Rotten Stringer Advice Needed

I'm currently restoring a 22 Foot powerboat. I have the hull completely gutted including the fuel tank. The forward stringers (not engine bed stringers) have a few areas (5 inches by 5 inches) that are rotted. These stringers are made of what looks to be 3/4 inch plywood lightly covered by fiberglass. My plan is to apply a few more layers of biaxial fiberglass to the entire forward stringer structure to stiffen it up a little. Since these stringers do not support any hardware, do I really need to repair the rot or can I leave it alone and just let the glass handle the loads from the hull? I'll try and post pictures tomorrow.

Thanks

 

I have attached pictures above. The areas that I have circled are areas of rot. My plan is just to completely encapsulate the stringer system with two or three layers of glass. Does anybody have any suggestions?

Thanks

 

As read on another thread, "when in doubt grind it out !" You would be better of doing a good repair than a bad patch job at least you know that it is good then.

 

The only thing that I am worried about with removing all the stringers is the hull losing it's shape because of lack of support. How should I brace the hull if I do this?

 

As long as the hull is correctly and well supported, you will not need to brace it.

 

Currently the hull is sitting on a bunk trailer with three bunks on each side. Is the risk that the hull will sag or that the hull will buckle up?

 

Replace one stringer at a time. remove all rotted wood. any job worth doing is worth doing well.

 

replace everything

timber is cheap. labor is expensive, and much more if you do it twice.
