Just received my boat insurance renewal & I'm not sure that its worth the insured amount. Thats not their fault, its just that I havent adjusted the value over the years. 1994 4.5 mtr Quintrex bay hunter. 40 hp  merc. good cond  i dont want to be paying more than i need to. Is there a source of information on boat valuations as there is with red book etc for cars? Or can some of you make a guess at what it might be worth?
