Hull repairs. Please help

[amarcil77]

I bought my 86 Bayliner last November. It is a work in progress. I am using the boat while doing the minor repairs. This fall is when the big projects are going to be done. I have been taking on water and finally found the cause. When someone screwed something to the floor they put several screws through the hull. What would be a good fix for this. So i can still use the boat this summer. I pulled up the carpet and couldn't find the screws. Someone put a double floor in it so I have to fix it from the bottom.

Marine tex for now. When you repair from the inside later some layers of fiberglass over the spot

lots of other question for this one - after you do as stated. THis winter you might find a bunch of bad wood underneath. Read the restoration forums about wet foam and bad stringers

I have been reading about it. I have made the decision that I am going to completely gut it and redo it all. I have realized the boat has been hacked together. After getting a weight and subtracting the trailer weight I am about 300 lbs above manufacturer spec weight. I think there is a lot of water soaked materials under the double floor the previous owner installed

ok cool you know what you are up against.

I paid a buddy to redo a floor for me (stringers good) and found he had done the same thing - and the screw heads were fiberglassed over on the new foor. I used my dremel to cut the screws, then gouged out the gel coat around the screw (and left a bit of the screw for the marine tex to have something to grab to.

Joe, he deserves to be favourably mentioned! One of the very few not denying that their boat will have to be gutted. Hopefully he's one of the few lucky ones who find it better underneath.....

Unfortunately, he's also in denial that its safe to use as is. I can't guarantee it ISN'T safe, but he can't guarantee it IS safe ether. And the odds are with me... There is no telling whats hidden below a deck over, but just decking over & running screws thru the hull are proof enough for me that there is likely LOTS wrong below deck. If its bad enough, it won't be known while underway until it goes wrong. When it does, there's no way to know how bad it'll go. Boat & boat resto safely

I am going to be gutting out my 88 Maxum this fall / spring time for a complete rebuild. I got a soft spot from everyone coming over the back from the swim platform. Might as well take care of it and I will should be set for another 25 or so years.

Sorry guys. I have been away. I know for a fact the boat is in desperate need of a gut and restore. I have been doing a lot of research on the restore part of it. In doing so I have read that the stringers just need a filler under the fiberglass wrap. They are mentioning fillers such as card board and Styrofoam. Is this true? I know I want to keep it as light as possible but that just seems shady. How would you attach the floor if you were to use such a soft material?

Those would be engineered stringers and they're very expensive to install, it takes twice maybe three times the material to layup engineered stringers as does wood reinforced stringers.

If it takes $1500 in materials to layup wooden stringers, it'll take $3000 or more to layup engineered stringers because you have to use at least twice as much resin and fiberglass, and that stuff is expensive.

Engineered stringers get their strength from multiple layers of fiberglass (4 or more), you can do wooden stringers with 2 layers.

Does any of this make sense to you now?

Oh ok. Then wood it is going to be. I just wanted to make it lighter so I don't have to worry about weight. The boat is only 16 ft, not like it is going to make that much of a difference. Once its done, I know it will be a lot lighter because the double floor and all the water saturated wood will be out of it. Thank you guys for your input. Once I start the remodel I will start a thread about that.
