heres a picture of a blizzard kit boat I built a awhile back and how the turn fin is mounted on it the predator plans have a spar and turn fin pattern to go by
Also here is what a Feigao (if i remember right 7s) and cooling jacket look like in the hull not a ton of extra room side to side with the cooler and the predator is the same hull as a blizzard just has a couple extra inches added to the length
