Chris craft 260, transom rebuild, twin to single conversion. Opinnions
Finally have time to start this rebuild, would be nice to hear some advice how to do this correctly. Plywood type? Epoxy? Polyester? Shape off new stringers? Need strenght for 70mph speed

I guess i am going with polyester, even the vinylester is 3 times the price off polyester here in Finland. Local fibreglass guy has mold for U-beam stringer, plan is to make the stringers from U-beam, twice as thick as the small sample in the picture.

Interesting with the U beams, just make sure you build up a layer below the U to spread the load as much as possible.
On a conventional type build, I would use 2 layers of 3/4" plywood for a structural location, giving you and area of 18 square inches (plus fillets) per lineal foot to spread the load.
The U looks to be about a 1/4" giving you 6 square inches per lineal foot, and only fillet on one side of each vertical. You mention twice as thick, so the layup, width or height?
Just something to ponder, unless you have addressed it already.

The 260 Stinger is an awesome hull, and I'm happy to see you putting the effort into one
