns no owner because it holds none to return. The document that does carry the name is an Abstract of Title, and the regulations set its fee well below what third-party sites quote.
Searching the wrong register entirely
Documentation and state titling are alternatives, not layers. Establish which one applies before spending anything, or you will search a federal file for a boat that was never in it.
Trusting a database address at face value
Mail services, marina offices and relatives’ homes all present as ordinary street addresses. An address that returns several unrelated names is a mail drop until something proves otherwise.
Telephoning the marina with a story
The single worst move available. It is pretexting, it burns the only cooperative source in the picture, and it converts a lawful records question into an unlawful one in about forty seconds.
Assuming the boat stayed put
Registration is an owner record, not a position report. A vessel confirmed in one state in spring is regularly several hundred miles away by autumn, and neither file has any duty to say so.
How We Work a Vessel-Led Trace
Four stages, in this order, because each one determines what the next is worth doing.
Purpose first, then facts
We establish your lawful purpose before we open a file, not after you have paid. Then we take the name, any spelling of the boat name, the region, and anything you already believe about the berth. Guesses are welcome as long as they arrive labeled as guesses.
Fix the hull, fix the register
Confirm the vessel through the free federal search where it may be documented, resolve a name into an official number and a hull identification number, and settle whether the ownership record lives with the Coast Guard or with a state agency. This costs nothing and directs everything after it.
Pull the ownership record that applies
An Abstract of Title for a documented vessel, or the state title and registration file through the proper access channel. We read the whole chain, not the top line: prior owners, lienholders and recorded instruments all carry dated addresses for the parties named in them.
Grade every address before it reaches you
Each address gets classified as a probable residence, a probable mail channel or a relative’s home, and corroborated against independent sources. You receive the classification and the source behind it, so you can weigh a weak address instead of acting on it as though it were strong.
What We Will Not Do to Find a Boat
Set out in full, because a page that has just explained how to trace someone through a public register owes the reader the limits in the same breath.
We are a public-records and skip-tracing research firm. We are not licensed private investigators and we make no such claim: we run no surveillance, we do not walk docks photographing hulls, we do not follow vessels, and we do not knock on a boat for you. What we do is identify, obtain and read records that a lawful requester is entitled to obtain, and then tell you honestly how much weight each one carries.
Every file opens on a stated permissible purpose. We ask what yours is at the start, we record it, and where a source is regulated we use it strictly inside the permitted use that applies — driver and vehicle data under the Driver’s Privacy Protection Act, financial identifiers under the Gramm-Leach-Bliley Act, and the varying state rules that govern vessel files held by motor-vehicle and wildlife agencies alike. Where a state treats its boat register as restricted, that is the end of the matter and we will tell you so rather than find a way round it.
We do not use pretext. Nobody here calls a marina, a harbourmaster, a boatyard, a lender, an insurer or a relative pretending to be someone else, and we will not coach you through doing it either. Nor do we reach into private financial accounts. No balances, no statements, no transaction histories, no account access — and no live location of a private individual’s vessel or handset, which is not something any firm can lawfully obtain however it is advertised. A recorded mortgage on a documented vessel is a public filing and we will read it. What sits inside the borrower’s account with that lender is not, and never becomes so because the collateral floats.
We are not a consumer reporting agency, and nothing we produce is a consumer report under the Fair Credit Reporting Act. Our work may not be used to decide any question that statute governs: employment, promotion or retention, credit, insurance underwriting, housing or a tenancy, tenant screening of any kind, a professional or government license, a government benefit, or any similar judgment about a person’s eligibility. Those decisions require a consumer reporting agency together with the disclosure, written authorization and adverse-action machinery the Act builds around them. Landlords, marinas evaluating a prospective liveaboard tenant, and employers checking a candidate all fall on the wrong side of that line for us. Where that is genuinely what you need, we will say so and decline the work rather than sell you something that cannot lawfully do the job.
Then the decline that matters most on this particular topic. Living aboard is a recognized way of becoming difficult to find, and a proportion of the people who do it chose it for exactly that reason — after an abusive relationship, a protective order, a stalking case, or a departure nobody was told about. A boat has no fixed address, no neighbors who knew you before, and it can leave a county overnight, and those are features rather than accidents for somebody rebuilding a life out of reach of one specific person. We will not take a case where the reason the subject is unreachable is that they are hiding from the person asking, whoever is asking and however the request is framed. We ask, we ask again, and where we cannot tell a worried family from a determined ex-partner we stop. If you are the person aboard and you believe you are being traced, speak to a victim-services advocate or to the court that issued your order about your state’s address confidentiality program, and take it as settled that no legitimate research firm should be helping anybody work around it.
Everything on this page is general information and not legal advice. Vessel registration, records access, service of process, liveaboard occupancy rules and mooring regulation are set by state and local law and differ sharply between jurisdictions, and the two states used above as examples are illustrations of that variation rather than a description of yours. Where you need an order rather than a record — a subpoena to a marina, permission for an alternative manner of service, a maritime lien or an arrest of a vessel — that is a lawyer’s work in the relevant jurisdiction, and on the water it is frequently a specialist one.
Who Brings Us a Liveaboard
Different reasons, one shared obstacle: the ordinary address search came back empty and nobody could say why.
Probate and estate work
An heir who sold up and moved aboard, with the estate unable to close without them.
Civil litigation teams
A defendant whose last known address is a mail service in a state they have never lived in.
Relatives ashore
A relative who went cruising and stayed gone, and a family with a boat name and a rough coastline.
Lenders holding a hull
A financed vessel whose borrower stopped answering and whose berth has changed.
Underwriters and surveyors
A claim or a survey where the named insured cannot be reached at any address on file.
Friends left ashore
Somebody who bought a boat, left a job and a ZIP code, and has been unreachable ever since.
Notice what none of these are. We do not take tenant screening, employment vetting or any other consumer-decision use, and that boundary applies here exactly as it does anywhere else on this site.
What You Actually Get From Us
An address, labeled. Every result we hand back carries the record it came out of, the date that record was created, and our read on whether it describes a place your subject sleeps or a place their post lands — because on this topic those two answers look identical and behave nothing alike. Where the vessel is already identified and the ownership record is a straightforward pull, that classification is usually back with you within 24 hours. Where the registers hold a boat and no usable current address for its owner, we will tell you that in those words instead of dressing up a stale filing as a find. And where a free federal search settles your question in five minutes, we would rather point you at it than take the work.
Questions People Ask From the Dock
Can you look up a boat owner by hull identification number?
Not through the free public federal search. You can search that database by hull identification number, and it will confirm the vessel and return its official number, service status, flag and build year — but the results carry no owner name and no address, and there is no owner field to search on in the first place. For a documented vessel, ownership comes from an Abstract of Title ordered from the National Vessel Documentation Center. For a state-registered boat, it comes from that state’s registration or title file through whatever access channel the state allows.
Are boat registration records public?
Partly, and the split is consistent: vessel data is generally open while owner data is generally restricted. Federally, the regulations let any person order an Abstract of Title for a vessel, which does name the managing owner. At state level it depends on which agency holds the file. Where boat records sit inside a motor-vehicle department, the federal Driver’s Privacy Protection Act may restrict release of the name and address; where a wildlife or natural-resources agency holds them, that Act’s own definition of a motor vehicle record may not reach them and state law governs instead.
How do I find out who owns a documented vessel?
Order an Abstract of Title on form CG-1332, which the regulations make available to any person without any showing of interest. It gives you the managing owner, the ownership history, and recorded instruments including bills of sale, preferred ship mortgages and claims of lien. The regulated fee is $25. A Certificate of Ownership on form CG-1330 is a heavier document at $125, and a certified copy of a vessel’s Certificate of Documentation is $4.
Does a hailing port tell me where the owner lives?
No, and this is the single most common misreading on the topic. The regulation requires the owner to designate a hailing port that is a place in the United States listed in a federal geographic names publication and that names its state. It does not require the owner to live there, or the vessel ever to have been there. Home towns, former berths, yacht clubs and pure sentiment all end up painted on transoms. Treat it as a lead to check, never as a location.
Can a marina be somebody’s legal address?
A marina address can certainly be a valid mailing address, and many liveaboards use the office or a dock box for post. Whether it works as a residence for voting, taxes, licensing or service of process is a separate question answered by state law, and residence, domicile and mailing address are three different legal concepts that a database will happily collapse into one field. From a searcher’s side the practical point is simply this: a marina address on a record tells you where post is received, not that anybody sleeps there.
How do liveaboards get their mail, and why does it matter?
Usually through the marina office, a commercial mail receiving agency, a mail-forwarding service aimed at cruisers, or a relative’s home. It matters because all four produce something that looks like an ordinary street address on a database record. A private mailbox rendered with a unit number is indistinguishable from a flat at a glance, and a forwarding service may sit in a state chosen for tax reasons that the subject has never visited. An address returning several unrelated names is the clearest tell.
Can you serve legal papers on someone living aboard a boat?
People are served aboard vessels regularly, but how it is properly done is state law and the answer turns on facts a general page cannot supply — whether the boat is a dwelling in that state’s sense, whether the marina is private property, and what your court accepts as substituted or alternative service where personal service keeps failing. Locating the person is our part of it; the manner of service is a question for a lawyer or the court in the relevant jurisdiction, and worth asking before an attempt fails rather than after.
What if they anchor out and never use a marina at all?
Then there is no slip contract, no marina customer record and no address of any kind attached to where they sleep, and the ownership record becomes the whole search. That is not as bad as it sounds: the managing owner of a documented vessel must keep a residence address on file and report a change within thirty days, and state title files often separate principal residence from mailing address. Municipal mooring permits, harbor authority records and derelict or removal proceedings can also put a named owner into a public file where a vessel has drawn official attention.
Have a Boat Name and Nothing Else?
That is often enough to start, because the hull is the part of this that leaves records. Send us the name, any hull or registration number you have seen, and the stretch of coast you think they are on, or put the question to our team and we will tell you honestly whether the registers are likely to hold anything worth buying.
