Looks bad

I am not an expert on hull damage but it looks to me like water got in at speed and just blew it apart.
Any signs the transom is flexing where it connects to the bottom of the hull?
The bunks of the trailer should extend beyond the transom.

i'm thinking a hard strike (log?) or grounding. If you look ahead of the damage you can see two black scuffs where it looks to have been hit by something. I would think if it were a blow out there would not be minor or secondary damage ahead of the blow out like the abrasion on the strake.

Whats the story? Yours? . . . . . ouch

(friends boat)
came off of lake,pulled boat out
of water(boat is dry staked)and noticed the damage.did not notice anything while running .boat is sitting on dry stack rack in picture and not trailer.
thank you for posting the picture
not sure on what to look for to see if boat was flexing.boat was in excellent condition,previous to this

friends boat,the lake(lake Erie) was rough,were running hard as always,but did not feel anything strange.black scuffs may be from tow motor at dry stack building.will take closer look at damage tonight

Any chance the it was hit by the front of the fork when they were driving underneath?

That seems the most reasonable way this could have happened...
