Thanks very much for all the input. You guys are something else!

Well, I think I know why and what happened. Thankfully it doesn't look too extensive. Boy, was I thankful.

I cut the bottom out of the stb storage container to access the area above the crack. At first look, all was perfect, but on closer inspection, I found (1)the crack is entirely under the stringer (2) a small area of broken fibers in the woven roving in the bend where it attaches the bottom of the stringer to hull, about 2 inches fwd of the crack (3) the stringers are not symmetrical. The port stringer looks like it was pushed up against the vertical part of the inside strake and glassed in place. That looks right and should make it very strong. The stb stringer is attached at least an inch inboard of that, which would create lots of space between strake, stringer, hull, etc and maybe weakness in the hull under the stringer. With the stringer slightly out of place, the strake is basicly unsupported. Assuming the stringer is hollow, I can see how a compression fracture might occur.
Looks like grind out the bad glass, attach the stringer to the hull more strongly and do something inside/underneath the stringer, not sure what. Fill it with poured foam maybe? Since the entire stringer can't be filled without taking the boat apart, would that create hard spots at the end of where the foam goes?

Any other suggestions?

Thanks again

O yeah, the aft end of my stringers are hollow. I can't tell about the forward sections.
