I saw something simular to that in Florida last year. It wasn't a Sailfish, but I won't name the manufacture.
Some manufactures are "glueing" the stringers to the hull. I forgot what kind of glue it is, metho.... something. Anyways, the boat I saw, the stringers detached from hull on both sides, and one of them, you could slide you hand under it
. This boat had stress cracks similar to the pictures here, and they ran the length of the boat, mostly on the liner, where the stringer had become a battering ram into the bottom of the liner, and stressed cracked it the whole length. Amazingly, there only a couple of minor stress cracks in the hull, on the outside, but on the inside, alot of the gelcoat had cracked away, and the bilge pump was choke with a lot of debris.
I am not sure you could pound a sailfish that hard, and not rip the t-top right out, and pound the occupants to death. Generally, they are pretty solid boats. I would pop an access plate, and see if the stringers are attached to the hull and the liner, and if there is any debris in the bilge. That kind of damage is going to start sheading stuff into the bilge.
