Holy Balls! I've never seen a boat ride another boats surf wake until now. Is that an older supra comp TS6M he's riding there?Quote:

This was the wave we setup last week. It was just me in the boat. I had 650 pounds in the rear starboard locker, the front was filled to 650 pounds, and I had (2) 550 pound bags behind the captains chairs... This is on an 09 21V. This is also my brother on essentially his first day of wakesurfing.
Questions:
1) For those that have been behind a lot of boats, how good is this wave?
2) Could the wave be made longer by using the same bags and adding 2-3 people in the bow?
The wave seemed very ridable for me when I went out on it. The thing I want is more length, but I'm not sure its really going to get much longer on this boat.
A knee high wave is considered small.
Thigh-high is medium.
Waist or above is a big wave.
Even my old 87 Sun can get a thigh high wave regularly, sometimes bigger. I run 500 in rear, 700 on rear floor, and 300 in bow.
That wave looks nice, but only about knee high. Without too much work you should be able to get it 6-8" taller. I would put more weight in the rear to start and if your wave it 'too steep' you will start to run into the swim platform. Then it's time to use a few hundred lbs only of bow weight, this will make the wave smaller but the pocket much longer. Nice video. Most people I know dont run much bow weight.
Thank you. I believe when I put the same ballasts in the boat, with the addition of 3 or 4 people in the corner, and a couple people in the front, I'll get it much better.
Mikey,
Is that all the weight you run?
I'm running 800 pounds in the rear all the way across, plus 500 up front in the bilge area center.
Then I add two 350# bags in the back corner...one on the floor next to the engine up against the rear seat and the other on top of lap overlapping onto the seat. Then I add one 350# up front in the bow on the surf side. I still don't seem to have the kind of wave it seems like I should have with all that weight.
A couple wave pictures...
IMO most people run too much bow weight. Your pocket is nice and long, but like you said you're not getting the height for some reason. My recommendation would be to start with the 800 in back, and the 2x350 bags in back. Then you will likely be 'using the brakes' a lot ie steep wave. Then add the 350 to the bow.
The reason I put mine in the hidden bow spot is that it keeps the bag close to the bow and pressed against the port hull. I would not recommend using more than 3-400lbs in front of the doghouse (excluding passengers). This is just imho, I dont claim to be 'the expert' or anything. :)
I have gone as high as 2000lbs plus 5 passengers but I find the best compromise as far as ease of handling, filling time, etc, to still give me the rockin wave I want is 1600lbs or so plus crew. Even if it's just the driver and mirror and me surfing, I usually stop at about 1600. Bigger crew is always nice though IF you can make em sit where you want em hehe!
This is probably my average wave, knee high when I am about 15-20' back in the pocket. Thigh when you get closer. That is also a compromise I make. The wave can be taller (by removing bow weight), but then it doesnt have as long a pocket for recoveries.

Here are some bigger waves from me:

OK, let me clarify a few things. The 800 in the back goes all the way across the boat...do you see a problem with that? What about the 500 in the bilge, should I drain that? I'm thinking maybe I should just put all the 350's in the back instead of putting any in front since I already have the 500 up front down in the bilge in front of the engine.
I also run my rear weight all across the back. IMHO it sinks the whole rear of the boat, making a taller wave. Then we make sure to add weight on the surf side too of course.
The bilge I am not sure about. Forward weight like that in newer boats where the tank is in the middle belly the just use like 100lbs. It sinks the bow a bunch. And out deep vee is real deep. If you get the weight off to one side, it has a different effect on the wave. I dunno lol. Tough to talk about. Try a sac on the bow once just on top the cushions. Keep it toward the port side. Also not much bow weight nessecary really. So maybe ditch the bilge sac for now.
Just start with rear weight untill you are getting close, then start messing with bow weight by itself. At least thats what I did. Again I dont want to try and sound like I am the expert or anything hehe
Next time we surf I'll drain the bilge weight and then add the 350 bags to the surf side. I'll start with the two in the back and go from there. I'll see how it does and report back.
I notice a lot of people's waves seem to curl around behind them and mine seems rather straight. Does that make a difference?
How fast do you normally go mikey?
Hmm well some people insist in driving in circles, maybe that could be what you are seeing? We drive straight and our wave is always straight as seen in this pic from previous post:
http://photos.wakeboarder.com/data/3...um/6090921.jpg
We go 10.5-11.5. I have a feeling you'll get it dialed soon heheh! :)
Thanks for all the info mikey. I'll see what happens next time we try it out.
Hey I'm always happy to chat - sharing shortens the learning curve for us all, right? Please let me know, too, what works best for you. I'm always willing to try other weight configurations too!
How many hulls does supra have?? I know from 82-96 mainly three with different cap configuarations. Has anyone created a weight deplacement diagrams of the most effective sacking placements with respect to hulls??
FRONT
PORT MID STAR MID
PORT REAR STAR REAR
EQUAL REAR
Can't get the diagram to look right. But if someone with better computer knowledge can create a template which we can enter our findings it would greatly improve the learning curve.
My boat...
We had the front gravity games bag in the back locker (roughly 900#), a 750# sac on the floor, a 750# sac on the seat, a 400# sac in the front locker, a 450# guy (red shirt), a pair of 250# guys, plus me (165#) and one other guy maybe about 150#. Sunk to the rub rail and the wave was sweet, it was as deep as it was tall...
Looks solid bird dog!! I usually have to run weight in the non-surfside if i put a ton of weight on the surfside in order to clean up the top of the wave.
The lean looks bada$$!!
I have probably surfed myself and others about 60 hours on the boat since March, so I've had a chance to really check out various configs on the 21V. There is absolutely a point of diminishing return. I have 650 pounds in the rear port lock, 650 in the front locker, then I fill up two 550 pounds, one directly behind the driver, then one on the floor.
Where the extra weight is nice is if you are surfing port side, in which extra weight is needed to offset the driver. I can definitely notice it then. But I cant really get it any bigger than when I load it as mentioned above on starboard. Looks about the same if I have that weight and 8 people in the boat, or that config and 1 person in the boat.
Agreed. I have come to the same conclusion after playing with mine for about a year now.Quote:

i know this is a thread revival of massive proportions, but most of the pics dont work for me. anyone have pics of a clean saltare or sunsport wave that is on the bigger size? on the hunt for either one of these two and trying to find pics for the wife. she doesnt want an older boat, but i dont want a payment or an i/o.
87SunSportMikeyD's picture on page 9 seems to work, his is an old Sunsport. '87 I believe?
Anyone have any ideas how to clean up the wake? I tried surfing behind my 20v yesterday, and it washed out really quickly. I had the 400lb bow sac full, and the surf side 400lb sac as well. Had 2 girls up front in the bow (one on surf side, one in the center), and had 4 others on surf side rear corner area. It washed out really quickly.. any ideas?
What was your speed? 10.5 to 11 is recommended. More weight, 400 isn't much for the back. Even with 4 people in the back you were probably only pushing 1100lbs.Quote:

You likely need more weight... but, on the flip side you could have too much weight. If you're putting too much weight on the surf side there's a chance you're pushing your swim platform into the water which could distort the wake. Again, most likely you need more weight, but just be wary of the opposite side of the coin.
No such thing as too much weight unless the rub rail is covered or water is coming over the stern. Keep sacking!
I think you're probably kidding, but regardless I need to address that further because I just thought of something I meant to say earlier.
If your prop is one that is meant for medium to high-end running (higher pitch) then if you put too much weight in the boat the prop could spin too fast at the slow speed causing a washed out surf wake. As you add more weight to your setup it is usually advantageous to reduce pitch of the prop so that your motor can push the weight efficiently and your wake isn't washed out.
I'm really only familiar with prop sizes for the older boats, so I don't know the specs of what the stock prop on your 20V would be or what to recommend, for that matter. That make sense to anybody else, or am I blowing smoke?
I'd think what you have typically read is 60/40 front to back but that is for wakeboarding. Surfing you will want as much weight in the rear corner as possible and then some front weight to level it out. In the 20v, I agree with you, I'd go with 750's in the rear.Quote:

Well, I got it to surf really well over the weekend. I just needed mroe weight as you all mentioned. I had a bunch of friends with me for the weekend, so we stacked them on the surf side and it kicked out a monster wave and it was really clean for a good 15 feet back or so. I had 10 people in the boat and filled all the ballast (except the non-surf side). That was some fun stuff. Now to get some bigger sac's...
Got a chance to play with the goofy side for my daughter over Memorial Day weekend. I was driving & this is the only decent pic taken by others, but she did finally get some decent free riding. Approximately 400 lbs in the bow, 750 surf sack on stbd chaise next to doghouse, 200 stbd rear bench, 400 in ski locker, and 6 post prom teenage crew mostly stbd. Not too bad for a 24 year old DD

holy crap thats an ugly wave. Big but ugly.
Yeah, 52ft boats dont respond well to ballast. We had 34 homeless people we were moving about and that was the best we could get.
i still want to surf it!
Wylie, did it look something like this?

homeless people huh? charity work?
