What's the estimated cost to get a COI on a 56 or 65 foot sailboat?

Sorry Capt Jack, but I'm a little slow when it comes to acronyms - especially when there is no connecting information as to what in the world you are talking about. I mean which boating COI are you referring to?

Certificate of Inspection?

Certificate of Integrity?

Cost of Insurance?

Cause of Insanity?

So... Just which "COI" are you referring to? I don't think you are talking about insurance, because you would know what that cost is.

Ok... "Certificate of Inspection" it is...

Now my anwwer is, no one can tell you what it cost. You won't know that until you identify the vessel and the purpose of the COI to the USCG. On the application it will ask you (among other things) Where the vessel is, and whether or not it is in the water... I don't think they charge US vessels in US waters a fee, but I do know there is a hefty (approx $2800) per diem for US flagged vessels outside US waters. So they may have a per diem charge within the US, if your vessel is more then a day away from an inspector.

the answer is to check with the local Coast Guard office that issues the COI; I've been out of that business a while but it used to be the actual inspection process, including the righting moment test was a nominal fee.....getting the boat up to CFR 33 & 41 ( 47? ) standards however isn't cheap....lifejackets, fire suppression systems, EPIRBs, life saving appliances if needed depending on route, yada yada yada was several to tens of thousand for a 15 to 47 passenger boat...

I pay 15.75$ per 1000$ for my boat with Cooperators. Boat is worth 175,000, insurance is 2750 per year. I do not know if they take age, or length into consideration. I think they are more concerned with the value of what they are insuring as opposed to the size.
