This is really a tricky question to answer. It is MUCH easier to take the top off and do the repair from the top down. Since otherwise the replacement core
and she'll keep falling off. On the other hand it also leaves a big scar in the deck that needs either new gel coat or paint
. And usually on a boat this old you really want to repaint the entire boat since color matching is incredibly difficult.
On the other hand taking off the bottom is easy from a cosmetic standpoint, but it is a real pain to effectuate the repair correctly. It also requires working over your head
with materials falling on you, likely in a cramped space, no way to brace the stuff well...
Frankly this is a crappy job no matter which way you go. But my recommendation would be to come at it from the top. Cut off the deck with an angle grinder and preserve the fiberglass
shell as a plug
. It is a less technical job, and doesn't require much in the way of specialty tools, just a good bit of fiddly work and grinding to do well. Coming from the bottom really requires vaccume bagging in my opinion, and that is a whole seperate skill set.
There are a lot of threads on core
repair here and on other forums
. I would suggest you spend some time reading them in detail and then coming back to ask specific questions.
