The problem with some bankers is they don't understand value when it comes to dealing with yachts. A 1982 to a bank officer that knows nothing about a yacht will think any amount of equity is gone. I would suggest ask the loan's officer if he/she ever dealt with loans for yachts, if YES present your survey to him/her and talk as if you know it inside out, if the answer is NO, find someone that has.
It could be frustrating dealing with the ignorant.*
