This is not a bug but a change to eliminate differences with the boardgame

Ships with no hull now properly "surrender by striking" instead of sinking. So they will now also block line of fire.
There is however still a bug on them: if you board them, you will just lose your OBP (in the boardgame you can board struck ship and use the prize crew to fight melee from there, even if struck ships can't move or fire).
