thoughts on rz2 wave?

[Duncan]

THIS IS HUGE!! I WANT TO GET TO THIS!!

Just a big bag on the surf side seat in addition to (probable) custom sacks underneath. Get close to the same with lots of people on the surf side. Bags on the seats are a super pia.

Notice at about 3:50 the wave gets amazing and the rub rail is buried under water -- all those extra people in the boat from the Mastercraft. We surf like that sometimes but having the rub rail buried (rather than riding just at waterline) can be dicey with rollers. Also notice the wave with the guy on the platform is better.

I am willing to bet there is bow weight and they are riding 11mph+ given the pocket length.

You're right about the bow weight (400lb surfside)and the rub rail being buried. I stopped running the sac on the seat and started filling my fuel tank before each trip. If I kept my tank 1/3 to completely full I didn't need the sac on the seat. We switch sides often during the day and I HATE HATE HATE having sacs on the seats. I put over 500 hours on this boat in 2 years and the last season I really had this wave dialed in and no longer needed sacs on the seat. And I still had the same wave, actually it was better with less weight. With less weight the transition was smoother and the lip was much better for chop hops and floaters.

At first I though you were on Lake Austin, then I noticed you are on LBJ. Do you ever make it down to Lake Austin? I would be happy to hit the lake with you and help dial the wave in sometime. The RZ2 is very sensitive to weight and just tweaking your current setup can have a dramatic effect on your wave. But definitely get that front sac issue resolved, you have to use some weight up front to help bury the nose and displace more water.

cday76, you have a beautiful wave And your surf crew looks talented and motivated.

... The more you lean the boat the further up the wave the double lip will travel. ...

Here is my setup below that produces this wave. ... In the video I have a 400lbs sac on the seat, however after all these videos I ran without the 400 sac on the seat and got the same wave.

Speed 10.6-11.8
Taps 5
front 400 surfside
rear 250 factory hard tank
rear 1450 enzo that goes up under the seat.

Double lip comment spot on. 1450 Enzo sounds huge for RZ2 rear locker. How far up under seats does it extend? Our 1100 custom goes just past the rear edge of the flip up bench.

TAPS 5 seems way high. My wave gets too messy TAPS 4 or above. But maybe my 2009 and your 2011 have different relative settings. I use TAPS 3 for a wall surf style wave and TAPS 1-2 for newbies, slower speeds, or skim riders.

A passenger sitting on that surf side transom seat makes the wave golden (as you clearly know from your vid).

I have a pair of 400 in the bow but they only fill to about 300. I completely fill surf side and, so long as I have rub rail at water line lean, fill bow off-side about 1/3. If lots of people, I put one passenger in the bow surf side. Bow weight in the RZ2 is magic for pocket length (again, I know you know this!).

From vid, it looks like you do not run VX. One thing that will clean up your wave a lot is a flap. There are several useful surf flap threads here on TO. The flap is so cheap and so easy to install. It will smooth out most of that foam and spray at the top of the wave. Opinions widely vary, but I prefer the "floppy" mat for ease of install and less stress on platform mounts. Others really like the added smoothing of a fixed, downward facing flap. Either way, I think the flap needs to extend fully side to side and out past the rear of the platform when under way.

Nice video, riding and wave Chris! The rub-rail at or near the water line is the key in an RZ2. I have an '07 RZ2 and if I run bow weight, the wave collapses and adds nothing to the pocket so I don't run any at all. I honestly believe it is because my boat doesn't have factory ballast with the hard tanks and that since the weight isn't low enough in the hull, it doesn't need the bow weight. If I run with a full gas tank, it is better than a sac on the floor/seat. I usually fill up a vdrive sac and put it on the floor when there are only 3-4 people. If there are more than that, the wave is super tall.

Speed is what increases the pocket on my boat, I usually run 11.4 to 11.6 when I ride and 10.6 to 11.2 for everyone else. Occasionally I will ride my brother's LF custom quad with all 4 fins in and take the speed up into the 12's just for fun.

I have taken in to the SKI DOCK once to be fixed and it worked for a day maybe. Next day go to fill and it just fills for about 2-3 minutes then starts spitting water. I have no idea what the issue is but they will need to fix it under warranty. Have not made it down the Lake Austin in our new boat but def want to and would love some help figuring all this out.

"Double lip comment spot on. 1450 Enzo sounds huge for RZ2 rear locker. How far up under seats does it extend? Our 1100 custom goes just past the rear edge of the flip up bench."

The 1450 goes all the way to the front edge of the flip up seat. Almost into the front where the seat with the mirror flips up. It's HUGE and gets the job done.

"TAPS 5 seems way high. My wave gets too messy TAPS 4 or above. But maybe my 2009 and your 2011 have different relative settings. I use TAPS 3 for a wall surf style wave and TAPS 1-2 for newbies, slower speeds, or skim riders."

I used to run taps at 4, then we ran into Chase waiting for a film crew to arrive. He took a set behind my boat at 12 Mph and had me put the taps at 5. It made a small change to the wave that I liked and I kept it there. Taps at 5 also stayed clean when I removed the sac from the seat. It took forever to dial the boat in without having sacs on the seats and it's great to keep everything in the lockers with a great wave.

I would try the flap, however I sold the RZ2 recently and have a custom Z3 being built right now. I got the hull extension and I'm going to make people cringe when I start cutting up the hull extension. I've got a surf system in mind that will make the boat roll side to side after it's evenly weighted. Hoping it works, if not I'll be buying two hull extensions.

Here is the wave at 12 MPH, I still had the sac on the seat. However with a full tank of fuel I could get this exact wave without the sac. I stopped getting video for a while and don't have any good footage of the wave without the seat sac.

Good job on the edit, dig that video. Also the wave looks swell!

[Timmy!]

Awesome! Can't wait to see what you come up with.

Can't wait to see it!

X3 - can't wait to see. Also should be fun to see what you get out of a Z3, your RZ2 wave was pretty impressive!

There could be a few issues going on there ranging from clogged pumps, filters and possibly a problem with the pump. I've been to LBJ once and docked my boat in a cove with that nasty green/mossy/algae and it clogged up my water filter. It's possible that crap may have gotten into your system. Ski Dock is where I take my boat and they do a great job. If you let them know you are having the same problem they will definitely take care of you. Also if we're able to meet up on the lake I would be happy to take a look at that too.

I think you just follow ragboy's advice on that one. I've ridden behind that boat at the comp and I don't think you're getting much more out of it. Maybe you could but I don't know, it's pretty dang impressive. When the pro rider's ask you to dial it down, you know you are doing it right!

I think cday is contemplating something completely different than a surf-side weighted list setup. Even if it is not as optimized, it would be cool to see an even weight with "roll side to side" feature, especially if remotely deployable.

I am guessing massive wall from extra rear weight (which accounts for perception of speed) and shortened pocket from no bow weight and low speed.

I would also guess you have TAPS on 1-2 or else the tall wall no pocket would be unruly.

The wall is not massive IMO. The pocket seems pretty decent as well but, I have only surfed behind an A22 we owned and this wave is much better. I can take speed up to 10.2 and after that the wave looks terrible.

I run TAPS on 4. I can run it at 2 and it will mellow the wave some but not much. 5 and above and the wave starts looking very bad.

I have run the front surf side full which may help a little with wave length but, I'm not sure it makes a big difference. The key when I am surfing is offside weight. Push can feel a little weak and I can ask one of my boys (135lbs.) to move over to that side and and the push completely changes.

I'll try and get some video posted with the set-up we run. I'm all for any suggestions that could help get a better wave.
