I know what boat this is, nice score! Wish I saw it right away
Just dealt with this recently. If you tell one insurance company what you “paid” for it they will insure somewhat based on that value unless you get a survey. If you tell a second insurance company you paid more then you can get insured for a higher value. Not sure of the legality in doing this but it doesn’t make any sense to insure something for less than what it’s worth to replace.
I have no experience with insurance claims and total loss, would they ask for a purchase receipt? Considering the condition of that boat I’d consider getting a survey as I doubt there’s anything wrong with it
