Two things: one brute force, the other a more interesting work-in-progress
Brute Force: We have 1100# sacs in each locker, 900# sac on floor, stock tube sac in the floor, and a 540# sac up front. Fill the 1100# sac on surf side, and move the 540# sac to surf side front seat. We have the wakemakers x-link system so can switch sides in 5-10 minutes. The 900# sac sits on floor in front of the back seat, so really just makes a nice big sitting area. Bowfiller cushion makes it pretty easy to roll the 540# side-to-side.
Goofy wake is very good, regular wake is good, will never be as good as a deep-V hull.
More interesting work-in-progress: Malibu's surfgate is very interesting because it "yaws" the hull instead of just pushing down on a corner, so I am toying with a manual fin similar to all the threads on the malibu and centurion sites.
First attempt looked just like surfgate. I worked VERY well; no more 900# sac on the floor, replicated my goofy wake, and my regular wake was the best ever. Downside, there was a lot of drag so engine ran 500 RPMs faster than usual. In addition, the regular side wake required tons of oversteering, so had to physically hold the wheel in place.
Second attempt was very different. Instead of sticking out the side, the second fin was narrow and deep. Tried it yesterday for the first time and it is VERY promising. Wake looks very good on both sides, and much less drag so no more "steering issue" on the regular side. Have not surfed it yet, so idea if the wave has any push.
More info later, probably in a new thread.
