Boat loans on classics????

[abjohn]

Let's say your looking at a classic boat, 30+ years of age. However this boat has had a grocery list of upgrades and new power. You're basically looking at a new boat but the bank still sees it as a 30 yr old boat. We're talking about something that may have cost upwards of $35,000 to be for sale today.
Anyone know of lenders that specialize in older boat loans. A group that understands a refurbed Potter has less depresiation than some Palm Beach that ain't worth shat the minute ya drive it off the lot. Maybe one that would take the time to review a thorough survey/estimate by a boat industry professional.
I suppose yall can see the discouragment I'm encountering with my dealings with banks and their loan SOPs lately
