Surfing a Supra 21V - anybody have experience?

[Wax]

So I made a new friend while selling my boat, he had contacted me about buying my boat. He was looking for newer, but we started sharing boats we were finding (since I was also in the market) and became friends. He ended up buying a 06 21V about the same time I bought my LSV.

I went riding with him last weekend behind his Supra. The wakeboard wake was great, very similar to my old Launch. The surf wake however was terrible. I was shocked, but we could not get it to be even acceptable. We had 1200 under the bow, 750 in rear. We then added 650 on top of left seats. We then emptied the bow to about 400. None of it was good. Wakeplate wasn't working, but it was stuck at 50% and that's where I had it on my old Launch while surfing.

Anybody ever had a good experience surfing a 21V and can recommend a good setup? I've literally never been in a ski or wake boat that I couldn't make have a decent surf wake, including old boats from the 80s I've surfed before with a few fat sacks strewn about.

I would love to see what people say because I have an '08 21V and agree surfing on it is terrible. I haven't spent much time trying to fine tune it but I am very interested if anyone has thoughts.

The 21v just doesn't surf all that well from everything I've read or heard, but we make it work. The best we've found without piling a bunch of ppl in the boat is. 750 in the back left, 650 in the playpen,400 on the surf side seats,and about 150-200 lbs in the back right. I was a skeptic if adding weight to the opposite side but I did it while my brother was surfing and he said it added a little bit more push to the wake. It's hard to get the 21v to lean to one side, a 750 in the corner of my old lsv would really get the boat leaning. A 750 on one side of the 21v barely leans the boat over. I guess that's what makes it such a solid hull for wakeboarding. After everything we've tried the 21v still does not surf as well as our LSV did with a 750 on the surf side and 400 full in the ski locker.

I'd say cut back in the 1200 up front
I have '011 21v
I have fact 650 up front and 650 in left rear.
It's surf able to me.
Had a extra full boat this weekend and was better but also had bow full and that made wave long but not as big. I have extra 450 I keep saying ill make into a mobile bag but haven't had the time.
I run around 11mph and wake plate at 50%
This doesn't show greatest view but shows its rideable

I almost spent $10k more on a 21V instead of my LSV, this all makes me so glad I didn't lol.

bzub I tried also partially filling the right bag to no avail. I thought that maybe it needed more in the back.

04outback, your's looks maybe a little bigger than what we had and a little bit cleaner, but not much (as best as I can tell from a pic). Your wake looks washy just like the one we had. I couldn't get it to clean up, and at one point I had a very similar setup to what you run when we emptied a bunch of water out of the bow.

I'm tellin ya, It's just so crazy because I've never had this kind of trouble getting a surf-able wake. I should mention that I was able to surf it, but I'm a relatively experienced wakesurfer and can keep up with not much wake. Just because I could ride on the wave doesn't mean it was good, it was terrible and it still blows my mind! I love Supra, but this made me very upset :-?

[04OUTBACK]

No doubt the 21v hull isn't the most optimum surf hull. But it is surf able and can be optimized.
On suggestion is check speedo calibration to ensure speed

But. The 21v hull was designed to be a solid wake for Wakeboarding.

Just my 2 cents, last weekend we had 8 people out and with the stock G3 bags on the driver side rear locker and the center locker both full and the wakeplate all the way down we were able to get what I thought was an ok wave. You just have to tinker with it until it gets where you want it.

Do keep in mind that this boat was not designed entirely for surfing so there are some drawbacks if that is al that you want.

The hull geometry looks very similar to my 2000 Launch. I was able to get a pretty good surf wake out of that boat, not nearly as good as my LSV but significantly better than the 21V.

Seems like the boat wasn't designed for surfing at all if it's this hard to get a decent surf wake.

[KG's Supra24]

The 21v was possibly SC best wake hull until the SA came out. It was definitely in the top 3. It's a wake boat way before it's a surf boat.

With that being said, I have surfed a 21v and agree with most of the comments above. Try it without the bow weight and confirm the speed with a gps. An operable wake plate might be more help than you think, though.

[smitty75]

Attached are a couple pictures from surfing last weekend in our 2006 21v. It was our first attempt. This is with the 750 rear locker full, center half full, and wake plate at 50%. Nothing on the opposite side or in the bow. We also had 4 people in the boat. I found that at 11, the wake had plenty of push and we were able to stay in the pocket fairly easy. However, if the speed dropped below 10, it turned into complete wash. I need to upgrade my PP system to the drive by wire, so fluctuating speed is a problem right now.

I definitely don't think it's the best surf wake out there based on some of the videos I've seen, but plenty for us with just the installed bags. We haven't tried adding any extra weight, although I'm considering the 1,100 bag for the rear locker and maybe keeping an extra 400 to move around if necessary.

Your wave makes me want to buy 750's for both of my rear lockers hahahaha, who has some for sale?

[bzubke1]

Go for it! I've even thought of getting 2 of the 1100 gravity games center sacs for the rear lockers. I just don't think the 1100 surf sacs would fit all that well based on how my 750s don't quite fill all the way but that extra 300 pounds makes a big difference in cleaning up the wake if you don't have a few people to sit on the surf side.

[smitty75]

I'm not sure if our storage compartments are the same size or not as mine is a little older, but the 750 I stuck in mine seems to fit pretty good and allows me to fill to capacity. I do wish I would have got the 1,100 though, just was afraid it might cause damage to the boat due to the size.

[Wax]

On my buddy's 06 21V, no way you would fit a 1100 surf sac in it. His 750 filled the entire locker. I don't see how there's any spare volume to fit any more than the 750 in there, but if there is it would be nice to know!

[Cigars n scotch]

Yeah the 21 V hull is great for wakeboarding, which is what we do mostly but it would be nice to surf a little here and there. I definitely
think we need a new board, the one we have is too small for a wake that is not good for surfing. It's a Slaysh. like 4 foot something. Very small, but a cool board. Especially since I'd like to try surfing with my 2 yr old daughter. Guess we'll just keep trying different configs out. I want to replace the stock 400's in the rear for 750's too.

I need an endless supply of money!!! too many hobbies!

Can not complain one bit about my wakeboarding wake. It is great.

Now surfing, I may be wrong but i feel the more i stack my boat the better the surf wake feels but sucks to drive.

we run the back 750 full, 1200 in the belly full,i have an extra 500 lb of steel weight around the front, if i have less than 5 people we add a 400 lb sack on the rear deck (looks goofy have the bag on the sun deck but works) (I also though about going to 1100's in the rear compartments but with the 750's i can put 1 life jacket on top of the sac and any more and the compartment door starts to open.)
That might be it also i found the more i put in the back corner the better it does. if there is people sitting on the sun pad the wake is better than with them sitting in the seating area. can not do this to much we have a few warning for having people sitting on the sun deck.

we just started adding a 400 lb sac to the front to start adding more lenth to our wake and it seams to be working.

we start out at about 10.6 mph the more weight and people we add we have to speed up to clean the wake up fully load we seem to be more around 11.2.

I know it is not the best surf wake but i feel it is decent. We been having timing compations without the rope and we will go a good 4 to 5 minutes. Could be longer but the longer we ride the more adventursome we get.

The only other thing i notice that realy affects it is the lake depth. if it is less than 8 feet my wake sucks.

If it's less than 8 feet everyone's wake is horrible. It just flattens out to nothing. There's nowhere for displaced water to go. Gotta find the deep stuff.

Hi. My '08 21v has an awesome surf wake. I replaced the stock left rear ballast with an 1100lb bag. 1100 in center locker. 750lb on left rear seat. 400lbs on rear seat or put in floor and 400lb front playpen on left side. This gives me a TALL and long wake. But very tall. Def harder to learn on a taller wake for newbies and makes it challenging to start from the platform but I can. I'm only 116lbs though and I'm riding an inland surfer 4'3. Having said that I have taught many guys to ride ropeless behind my boat. I ride 10.8 speed and the guys ride around 11.2 on my boat. The bags do push the engine compartment walls in but wake makers makes reinforcement bars for this. Also be sure to have a good prop. Wake makers can help you with this. Also wake plate at 100%. With people on boat I might have to go to 50% or even add a bit of weight to right rear. Just play with it. Wake changes with weight, wind or busy lake water and adjustments are needed. Good learning.

All good advise,

For the newer riders I will put my wake plat all the way down so it flattens the wake and also sometimes lower my ballast level to knock my surf down.

I personally am not a fan of swim deck starts as its illegal in most areas, also people should learn deep water starts as when they ride other boats, those owners may not like swim deck starts and this is a dis-service to a rider only knowing how to start off a swim deck.

Well I only do platform starts and stops from my own boat and I've never met a newbie that would even try it. It would be rude to try that behind anyone else's boat. I guess my point was that with 3800lbs of ballast the 21v makes an awesome surf wave for those who have one and are trying to get a great wave. The Ronix shaper makes an awesome wave on it with 3400lbs evenly....1100 each rear and 1200 in center locker. Surfs up!

Hi. I run 1100lb bags on each rear side, 1200lb in center locker. add 400lb to seat side surfing if no extra people. Strap on the mission delta and you will have a massive wake that is long and tall. I have rode behind many new boats with surf gates 150K range and my 2008 supra is kicking their behinds.
