Supra Launch 21v Surf Ballast Help

I've got a 07 21v. I have tried to surf a couple of times this spring, but have not been very successful. I am running 650 in the rear surf side and 1180 center sac filled as full as the locker will allow (probably 900-1000). We are using a 5' 4" Ronix Cortez. I have never surfed before, so that is probably part of the problem. It just seems like the wave has no push behing it. I can't seem to get the rope to slack off completely.

Thanks
Jamie

You will need to add a bit more weight towards the rear on the side you are surfing. If your are on the port side put your wake plate all of the way up and try 10-11 mph.

We copied this guys SSV with the extra weight towards the back (except we did it on the port side) and it worked amazing. We used a 750# sac half up on the sundeck and half on the seat.

I have an '09 21v, so slightly different.

I have a 700 lb bag in the locker and then a 400 on the seat placed similarly to the picture above.
My center locker bag is only 750 and I'll put a 400 lb bag in the front pen. Human ballast goes to the surf side.

I have a custom 1300 lb bag on the way from Wakemakers for my locker.

Let's see some pictures, I have a new friend with a 21V were going to try to surf.

I will get some pics this weekend and post them.

Can we get a good wave from a 07 21V?

I think the guy in this clip as a 05' 21V. It is the same hull.

Finally got out to work on my surf setup on Tuesday afternoon. I left so quick that I forgot the vest, so not riding, only testing.
10.4MPH
650lbs in port locker
400lbs on top of port locker
900-1000lbs in center locker
250lbs on surf side of bow
140lbs driver
wakeplate 25%

No kids, so My wife and i could enjoy the evening. Can't beat the views at dusk.
Let me know what you think.

Very nice : )

2009 21V
Approximately 1700 lbs surf side. 750 lbs center. Speed 11.4, plate at 80%.
I'm first experimenting with skim style - pardon the poor skills. I think I need to slow it down for skim

Looks pretty good. You might not need the weight in the bow. Give it a try without it. A slight left turn will also clean the wake up a bit.

Here is a few pictures pulled out of a video from over the weekend.

I use this setup on my '07 Moomba LSV and it produces a nice wave.

10.7MPH
650lbs in port locker
550lbs on rear seats (across the back on portside)
550lbs on port seats
400lbs in center locker
200lbs in port bow (approx)
220lbs driver
wakeplate 25%
