"if I cant sell the boat for what it is worth, "
You might want to rethink that. Whatever you sell the boat for, IS what it is worth. If you make a good job of advertising or marketing
it, it will be gone in 90 days or less, and the money
you get WILL be roughly what it would cost to replace it a few months later. Beyond that...markets change over time. But of course, you won't be spending upkeep or storage money
over time if you sell the boat, too. Now, i freplacing it means wasting a big chunk of sales tax 'again', and more repairs
to upgrade things, that's something to consider too.
Some things are unique, or hard to replace or match. But unless there's something really special, getting what it is worth is simply a matter of figuring out how to advertise these days.
Good luck with the health issues.
