IIRC your hull is the same as my sunsport, minus the open bow. last year i was running 300LBS in the bow, 800LBS in the rear ski locker and another 800LBS on the surf side next to the dog house, plus what ever people were on the boat at the time. This made a very surf-able wave. Forum member Trayson has a sunsport and he was getting a very good wake last year. I actually just pm'ed him about his set up. this is what he wrote back:
my best setup was as follows:
370 tube sack under rear seat.
750 fat sack beside doghouse on floor
another 750 fat sack that is 1/2 to 3/4 full double stacked on top of the above, with as much of it in the rear seat as possible.
im going to try the set up this weekend and see how it works on my sunsport
