I highly doubt for a itty bitty soft spot that my boat will just crash and sink my transom is solid it's a small soft spot.
I will bet you $100 cash that you find the foam wet, the stringers rotten, and the transom rotten
the reasons that we are concerned is that we see hundreds of new boats in the restoration forums every year that have one little soft spot. and every single one of them looks deeper to find a rotted structure. we also see pictures of boats that have sank because of a hull breach. I personally know two people that sank their boats because the hull breached from rotten structure and the foam was wet. one boat sunk in less than 45 seconds when the transom was ripped loose from the outboard
your boat was made in the early 80's. a hay-day for disposable income for the middle class...... so boats were churned out by the millions. boats designed to last only 15 years and be replaced. if well maintained, they lasted 30 years
your boat is now 37 years old.... if garage kept and washed after every use. age isnt an issue.
your boat was built in the 80's which was a time of lack-luster build quality because they were slapping them together as quick as they could
you have a soft spot in the floor. I bet you will find that simply pulling up the cover for the ski locker and sticking your head in there you find the stringers under there dark and rotten. do a simple drill test (just search the forums for drill test)
you may even find that you have a layer of wood screwed over the top of your fiberglass deck and then covered with the carpet. this is known as a deck-over
