Remove cut-off cap to inspect the wood, if intack let dry completely, using air and or fans, heater, etc. when completely dry. No get out your drill, with a stop, and start drilling holes in the wood, like a "pin-cushion"
Then order and get some Aero Marine epoxy, look for it on ebay and videos on youtube, "how to"
this stuff is a non-blush two part epoxy resin, you can add 10% (by weight or volume) Acetone to the mixed resin, creating a penetrating epoxy resin, mix up small batches at a time. Get a meat injector needle or large medical injector/needle and start injecting the same size holes you have drilled down into the wood, the keep injecting or pouring your penetrating epoxy resin until the wood is SATURATED with the resin......once cured it will be as harder than wood and will not absorb water. I have used Aero Marine reresin to restore a lots of damaged wood and to preserve new wood before I glass it into or over.
If wood is "dust" you may have to chisle/scrape out rotten wood and replace. Choice of material is a good question. If you go back with new wood pre-saturate/treat with the penetrating epoxy resin after you have cut and trimed new pieces, then glass over.
what do you stringers look like now ? lol do you know how much un cured poly was put on the woven glass in these boats ... man i took a hammer once my floor was off and hit the sides and they just buckled like plywood ... i would be worried about old glass breaking apart ... that is if you were doing the whole stringer /ribs.... just do some
research on these older supras .. you will find that foam / water saturated resin .. and more water ... lol
