Nice! Looks great! Man I wish the season wasn't done so early up here in AB.

Pic of the same wave without rider- my favorite part is the steep section/curl right in front of the whitewater pretty far back-

[zeckto13]

I guess maybe it ended up filling more vertical around the box. Helped keep the 750 on the seat too. Will take a pic next time.

Ya I hear ya. I was skeptical too but ended up putting my 750 there which is also 20 inch wide and was surprised how it still filled out nicely around the engine box. I actually filled it all the way as much as I could. Food for thought.

I wanted to put the 475 behind the engine, but it just seems like it would not fit there- the bag is 20" wide, and there is at most like 12" between the engine box and back seat.

[zeckto13]

Looks good! Thanks for posting. I think the belly weight definitely cleans up the top face. Did you try swapping the 475 with the 275? Compared to your video earlier of your buddy, looks like a comparable wake with less list so that's good...helps with the driving/safety.

Also, Zeckto13: How do you fit a 750lb bag on floor behind the engine?....it seems like even my 475 would not really fit back there....

[Tom351]

Here is mine with the following setup- still listed, but not as much....(475lb offset instead of 800lb)
Same gate with the edge "winglets" added- not sure if they helped or not...
800lbs in rear trunk
370lbs in belly ski locker
800lbs on rear seat (centered)
275lbs behind engine (centered)
475lbs next to engine (on surf side obviously)
1 person in boat
(I wanted to try the gate higher but did not have a good chance to swap faces... will next time)
10.5MPH on GPS

Wave seemed steeper and bigger (makes sense as the weight is now farther back in boat compared to last time)-
Was able to ride the wakesurf board for good amounts of time - but still prefereed my 6'-0" ocean board because it let me drift a lot farther back and still able to recover.
Boat was more enjoyable to drive with "less list" and weight farther aft..

Yup all his weight was in the back, mine as well. Should respond well I think if you switch as mentioned. Could even put the 475 on the floor behind engine and the 800 on the seat supported a bit by the 475. Let us know how it turns out. I will probably buy another 370 tube sac and put in the belly ski locker.

Also, it sounds like he has ALL of his weight in the back- (mine never liked bow weight for surfing- every time I have tried I moved it to back). I do have 370 in front of engine (in belly locker) and an 800 along side of engine- so that shifts things forward a little bit....wondering how mine would be with that 800 moved from next to engine to behind engine....then I could move the 275 that currently lives behind engine over to the surf side...Then I bet my gate would be too low, but I can quickly swap the "face" of it with a cordless drill to an old one that can be mounted higher.

[Tom351]

Ya, I have the fly high tube sac and agree it fits perfect on top of the trunk floor/tanks.

No, I was talking about the front ski locker....below the floor next to driver seat... I have the 370lb bag in there, and the impeller pump is mounted in there as well.

[zeckto13]

I have the stock ballast. Yes, they are below the rear locker floor. They are also only 400lbs total (200ea). Ya, I have the fly high tube sac and agree it fits perfect on top of the trunk floor/tanks. That's why I'm not sure how he got another 350lbs in there if he's got the stock tanks. Guess maybe I need to pull my tanks and put a 800 bag like you beneath the floor. Someday project...

Yep, when he says "500lbs - hard tanks full" is that all below the trunk? I'm not sure where the hard tanks are since my boat never had them....Side note: a FlyHigh 370 is a perfect fit in the ski locker- I have that and my 800lb trunk bag both plumbed to a reversible pump...so I can at least get the first 1100ish lbs in and out easily.

[zeckto13]

Ya looks good. Now that I look closer you can tell he has the bags slightly to port side,so there is a tiny bit of list I guess. I was nervous to fill my seat bag all the way full but so tempting as his wave looks good. He has another 400 lbs in the rear locker over the 770lb I had as well. Not sure how he got that much weight back there unless he pulled his tanks. If I had added another 400lbs in the rear I probably would have been really close to the rub rail at idle!

I found another vid on YouTube of a guy with an Air and a mission delta who gets a decent wave as well not listing but uses a tonne of weight. I think our boats do like to be listed but I'm happy with my results above. Will just add a little bow weight to clean up the top, or am going to extend the height of my gate by 2 inches so that it is 11 inches tall like the Ronix shaper. Right now my gate is about 3 inches or so below the waterline when weighted. I think that may clean the wave up a bit more instead of bow weight. Here's the vid of the other guy I mentioned. https://youtu.be/5EvO1Rq44hg

wow, that is a nice wake.. and with about the same total ballast as I run....I will try mine balanced for sure.
