Matt,
You have a great boat that will throw a great wave. But you are doing it wrong!
Lose the suck gate! It does not need it. That boat likes to lean!
1100# in the surf side locker, 500# under surf side seats, Center ballast full. Minimal bow weight (maybe 125 # and wearing a bikini), stack all your people on the surf side and back seat toward the surf side. Perfect pass at 10.7 to 11.2 (GPS speed).
Boom! Big and long wave with tons of push.... much more "playful".
But seriously.....lose the suckgate and slump that thing. Suckgates are for hulls that are not shaped for surfing.
