06 obv wakesurf ballast help

[kwm55ex]

I was wondering if anyone could help me with ballast set-up on my 06 obv for wakesurfing. My current setup, i fill the center bag full. I have wedge sacs in the back compartments, and fill only the left side. I believe the wedge sacs are 280 pounds a piece. I also have a 540 "big bag" that i put on the left side of the main lounge. I have a driver and two passengers that sit on the left side. I've found that the best speed is between 9 and 10 mph. I have the wakeplate at 1/2. The wake seems very short and tall. I would like to lengthen the pocket. I was thinking that I could swap the wedgs sac for a 400 lb bag, but not sure is that would be worth the upgrade. Any suggetions would be greatly appreciated.

The OBV will have a shorter, taller wave due to the hull design. Try a 750 in the rear locker, center full, maybe a 370lb tube sac under the port seats (cut out the cooler) and something in the bow. An IBS would be great, but first try one of your 280's or the 540. Put the wake plate at least 3/4 UP and try 10.0-10.5 mph.

Speed will lengthen the pocket as will putting the plate down. Work different cobos to get the optimal height & length.

I have the same hull as you and run the following:

750 in the rear locker, 750 in the main lounge area, 400 in the centre locker and an IBS (approximately 500lbs) up in the bow. Get about 2 or 3 adults in there as well and you have yourself a pretty decent wave as far as an older hull style OBV goes.

I think our speed is usually at 10.5 - 10.8mph and the wake plate at 3/4 of the way up.

Looks like I need to get some wieght! I think for starters, I'm going to upgrade the rear locker sac, keep the 540 sac, and get a sac for the bow. Thx for the help everyone.

So what should the wave look like?

Since we're new to wakesurfing it seems like the pocket is very small area, the wave is very steep and if you're not careful you can get enough speed to hit the swim platform or the back side of the boat. Guess we need to lengthen/widen the pocket?

Currently, we have a 750(full) in the rear, 750(halfish) port side center and a tube sac(300lb ish) up front and around 9.5-10mph..A little faster and a little wakeplate and more weight up front?


I have 02 LSV, guess that's the same hull as the OBV...

I never ran anything in the opposite the sirfside locker. I put people and the tube on the surf side and any extra up front. Try putting the wake plate down first, then add a little speed.

FWIW - I find I have to adjust my setup everytime we go out. I have a base starting point, then change speed, plate, ballast, people based on crew, water conditions, etc.

Yes, you need more weight up front and don't fill the opposite side rear at all. I find that this particualr hull likes to be on its side.

This is a video from last year of a friend of mine who I had just taught to surf. This isn't the best wave I have ever produced but it's not bad. In this scenario we have a 750 in the rear locker, maybe 500 in the seating area, center locker full and an IBS with approximately 500lbs & 3 adults totaling about 450lbs. Speed is 10.8 mph and the wakeplate at 3/4's up. (couple small kids in there too but not really significant)

Sorry, wasn't clear...All the weight is on the surf side, rear locker 750, the second 750 I have in the center playpen area, mostly on the surf side and a tube sac near the bow..
