Four years ago I had an insurance survey done on my 1980 boat. This resulted in my obtaining a competitive insurance quote for an agreed upon value offer that I happily accepted. However, over the next four years the renewal price for that same policy increased 32%. I tried shopping around, including BoatUS, and every insurance company stated that they needed a survey that was no older than two years. I paid $400 for the survey four years ago. My questions to the forum are as follows: Do you have to obtain a survey every two years for your agreed value policy? How much does it cost you for the survey?
