I've owned 3 boats that I took on cruises from the U.S. to the Abacos. One was 1969 Westerly Centaur (26-feet) valued at about 10K. One was a 1981 Telstar 26 Trimaran
boat at around 16K and my most recent boat is a 1988 30-foot Hunter
valued at about 26K which I purchased about six months ago. I insured all these vessels for us coastal waters and Bahamas
including Turks and Caicos
. The Telstar took a bit of negotiating, but only because it was a 26-footer on a trailer with an outboard
. All other insured boats and quotes were very straight forward. To the best of my knowledge none of these policies limited the duration of my cruising time, but I did have a U.S. home port on the policy. I know all included summer sailing. I've had both liability only as well as more comprehensive policies.
The first boat required an insurance survey
. The second (Telstar) which had a liability only policy had no survey
and the last boat I had insured based on the purchase
survey. Prices ranged from about $350/year for the liability coverage on the Telstar (4-5 years ago), to $1,600 for the more recent and more comprehensive insurance
on my Hunter
. I have a second operator on this boat so have fairly comprehensive insurance including towing insurance. Prior to purchasing
my Hunter, I looked at and received valid insurance quotes on an early 80s Morgan
OI 30 and mid 80s Endeavour
32. All of the boats mentioned were at least 20 years old years old at the time they were insured or a quote was given.
I'm not in the insurance industry, so I can't speculate on your situation, but that's mine for what is is worth. I recommend you call a couple insurance carriers or agents and ask specifically about boats you are interested in.
All the best.
