When Your Insurer Wants Hours With a Captain: What Actually Happens Next
The policy is bound, with a condition: hours with a captain before you run her alone. Here’s what that looks like, and how to make them count.
There is no course your underwriter wants you to pass. There are hours.
That distinction trips up a lot of owners the first time they move up. They assume the carrier wants a certificate, so they go take a classroom course, and then the broker calls back and says no, the policy still carries a captain’s warranty. What the carrier wants is time on this specific boat with a licensed captain aboard, and a letter at the end of it from that captain saying you’re fit to run her alone.
I’ve written before about the point where a length jump triggers this and why you should call your broker before the offer, not after. This is the article for what happens after the policy is written. The condition is in the binder. Now what?
What the condition actually says
Marine brokers call it a captain endorsement or a captain’s warranty. Sun Coast, a marine insurance agency, describes the common version as a supervised orientation: a licensed captain aboard for an agreed period, typically a range of days of active operation or a defined number of underway hours, after which the captain signs off and the endorsement drops. The same page notes the carrier will usually specify what the captain has to hold: a USCG Master’s license at the right tonnage and route, documented experience on similar boats, a clean record.
Two things to get in writing from your broker before you book anyone. First, the number. Some policies say twenty hours, some say forty, and owners on the trawler forums report being asked for a hundred. If your binder says “a period of supervised operation” without a number, ask for one. Second, whether the carrier needs to approve the captain in advance, or just needs their credentials on file. Some want a résumé and license copy before the first hour counts. Don’t find that out after hour twelve.
Ask your broker these four questions before booking a captain
How many underway hours does the endorsement require, and is that number in the binder?
Does the carrier need to approve the captain before hours start, or just receive credentials?
What exactly does the sign-off need to say, and who does it go to?
Does the endorsement drop mid-term once the letter is submitted, or at renewal?
How the captain gets onto your file
When an owner calls me about insurance hours, the first thing I send is not an invoice. It’s a one-page credential submission addressed to the underwriting department: my name, Offshore Captain Services LLC, my Mariner Reference Number, the Master 100 GRT and 50 GRT Near Coastal ratings, the towing endorsement, and a section describing the engagement as instructional coaching on the owner’s vessel. The owner fills in the vessel name and policy number, signs the affirmation, and sends it to their agent.
That form does two jobs. It puts a licensed, verifiable captain on the carrier’s file before we touch the boat, and it gives the owner something to forward instead of a phone description of “a guy from the yacht club.” I’ve laid out what your carrier needs to see for a delivery and the paperwork is the same idea. Underwriters like documents. Send them one.

What the hours look like
Here’s the part nobody explains, because most captains who do insurance sign-offs treat the hours as a ride-along. You drive. They sit. At the end they sign.
I run them as coaching, because you’re paying for the time either way and you should come out the other end able to run the boat, not just permitted to. The hours map onto the five Captain’s Coaching modules, and on a forty-hour requirement they land roughly like this.
The first block is the dock. Engine room checks before a line comes off, then exiting and entering your own slip, in whatever wind the day gives us. On a boat that just went from a single sterndrive to twin inboards, this is where the real learning curve is, and it’s where a carrier’s concern about you actually lives. Nobody loses a boat at cruising speed on Lake St. Clair. They lose the corner of a swim platform at the dock.
The second block is running the boat. Trim, throttle, the marina idle-out, channel markers, right of way in a crossing situation, radio. I want the owner comfortable enough that when a freighter comes around the bend on the Detroit River they’re already on the correct side and the correct channel.
The third block is anchoring and the fourth is trip planning, because the sign-off letter I write says you can operate the boat, not that you can get it out of a slip. If your first real trip is Port Huron to Harbor Beach, I’d rather the trip planning happened with me in the cockpit.
Somewhere in there we do the first fifty miles that every new-to-you boat needs regardless of what the insurer said.
The letter
At the end I write the sign-off. It’s not a form letter. It names the vessel, the dates, the hours logged, the conditions we ran in, and what you demonstrated: docking in a crosswind, anchoring, a man overboard drill, radio procedure, whatever the hours actually covered. It states plainly that in my judgment you’re competent to operate the vessel without a captain aboard. It’s on letterhead with my reference number, and it goes to you to submit to the carrier, with a copy to your agent if you want me to send it.
Sun Coast’s page describes the path off the endorsement as exactly that: complete the period, have the captain sign a satisfaction letter, submit it, and request the endorsement be lifted mid-term or at renewal. I’d add one thing. Keep a copy. The next time you move up, that letter is part of your experience file, and carriers read a prior sign-off as favorably as they read years of ownership.
What I’d tell you before you book anyone
Two things.
Pick the captain for how they teach, not just for the ticket. Any licensed Master can satisfy the underwriter. Not every one of them will leave you better at running your boat than they found you, and you’re spending forty hours with this person on a boat you just paid a lot of money for. Talk to them first. If it doesn’t feel like someone you’d want aboard anyway, keep looking.
And do the hours on your own water. A sign-off from a training captain in Florida on a school boat satisfies some carriers. It does not teach you how the current runs at the head of the Trenton Channel or what a south wind does to the mouth of the Clinton River. The insurer is asking you to prove you can handle this boat. The honest way to do that is on the water you’ll actually be on.
If your binder just came back with a captain’s warranty on it, a quick call sorts out the rest. Bring the binder. I’ll bring the form.
