Soft spot

[Splitseas]

Hello everyone. I'm new on here and have been reading a lot of the info posted on repairs by others. I have a 1973 20' CC. There is 1 soft spot between the console and the port side. My question is, can this be repaired w/out cutting the floor? I was wondering if you could remove the deck above the gas tank and repair from underneath? Any suggestions are greatly appreciated. Thanks!!

Being a 73' I'm not sure whether your deck is plywood or balsa, I'm sure someone will pipe in that knows, I do know that it would be VERY hard to fix from underneath,if not impossiable, there will be a stringer between the tank and the spot, you need to determine if the deck is wet or if there is delamanation or a void between the fiberglass and the plywood or balsa, if it is dry I would drill some small holes and inject epoxy till they come out the other holes. If it is wet you could cut a square out, dig out the wet balsa and fill with coring and put the deck piece back in, just my 2c.

My '72 has balsa. I thought I had a soft spot but it was discovered after cutting top skin that it was only delamination and no rot etc anywhere..looked like brand new core. I dont know if there is room enough to get to underside from fuel tank area????. Drilling holes and filling epoxy is a way to go if you dont want to cut skin...just dont drill too deep!!!!
