Life is short. You're not going to lie on your death bed
thinking "Boy, I really should have gotten an extra $900 discount on that Pearson
because of that wet core". The boat's lasted 30 years - probably much of it with damp core
. It's very likely to be about the same during the 3-5 years you might own her.
Second, don't focus on purchase price
. Boats are expensive to own - even if you do a lot of work yourself, other stuff - insurance
, dockage, broken stuff, engine
work - adds up. Let's say $10,000 over three years for this boat - if you are honest (note: honesty is generally discouraged when discussing boat costs with your significant other).
Now, the test. What was your reaction to the $10,000 number? Did you think "Gee, that's a lot of money
but I really want to buy this boat because it would be great to go sailing and I could fix it up and ......." - then welcome to the club
If you thought "Why the hell would I spend $10,000 on a $11,000 boat?" then you are too sane to buy this boat (or probably any other). Look into chartering.
