Re: 1977 sea ray
Nice 'Ray.
It looks like it was well taken care of.
My '69 is still dry.
Go all the way forward. Where the eye bolts comes through, there is some exposed foam. If this is wet you're really in trouble.
The only holes int he floor should be from the seats where they are lagged in. The floor is very well sealed with glass.
If you must know, yes you will have to drill and take a sample.
The least intrusive place to this IMO is under one of the seats.
Check your forward bilge area for cracks where water might get through too...another potential candidate for a core sample although I personally would not drill through in this area unless I were prepared to reglass it.
You could also weight at a local truck scale, truck weigh station, gravel/sand supplier or dump, and go from there. You would of course have to know the weight of the boat, truck and trailer.
