Since the OP hasn't come back this may be moot but I'll throw it out there: I knew a couple that did a lease purchase
from a maritime academy. The academy apparently accepts boat donations to help fund the academy, refurbishes as needed and then lease/sells to raise money
. Terms are pretty stiff though. I believe it was something like a 1/3 down, payments for 2 or 4 years that amounted to another 1/3 and at that time the final 1/3 was due.
The maritime academy they found that did this was somewhere in Maine
The thought process was it got you into a boat while you were trying to sell something, i.e. another boat or a house or whatever.
