Boat/Us does not require surveys on their policies. Unless you have a specialty boat or are trying to insure for a seemingly crazy amount most companies don't require one. I have insured dozens of different boats over the last 15+ years and have NEVER been asked for one. Yep, dozens. Many people have their addictions be it drugs, alcohol, gambling, women, etc. Mine is boats
Try
www.quotemyboat.com, Global Marine Insurance, usually underwritten by Markell. I find them to be good on larger boards but not as good as Boat/US on smaller boats.
If you end up needing a survey I can point you in the right direction of who to call.
