Maybe the best news is that there are literally hundreds of examples of
half finished do-it-yourself boat restoration projects being sold for
pennies on the dollar by discouraged owners.

With luck, you'll find one of the 5-10% attempted by a boat owner who
didn't actually destroy the boat in the process and be that much closer
to completion.

As cheaply as you can buy a total mess, you might find that a boat that
was once a derelict but has been brought along by several tens of
thousands of dollars back toward respectability will resell, prior to
completion, for pretty close to the original total mess figure. Moral
of the story- pick up somebody else's labor for nothing and try to
avoid
selling your own for the same price. Make sure you have the time,
energy, money, and expertise to finish the job- or don't bother to
start.

There are some good reasons why top flight boatyards have long wait
lists, despite some very high pricing.
