Here's some pics of the interior:
3 sacs surrounding the engine compartment, plus 2-300lbs. in the front. Monster tower w/racks gets the boards out of the way.
You can also put just two sacs on either side of the engine and get a REALLY nice wake...
And who cares about space when you get a wake like this?!?!?! With 2000lbs. and the right prop, you won't come anywhere close to beating this wake at this price (or at a much higher price for that matter).
