My friends Islander is showing it's age now...
It's out of the water this year because of big time blistering...
I don't know if that happens in fresh water, but on a 30+ yr. old boat in saltwater, it's a big problem...
(the only "rot" you'll see on an Islander, that hull is solid as a rock!)...
They are repairing all the blisters and removing the all the old gelcoat & replacing! hull & deck... Big job! esp. the deckwork...
and he and his brothers are doing the work themselves...
The boatyard want's more to do the work than the boat is worth in today's market...
