- 46 CFR 67.167(b)(1) invalidates a Certificate of Documentation and its endorsements immediately on a change of vessel ownership in whole or in part, and an exchange must be applied for.
- The same list is triggered by a change in general partners, a change in a corporate owner's state of incorporation, a name change, a hailing port change, or command by a non-citizen.
- 46 CFR 67.301 lets any person request a General Index or Abstract of Title from the National Vessel Documentation Center, which is the buyer's diligence tool.
- 46 U.S.C. 31321(a) makes a filed instrument valid against any person from the time of filing, so a recorded mortgage binds a buyer whether or not they knew of it.
- 46 CFR 67.99(c) states that a Manufacturer's Certificate of Origin is not evidence of the facts of build, which is the document a seller is most likely to hand over.
- Endorsements are valid for one year, and a Certificate carrying both a recreational and a commercial endorsement is valid for one year only.
On the day you buy the boat, its federal documentation becomes invalid. Not expired. Invalid immediately, by operation of a regulation that names change of ownership as the trigger.
That is the shape of the whole diligence problem in this trade. Buying a guiding business is largely an exercise in establishing what does not transfer, because the things that do transfer are the easy part. The documentation has to be exchanged, the credential was never movable, any recorded instrument against the hull follows the hull, and the entity's history comes with the entity. Below, each of those is read from the regulation or the statute, along with the one diligence tool most buyers do not know exists. None of it is legal advice, and requirements do change: call the issuing office to confirm the exact rules that apply before money moves, and get the transaction itself reviewed. The running the business hub collects the adjacent pieces.
| Event | Authority |
|---|---|
| Ownership of the vessel changes in whole or in part | 46 CFR 67.167(b)(1) |
| General partners of a partnership change by addition, deletion or substitution | 46 CFR 67.167(b)(2) |
| The state of incorporation of a corporate owner changes | 46 CFR 67.167(b)(3) |
| The name of the vessel changes | 46 CFR 67.167(b)(4) |
| The hailing port changes | 46 CFR 67.167(b)(5) |
| The vessel is placed under the command of a non-citizen | 46 CFR 67.167(b)(6) |
What happens to the documentation at closing?
It becomes invalid the moment ownership changes.
Section 67.167(b) of Title 46 states that a Certificate of Documentation together with any endorsements on it becomes invalid immediately, subject to a stated exception, when any of six events occurs.
The first listed is that the ownership of the vessel changes in whole or in part, so a partial sale triggers it as surely as a complete one.
Subsection (a) then requires the owner to apply for an exchange of the Certificate where any of those events occurs, in accordance with the relevant subpart.
The practical consequence is that a buyer takes delivery of a documented vessel whose documentation has just stopped being valid, and the exchange application is not an administrative afterthought but a condition of operating.
Section 67.167 is carried on the eCFR.
Which vessels need documentation at all is covered in the second boat piece.
What else on that list matters?
Two events that catch people who were not buying a boat at all.
Paragraph (b)(2) invalidates the Certificate when the general partners of a partnership change by addition, deletion or substitution, which means a change in the ownership structure of the operation reaches the vessel paperwork even where the hull never moved.
Paragraph (b)(3) does the same where the state of incorporation of any corporate owner changes, so a reorganisation has the same effect.
Paragraph (b)(4) and (b)(5) cover renaming the vessel and changing its hailing port, both of which a new owner frequently wants to do and neither of which is free.
Paragraph (b)(6) invalidates it where the vessel is placed under the command of a person who is not a citizen of the United States.
Taken together, the list means that almost any change a buyer plans in the first season requires the exchange, so it is worth doing once and doing it properly.
What happens to the partnership itself is covered in the partnership piece.
Price the diligence, because it is cheap against the exposure. An abstract of title, a survey, and a few hours of professional review might total $1,500 to $3,000 on a $180,000 purchase, which is under 2 per cent. Against that, a single undischarged recorded instrument on the hull, or a documentation exchange discovered in week 1 of a booked season, costs more than the whole diligence budget and costs it at the worst possible moment. The asymmetry is not close, and yet the step most commonly skipped in a small guiding sale is the one that costs 1 per cent of the price.
Can a buyer check the title history?
Yes, and it is available to anyone.
Section 67.301 provides that any person may request the National Vessel Documentation Center to issue a General Index or Abstract of Title for a vessel.
That single sentence is the most useful thing on this page, because it means the recorded history of a documented hull is obtainable by a prospective buyer without the seller's cooperation.
What that record shows is the chain of recorded instruments, which is exactly where an outstanding mortgage or an unexpected prior interest would appear.
It is not a substitute for professional advice and it does not reach anything that was never recorded, but it turns a category of risk from invisible into checkable.
Requesting it before agreeing a price rather than after is the whole of the technique.
Section 67.301 is a single sentence, and it is on the eCFR.
What the seller should have assembled is covered in the valuation piece.
No transaction advice is given here. Whether a particular purchase is sound depends on the hull, the records, the state and the arrangement, and that belongs to a lawyer and an accountant looking at the actual documents. Documentation and recording rules change, so check the current requirements with the agency before you rely on any of this.
Why does recording matter to a buyer?
Because an unrecorded instrument is invalid against you, and a recorded one is not.
Section 31321(a)(1) of Title 46 provides that a bill of sale, conveyance, mortgage, assignment or related instrument covering any part of a documented vessel, or a vessel for which an application for documentation is filed, must be filed with the Secretary to be valid against any person, with three exceptions.
Those exceptions are the grantor, mortgagor or assignor; that person's heir or devisee; and a person having actual notice of the instrument.
Paragraph (a)(2) then provides that an instrument filed in substantial compliance is valid against any person from the time it is filed.
Read the two together and the position for a buyer is clear. A recorded mortgage is good against you whether or not you knew about it, and the way you find out is to look at the record.
Paragraph (a)(3) adds that the parties must use diligence to ensure the parts of an instrument for which they are responsible are in substantial compliance, which is a duty on both sides rather than on the filer alone.
Section 31321 sits in the codified compilation published by the Law Revision Counsel, with a parallel text in the Title 46 volume on govinfo.
An inherited entity brings an inherited classification, which is the structure comparison piece.
What does an instrument have to contain?
A date of execution and an acknowledgment, and the Coast Guard will not supply the second.
Section 67.207(a) requires every instrument presented for filing and recording to bear the date of its execution and to contain an acknowledgment.
Subsection (b) then states that no officer or employee of the Coast Guard is authorised to take such acknowledgments unless the instrument is executed on behalf of the federal government.
Which means the acknowledgment has to be arranged before the paperwork is submitted, and a bill of sale signed at a boat ramp without one is not in a state to be recorded.
That is a small point that delays closings, and it is entirely avoidable by reading the requirement in advance.
It is also a reminder that the recording step has its own formalities separate from whatever the sale agreement says.
Section 67.207 can be read at the eCFR.
What the surrounding agreements should cover is covered in the booking terms piece.
How long is an endorsement valid?
A year, for the endorsement a working boat carries.
Section 67.163(a) states that endorsements on Certificates of Documentation are valid for one year, except recreational endorsements which may be valid for one to five years.
It then adds the point that catches dual-use hulls: a Certificate carrying both a recreational and a commercial endorsement is valid for one year only.
Prior to expiry the owner must apply for renewal by executing the prescribed renewal application, certifying that the information on the Certificate and its endorsements remains accurate and that the Certificate has not been lost or mutilated.
For a buyer that means two dates to establish at diligence: when the current endorsement expires, and whether the certification on the last renewal was accurate given everything else you have found.
An inaccurate certification is a different problem from an expired one, and only the record will tell you which you are looking at.
Section 67.163 can be read at the eCFR.
What the annual inspection cycle adds is covered in the maintenance costs piece.
What about the build history?
There is a specific document, and the one people produce is not it.
Section 67.99(a) provides that evidence of the facts of build may be a copy of the completed builder's certification form, or another document containing the same information, executed by a person with personal knowledge of the facts of build.
It defines who qualifies: somebody who constructed the vessel, supervised the actual construction, or is an officer or employee of the building company who has examined the company's records concerning the facts of build.
Subsection (b) requires a separate certificate from each builder involved in the construction, which matters for a hull finished by somebody other than whoever moulded it.
Then subsection (c) states it plainly: a Manufacturer's Certificate of Origin is not evidence of the facts of build.
That is precisely the document a seller is most likely to hand you, so knowing it does not satisfy the requirement saves a round trip.
Why the paperwork trail matters as much as the hull is covered in the bookkeeping piece.
What does the buyer inherit on the employment side?
Whatever arrangements existed, and their record.
An operation with people guiding for it has a classification position, a set of pay arrangements and a recordkeeping history, and buying the business means forming a view on all three.
The question a buyer should ask is not whether the seller called them contractors, since that is not determinative, but what the arrangements actually looked like and what records exist to describe them.
Where the records are thin, the buyer is taking a position they cannot evaluate, and where the arrangement was informal the buyer inherits an informality that they will have to resolve.
That is a reason to structure the purchase as an acquisition of assets rather than of an entity where the employment history is opaque, and it is a question for a lawyer rather than a preference.
It is also a reason to ask for the hours records, which the wage regulations require an employer to keep and which therefore ought to exist.
How that classification question works is covered in the classification piece.
What should be asked about the bookings?
Not the total, but the composition.
A revenue figure tells you almost nothing about whether the business will still exist next season, because it does not distinguish a returning client from a first-time enquiry.
The figures worth asking for are the number of clients who booked in more than one of the last three seasons, the share of bookings that arrived through the website rather than through the seller personally, and the lead time between booking and trip.
Each of those speaks to whether demand attaches to the business or to the person, which is the only question that matters in the price.
A seller who cannot produce them is not necessarily hiding anything, since most guiding operations do not track them, but the buyer then has no evidence for the premium above the boats.
Which is a fair thing to say out loud during a negotiation, because it is true and it is checkable.
What those figures mean in practice is covered in the profitability timing piece.
Does the insurance history matter?
More than the current policy does.
A policy in force tells you what the seller bought. A loss history tells you what happened, and the second is the thing that follows the operation.
A pattern of small documented incidents handled properly reads very differently from a blank record followed by one claim, and it also reads differently to the insurer who will quote you.
So the request is for the loss runs rather than the certificate, and for whatever incident record the operation kept alongside them.
Where no incident record exists, that is itself information about how the operation was run, and it is worth weighing rather than ignoring.
The cover will need rewriting in the buyer's name in any event, since the named insured has to describe whoever actually owns the hull.
What the cover has to respond to is covered in the liability insurance piece.
What breaks in the first season after a purchase?
The handover, and it breaks quietly.
Clients who booked with a person and arrive to find somebody else are a churn risk that no purchase agreement addresses, and they leave without complaining.
Referral relationships behave the same way, since a shop or lodge sending work was sending it to somebody rather than to a business name.
The mitigation is a transition in which the seller is visibly involved for a season, which costs money and is worth paying for where the demand is personal.
What does not work is an announcement, because the thing being transferred is trust and it does not transfer by notification.
Which argues for negotiating the transition alongside the price rather than after it, and for writing down what the seller will actually do.
How those referral relationships are built is covered in the shop partnerships piece.
What is genuinely worth buying?
Demand, and very little else.
Tangible property can be bought anywhere and usually cheaper, so a purchase price above the value of the boats is being paid for something other than boats.
What justifies it is demand that will continue after the seller leaves: a booking record with repeat clients, a brand and web presence that generates enquiries, and referral relationships reduced to something more durable than a friendship.
What does not justify it is the seller's own reputation and the seller's own credential, because both walk out with them.
Which gives the buyer a straightforward test: ask what fraction of last season's bookings would have happened if a different competent person had answered the phone.
If the honest answer is small, you are buying a boat with a premium attached to it.
Why the credential cannot come with the business is covered in the entity piece.
What the demand side actually requires is covered in the marketing cost piece.
Is there a case for starting instead?
Frequently, and it deserves an honest comparison.
The premium in a purchase price above the tangible property is being paid to skip the years it takes to build demand, and that is a real thing to buy.
Against it, a purchase carries somebody else's arrangements, somebody else's records and somebody else's reputation, and the buyer inherits all three whether or not they were examined.
Starting carries none of that and takes longer, which is a straightforward trade rather than a close call once the premium is quantified.
The test is whether the demand being bought is genuinely transferable, because a premium paid for demand that leaves with the seller purchased nothing at all.
Which is the same question as before, asked from the other side, and it is the only one that changes the answer.
What building it from nothing involves is covered in the marketing cost piece.
What should a buyer do, in order?
Pull the record, establish what transfers, then talk about price.
Request the abstract of title before agreeing anything, since it is available to any person and it tells you what is recorded against the hull.
Establish that the documentation exchange will be needed, budget the time for it, and do not plan a closing that assumes the existing certificate keeps working.
Ask for the builder's certification rather than the manufacturer's document, and for a separate one from each builder involved.
Confirm which authorisations transfer and which do not, with the issuing agency rather than with the seller, and treat the credential as non-transferable because it is.
Then test the demand, since that is the only part of the purchase price that is not available cheaper elsewhere, and take advice on the transaction before signing.
What the numbers to ask for look like is covered in the numbers piece.
How this was checked. The rule that a Certificate of Documentation together with any endorsements becomes invalid immediately, subject to a stated exception, upon a change in ownership of the vessel in whole or in part, a change in the general partners of a partnership by addition, deletion or substitution, a change in the state of incorporation of a corporate owner, a change in the vessel's name, a change in its hailing port, or the vessel being placed under the command of a person who is not a citizen of the United States, together with the requirement to apply for an exchange of the Certificate where such an event occurs, comes from 46 CFR 67.167(a) and (b). The provision that any person may request the National Vessel Documentation Center to issue a General Index or Abstract of Title for a vessel comes from 46 CFR 67.301. The requirement that every instrument presented for filing and recording bear the date of its execution and contain an acknowledgment, and the statement that no officer or employee of the Coast Guard is authorised to take such acknowledgments unless the instrument is executed on behalf of the federal government, come from 46 CFR 67.207. The one year validity of endorsements on Certificates of Documentation, the one to five year alternative for recreational endorsements, the one year limit where a Certificate carries both a recreational and a commercial endorsement, and the renewal application requirement including the certification that the information remains accurate and the Certificate has not been lost or mutilated, come from 46 CFR 67.163(a) and (b). The forms of acceptable evidence of the facts of build, the categories of person qualified to execute it, the requirement of a separate certificate from each builder involved in construction, and the statement that a Manufacturer's Certificate of Origin is not evidence of the facts of build, come from 46 CFR 67.99. All were read on the Electronic Code of Federal Regulations on 26 July 2026. The requirement that a bill of sale, conveyance, mortgage, assignment or related instrument covering any part of a documented vessel be filed with the Secretary to be valid against any person other than the grantor, mortgagor or assignor, their heir or devisee, and a person having actual notice, the validity of an instrument filed in substantial compliance against any person from the time of filing, and the duty on the parties to use diligence to ensure substantial compliance with the filing and documentation requirements, come from 46 U.S.C. 31321(a), read at the Office of the Law Revision Counsel and cross-checked against the copy of Title 46 published on govinfo. No view is offered on any particular transaction, and all arithmetic uses stated illustrative figures.

What happens to the vessel documentation when I buy?
46 CFR 67.167(b) provides that a Certificate of Documentation together with any endorsements on it becomes invalid immediately, subject to a stated exception, when any of six listed events occurs, and the first is a change in the ownership of the vessel in whole or in part. Subsection (a) requires the owner to apply for an exchange of the Certificate. So a buyer takes delivery of a vessel whose documentation has just stopped being valid.
What else invalidates it?
A change in the general partners of a partnership by addition, deletion or substitution; a change in the state of incorporation of a corporate owner; a change in the vessel's name; a change in its hailing port; and the vessel being placed under the command of a person who is not a citizen of the United States. Since a new owner frequently wants to rename the boat or change its hailing port, the exchange is worth doing once and doing properly.
Can I check what is recorded against the hull?
Yes. 46 CFR 67.301 provides that any person may request the National Vessel Documentation Center to issue a General Index or Abstract of Title for a vessel. That means the recorded history of a documented hull is obtainable without the seller's cooperation. It does not reach anything never recorded and is not a substitute for advice, but it turns a category of risk from invisible into checkable.
Does an unrecorded mortgage affect me?
46 U.S.C. 31321(a)(1) provides that a bill of sale, conveyance, mortgage, assignment or related instrument covering any part of a documented vessel must be filed with the Secretary to be valid against any person, other than the grantor or mortgagor, their heir or devisee, and a person having actual notice. Paragraph (a)(2) makes an instrument filed in substantial compliance valid against any person from the time of filing. So a recorded mortgage binds you whether or not you knew about it, and the way to find out is to look at the record.
What paperwork does a bill of sale need?
46 CFR 67.207(a) requires every instrument presented for filing and recording to bear the date of its execution and to contain an acknowledgment. Subsection (b) states that no officer or employee of the Coast Guard is authorised to take such acknowledgments unless the instrument is executed on behalf of the federal government, so the acknowledgment has to be arranged before submission.
Is a Manufacturer's Certificate of Origin enough for the build history?
No. 46 CFR 67.99(c) states directly that a Manufacturer's Certificate of Origin is not evidence of the facts of build. Subsection (a) accepts a copy of the completed builder's certification, or another document with the same information, executed by somebody who built or supervised construction or who is an officer or employee of the builder and has examined its records. Subsection (b) requires a separate certificate from each builder involved.
What is actually worth paying a premium for?
Demand that continues after the seller leaves. Tangible property can be bought anywhere and usually cheaper, so a price above the value of the boats is being paid for something else. What justifies it is a booking record with repeat clients, a brand and web presence that generates enquiries, and referral relationships that are more durable than a friendship. The seller's own reputation and credential do not transfer.
