I need your help, my wave sucks....

[Branden967]

Hello Hayden, Could you PM that thumb pic to me, it loaded super small and I cant read it?

Holy crap.....3000 pounds! I get adding additional weight and I think I tried to accomplish that with the human element but guess I wasn't close. I didn't go big enough. Its hard for me to imagine more weight when the my rub rail are at the waterline. Just concerned about sinking....lol.

Also, you may or may not know this but at that elevation and +2800#, you will need an upgraded prop. Do you know what you have now? I'm at 3200 ft elevation and we would not be able to surf at that weight without our prop upgrade.

A final point of advice I would give; if this is your first time adding that much weight, because our hull has so little freeboard, you need your drivers to know/learn how to do the power-skid-turn when they pickup their riders. I still have intermediate drivers that struggle with it. I found a video on it when I first started looking into heavy weight but can't find it now. When the surfer falls out of the wave and you need to do pickup, it breaks down into 3 steps:

1.) Cut throttle to 1/3 (2seconds to do this). Lets the boat settle somewhat.
2.) Start a hard turn to startboard (1-2seconds to do this) If goofy riders you would go port.
3.) Cut throttle completely and wait 8-10seconds for stern of boat to "skid" around 180 degrees.

We've found that not doing this, especially on busy lake, but even when we're solo, will eventually get you water over the bow because you're so heavy loaded and have next to no freeboard. By doing it, you keep the boat almost perfectly inline with the wake you've been creating behind you upto that point and won't get any random waves coming across the bow from doing a circular pickup.

Great advise on the turn and pick up. Right now with the little weight Im apparently running, I can easily get water flooding in the bow. The wife figured out that one the hard way....
I did switch out my props, Im running the ACME 1617.

I would say more ballast as well......I'm running 900# in each rear locker, stock mid/front (400#) and IBS in the bow that probably fills to 450# in my 2013 OBV with a suck gate as well.

I bought a ‘08 OBV new in 2008 and owned it until 2018 when I bought my Max so I’m full of advice lol! Along with the suckgate and wakeplate at zero you need:

750’s in each rear locker
400lb sac on the surf side rear seat
300+lbs in the bow (in addition to the ski locker bag)
Speed 10-11

I guess I'll ad my 2 cents also.
Your post suggests you're running equal weight both sides and using the suck gate to create the surf wave. That's all good but, as others have mentioned you need more weight. But, furthermore, you mentioned you're at the level of rubrails and that is close. When I look at your wave, it looks clean, pretty, but very flat, that's why u do not have push. You need it to be more rampy. From your post I gather you do not have surf tabs, so U are not creating list. The more list, the rampier the wave in my experience, and you'll get more push. The flatter you run the boat, the flatter the wave, is what I have seen. More modern boats produce rampy waves because the tabs produce list, delayed convergence and as I recently learned here from one of the threads, it also produces Yaw.
Bu's get away with using gates because they are heavy and displace a lot more water, they do produce a long clean wave, like yours, but more volume, so more push. Waves on the Bu are very nice, long, mellow with nice lip and transition. I do believe the Bu's surf system empties ballast to produce some list though.
Without the benefit of a surf tab, and with limitation on how much more weight U can safely add, You need to list that boat in addition to adding more weight, safely.

Absolutely still need some list with the suckgate, here’s a pic showing how we had the 400lb’r on the bench:

I agree with everyone else that more displacement and more roll are needed. The double suck gate can give more ramp and push by forcing yaw, creating lower volume return on the surf side, deepening the pocket. By adjusting the placement of the suck gates, you can adjust the length and ramp of the wave.

Hi,

Having been on a journey from this wave

http://youtu.be/qzuIMQCs9Q0

To this one

With basically the same total weight in a 2015 Outback V what I can highlight is the importance of list.

In the first video I have two friends in the boat - both are heavier guys, in the second I have just my much lighter wife and son but the wave it 10 times better with less weight.

There are a few differences in weight placement but the one that has made the most difference and helped us achieve a repeatable foundation wave which we can tune for height vs length etc is list.

There are two quick and easy was you can test the effect of list on your wave without adding any lbs or USDs

1) Get your rider to cut out hard to the side on the rope and hold this position like a wakeboarder, this should list the boat a bit and you should see the wave get bigger and steeper

2) You can also get you surf side passengers to sit on the gunnels instead of the seats to see the effect of moving the same total weight a little bit further out - the effect should be the same but maybe not as instantly noticeable.

In the second video there are two set ups based on the same foundation of

650s in the rear lockers
400 ski locker
300 fatsac on bow seats
2 30-40lb bags of gravel that I move as far to the surf side as possible
Wife driving, son sitting on the surf side

This is our foundation wave, we can fine tune for length/height/clean face etc but as a fill up and go wave with barely any crew weight I am really happy with this, the push goes right back to the end of the rope.

Hope you get to try 1 or 2) and see the same results from adding list that we have

Well I gave it a whirl with everyone's advice and weight is definitely the key. We typically run the boat with my wife and our three smaller kids so not normally a lot of weight. I brought some bigger guys and kept moving them around the boat as my test ballasts and the wave had more push and we were really close to going rope-less. Im at a tough crossroads, I know I need the weight but the wife wont let me go crazy as storage is premium also.

Is the next step lead, lots and lots of lead?

[Stazi]

Yes. Lead for maximum density. Most weight for least amount of space.
