Re: fibreglassing advice
Last time I saw something like that, it was coming out of the roof on a sailboat with a plywood cored roof with moisture penetration into the core. Are you sure the floor sections of your boat do not have plywood core sections, over which the builder fibreglassed?
This would be a typical construction method for a home built dinghy.
So it looks like you have major water penetration into that core, and extensive rot. If I am right, I am sorry to report that your dinghy might be scrap.
However, you can check by cutting away one of the sections that is oozing, and see if there is wet wood at the core. Here there is no substiture for getting out the angle-grinder (with dust mask!) and exploring what is going on.
