The problem is the boat market is in the toilet, similar to the housing market. Banks don't want to lend money on a 100k boat today that might be worth 60k in year or two. Even with 20% down ,the buyer would still be upside down.
I don't disagree with you on anything you posted. I'm just glad I purchased and financed before the chit storm. It would be nice to know I could move up easily if I wanted to, but I doubt it could happen for while.
