Soft spot in fiberglass floor

[greenhornet73]

I have a 2’ diameter soft spot on the  back deck of my Sea Ray Laguna and wondering what it would cost to have something like this taken care of.  I believe the stringers are wood beneath but no access to get under there besides a 1’ access hole in the floor.  If anyone knows who does this kind of body work, I would appreciate any info.

I was able to look underneath the floor through an access hole and it isn’t the stringers. The fiberglass has delaminated from the middle layer that is sandwiched between two layers of fiberglass.  The soft area is about 1’x1’, do I have to cut the floor or can I fill it by injecting it with filler?

Find the water intrusion first . Might try googling Inject a dek to get real world reviews on it. Personally I would cut it out and replace the wood , inject a dek to me is a band aid . I go with the saying : fix it once the right way and be done with .

what about installing a hatch and use the area for storage.

I think I will end up cutting the floor out around the area and replacing the core with some sort of plywood or other sturdy material. I’m not crazy about the floor looking like a jigsaw puzzle but I think if I use some 3M white silicone sealant to seal it back in it won’t be too noticeable maybe.

After your done I would suggest going with Marine Mat deck carpet. Snaps in , easier to clean than SeaDek and less money.
