Do not launch your boat for a sea trial until three things are in place: an agreed price, a signed purchase agreement, and a refundable deposit of around ten percent. If the buyer runs the boat and disapproves it, the deposit comes back in full and both sides walk away clean.
Sellers ask whether that requirement costs them buyers. Every serious buyer I have worked with has signed and funded without argument. The ones who push back on it have never gone on to close. That makes a buyer's reaction to the deposit request the most useful qualification signal in the entire process, and it arrives before anyone has spent a dollar or an afternoon.
Should you let someone sea trial your boat before an offer?
No. A sea trial is the last step before closing, not part of shopping.
Running the boat is what a buyer does to confirm a deal they have already agreed to, and it is the most expensive thing you will do for anyone during the sale. Fuel on a diesel cruiser is not trivial. If the boat is stored ashore, someone pays to de-winterize, launch, and haul it back. You give up an afternoon. A single unqualified sea trial can cost a seller well into four figures before anyone has made an offer.
Showings are free. Sea trials are not. That line is the whole policy.
What has to happen before a sea trial
The sequence I run on every boat:
- An agreed price between buyer and seller.
- A signed purchase agreement.
- A refundable deposit, typically ten percent of the purchase price.
- The sea trial, with maintenance and repair records pulled and available.
- The buyer approves or disapproves, in writing, within a set window.
- The deal closes, or the deposit is refunded in full.
Steps one through three happen on paper and by transfer. Nothing about the boat moves until they are done. If you are handling the sale yourself, borrow the sequence as written — our full-service brokerage runs the same six steps on every listing.
How much deposit should you ask for before a sea trial?
Ten percent of the agreed purchase price is the figure I use, and it holds up across price ranges. On a $30,000 boat that is $3,000. On a $130,000 boat it is $13,000.
The deposit is the buyer's money the entire time it sits in escrow. Disapprove the boat after running it and it comes back in full, on a defined timeline, in writing.
That refundability is what makes the request reasonable, and it is the part that gets skipped over when someone objects. Nobody is being asked to risk anything. They are being asked to demonstrate they are past the browsing stage before your boat gets commissioned, fueled, and taken out on the lake.
How to tell if a boat buyer is serious
This applies whether you list with a broker or sell the boat yourself.
When you explain the deposit requirement, watch what happens next. A buyer who intends to own the boat treats it as a normal step. They ask what the deposit is, where it is held, and what triggers a refund. Those are the questions of someone thinking about a transaction.
A buyer who takes offense at the requirement is telling you something about how the rest of the deal would have gone. In my experience it has been a reliable indicator, and it costs nothing to collect. You learn it in one exchange, before the boat is commissioned and before you rearrange a weekend.
I would rather have someone walk at that moment than three weeks and two sea trials later.
Why a signed agreement outranks a verbal yes
I have had buyers stand on the dock with me, hear the process, agree to it out loud, confirm they understood, and then go three days without sending a signature or a deposit — while still expecting the sea trial to happen on schedule.
The lesson I took from it: the agreement to follow a process and the completion of that process are separate events, and only one of them counts. I now treat a verbal yes as the start of the conversation. The purchase agreement in hand and the deposit received are what put a date on the calendar.
Daily reminders do not change this. If the paperwork has not arrived, the trial has not been earned, and you should keep talking to other buyers.
Who should be allowed on your boat during a showing
Most yacht clubs and private marinas require children under a certain age to wear life jackets anywhere on the docks. That is a condition of your membership, not a suggestion. Walking a family down the finger piers without checking that rule puts your standing at the club at risk, on top of the obvious safety problem.
I have had a buyer arrive to view a boat with a spouse and three children under thirteen. Showing that boat responsibly meant addressing who came aboard before anyone stepped off the dock.
Children are not a problem. A boat that is not yours is a bad place to find out how curious a nine-year-old is. Upholstery, electronics, and canvas on a used boat are expensive and often irreplaceable on an older model. Part of representing a seller is deciding, in the moment and out loud, that some of the group stays on the dock.
Your insurance and your marina agreement do not stop applying because someone is there to look at the boat.
Selling the boat yourself
Everything above works the same for a private sale, and the screening matters more, because you absorb the cost of every wasted afternoon directly.
Two things get harder without a broker. You are negotiating with someone while also deciding whether to trust them, and those are difficult to do in the same conversation. And you handle the paperwork — the purchase agreement, the deposit escrow, and the title and registration transfer on the Ohio side. If there is a loan on the boat, the payoff has to clear before the title can move, which we cover in the lien payoff guide.

The short version for sellers
Require the paperwork and the refundable deposit before the boat leaves the dock. Say it early and say it plainly, so the buyers who were never going to close reveal themselves while it is still cheap. Decide who boards before anyone is standing on the swim platform.
All of it spends your fuel, your time, and your marina goodwill on the people who are actually going to buy the boat.
