As a question to guys that have their surf wave very dialed on (Gibbs etc) how deep is the top of the surfgate that is deployed running underwater while underway? Or can the top corner of the gate be seen?

As another question - How about with ballast full and you are stationary? Where is your platform sitting and top of the gates sitting?

I have 2016 A20. My platform sits above water when not weighted. When all ballast+pnp are full, the platform is sunk under a couple inches of water. While underway (at surf speeds) the surf gate doesn't go down any further than normal, although it may be sunk more as the bow is way up in the air (have to stand at steering wheel to see over the bow). Your prop will be way lower than the surf gate so I'm not sure what you're after here. Surf gate swings out, not down. If you're worried about really shallow water while surfing, you probably shouldn't surf there. I don't know how to measure "depth of surf gate while underway" -- depth finder measures from where it's installed to bottom.

Question arises after getting a much more stretched out/lengthened wave after unloading ballast from the opposite side I am surfing (the side my surfgate is deployed) and essentially raising the tab up in the water. On my A22 with all tanks full (750's in back) mine run pretty deep under the water. I was wondering if the guys that have really dialed in their waves are similar or if theirs are close to or at the surface.

Oh, so you're saying how deep is it from the surface, now how much lower is it than the draft line.

The surfgate is designed to slow down the flow of water and the convergence point so that water flows under the surfgate and back up at a further point behind a boat thus making a wave. If your surfgate is too low in the water then water will flow over top of the gate, thus negating part of it's effect and you'll be left with a shortened and washy wave. I noticed this myself this weekend when I was running 825 rears full and wedge, but no extra bow bag on top of the seats like I normally do. This caused the rear of the boat and thus surfgate to run lower in the water and water was washing over the top and creating a washy wave without a good lip.

I pulled the wedge up and the wave cleaned up. If I had had my extra bow bag like I normally do or drained some from the opposite side this would have raised the surfgate out of the water, thus creating a cleaner wave. I really like the extra push the wedge provides so I'd say if you're running wedge and those 750s then you either need to add an extra bow bag up front to change the angle of the boat and thus the surfgate depth, or drop some weight out of the rear bags. Experiment with equal weight dropped or weight dropped only off the surfgate side and see what feels/looks better.

Appreciate the input and my own experimentation has yielded similar results. Basically by raising the wedge and listing the boat, by dumping ballast, the wave stretches but will loose push. Which at 6'5" 250lb I need all of that I can get. I Find myself riding a big jacked up wave basically way up near the platform.

To your point with bow weight - On top of the stock center tank and front pnp horseshoe bag I have an additional 200lb of lead in the nose. In order to help further I also, this winter, bought a 400lb sack to play around with between the front cushions and the walkway. It has helped.

I really think a huge part of my issue is the overall shape of the A22. It's cockpit sits further back than the T models and this its center "tipping point" sits further back as well. More weight is needed to get the front end to sit down if the rears are loaded.

The crux of my original question was in thinking about exactly what you described. What if my surf gate physically sat higher in the water line? With the shape of the A22 the gates ride pretty low in the water with ballast full. For ex with all bags loaded my platform and gates are fully submerged a couple of inches while stationary and at riding speed (11ish without it listed or weight dumped) water is absolutely washing over the top of the gates.

My thought was what if someone were to literally build a taller surfgate panel that sat higher in the water. Would this allow us to run bigger weight, getting the wave size benefit, while also getting the benefits of a more stretched wave with the gate sitting out of the water?
Thoughts?????

Buy this for your bow and ditch the 400lbs in the walkway. Or do both?

I have a 15 A22 and run wedge down, stock tanks, 600s in the rear, bow sac full, a 400 sac in the front walkway and 350 in lead bags that I move forward or back between reg and goofy wave. My platform will be sitting just about at the water line with two people in the boat and my wake and wave will both have a great shape, but if I stack more people in the boat, then I need to have people in the front or dump weight out of the rear, otherwise my wave gets washed out.

I think taller surf gates would help this and wonder why they aren't taller to begin with.

Didn't they raise them on later models than 14 and 15? This is my basic question posted about surfgate spray, I eliminate a lot of it by running 3 150's on one side of bow to create list to surf side and by reducing opposite rear sac. It works but then my surf side rub rail bow corner goes from 0-2" low mark above water to 6-10" high mark and if I was on a busy or windy lake this wouldn't work cause it would be one wave after another in the bow, but on a bayou with no traffic it works great , it lengthens the wave well BUT I lose some of that height I cherish from Opposite side rear sac deflation. I think I heard somewhere that there was a part to bolt on to top of surfgate to eliminate spray, eliminate the spray and wave cleans up nice. I run 850 rears 900 mushrooms bow full stock Wedge and the three 150's in a 14' A20

If they did raise them in 16 then I feel bad for the prev A22 owners as I feel mine ride really really low. In my head, since the surfgate just bolts on it could be an easy enough experiment to just cut some new taller gates, even out of wood, and bolt am up just to see what it accomplishes. My issue is I am building a house and at the same time have a hard deadline of a baby on the way Aug 1st. Figure what little time I have in this short season should be spent on the water not running experiments. I guess I just hopped someone had already run down this road??

What about a Suck Gate with surfgate? Anyone tried that combo yet?

Saw a 16 a24 this weekend and my spray is because mine are at a low angle to perpendicular and the new ones are more extreme to perpendicular at same height, so more bow weight should solve your problem without emptying opposite sac
