This isnt unusual. Especially for banks that dont do many boat loans. What they are probably needing is a USED BOAT BOOK OUT SHEET. You can do this yourself by going to NADA.com. Find your boat add everything to it , then it will give you a value. For a Bass Cat , you will have to value boat , trailer then engine seperate.Once you get these just print it out.This is what most banks will want. You might even get them to do it for you while your there with them.Good Luck
