Disaster avert! Too little epoxy midships ended with the hull in 2 halves, liberal amount of epoxy for the second attempt only to find the mark one eyeball didn't quite have everything aligned as it should (oops!). A cut and shut operation followed with a new 6th section inserted.
Now for lots of filler to cover the dents in the foam, bit more sanding then hopefully it'll be ready for a nice coat of glass.
A slow burner of a project but I'll get there in the end (hopefully!)
