I usually fill the belly ballast and the passenger rear tank. I add a 500lb sack in the passenger rear ski locker. I then put a 500lb sack on the side passenger seat and a 500lb sack across the back seat. This year, I'm going to buy one of those 1100lb monster L shaped surf sacs from Fly High that will fit securely across the back seat and the passenger seat and won't fall off because of its shape. (I can get a few of these for a good price right now through a local dealer if anyone's interested). I use the hydrogate to tweak the wave and pull at around 10-11 mph.
The surf wave is nice behind the 230. However, I'm more of a beer and chicken wing eating surfer than a hard core shuvit throwing surfer.
Here's a few pics.
