I would have to second Palarran, post #8 - - common sense says if you give somebody money
in anticipation of buying
something and getting delivery
later (exactly what department stores in the USA do with holiday "law-aways") you do not own anything but a receipt for your "deposit."
The boat was and is still owned by the company up until you take possession of the clear Title/certificate of ownership
. So what are your saving? You don't own anything.
When you do take ownership
(possession of a clear title) then and only then you have "purchased" the boat. But now the boat is a "used boat" so the taxes
, whatever the local laws require, may be less than on a "new purchase
Looking at it another way, you seem to be suggesting that between the start of the "deal" and your taking ownership, you are "renting/leasing " the boat when you use it. And over the interim years your rent is being "applied" as credit to the "new boat cost" and at the end of the agreement you end up buying
a "used" boat.
This appears to be identical to the world's airline companies use of what is called "lease-back." The airline company buys a new airliner, sells it (or an older paid-off aircraft that they already own) to a aircraft leasing company, and then rents it back on lease
. The corporation's "lease payments" are deductible whereas outright purchases are treated less advantageously tax-wise.
