ski locker is pretty deep and long, fat sac's ski locker sack is about 8 inches short. there is no locker underneath the sun pad, thats a 500# ballast tank. the mid ship locker is damn deep you can fit a good sized person in it. I do 725# in there. the bow underneath the play pen i fit two 440# sacs double barrel shotgun style, could (should) do 1000# triangle sac.
(also i put a 700# "under seat" sac standing narrow width up between the motor box and rear seat(tank).
