Owner Finance? - FP Eleuthera wanted

[Krakken]

I provide rent to own cars for clients in Australia! However buying the catamaran I want is proving to be a mission to say the least. I am stuck on purchasing a FP Eleuthera (60), they are few and far between. That's problem one.
Problem two: I can finance 50% of the boat here in Australia (not overseas) and pay cash for the other half - but there are none for sale here - problem two.
So I decided to start this thread to see if there is another option available to solve these two problems?
Maybe vendor finance secured by asset's I own, has anyone tried to achieve this?
