How to firm up surf wave?

[sbaird4000]

Spent yesterday on the water with a crew of 7 in our 2017 SAN 230. Rear hard tanks and 650 wakemakers were full, belly hard tank was at 3/4 full, speed was 10.8 MPH, NSS was 3-4 and the hydrogate was at 2. 2 adults were sitting in the bow, 2 adults sitting port side and 2 adults starboard with 1 surfing. The wave was fine just didn't have a very firm lip 6-10 feet from the boat, primarily where you would be looking to get some air. Any advice on how to firm up the top / lip of the wave would be greatly appreciate. Thanks, in advance.

Usually increasing speed helps firm up the wave for me.

Agree. 10.8 is pretty slow. Only the pros go that slow to make the course last longer for tricks. Try 11.2 - 11.5.

Thanks for the advice. The reason I go 10.8 is to increase the height of the wave. I have 500 pounds of leadwake in the mail. Maybe with the extra 500 pounds out back I’ll be able to increase the speed and maintain the same wave height with a firmer lip...

10.8 is not that slow in a 230, in a G23 that would be way slow, but not in the 230. what I found in my 230 was 10.8-11 and running the same settings as you posted so not really sure theres an issue with your settings. One thing I did was weight the surf side a couple hundred pounds heavier...…. Port side is pretty hard to get a really firm wave on those hulls, its just super clean. little bit firmer on the goofy side. That's the big difference between the G23 wave and the 230 is the Firmness.... The G is solid. 230 is cleaner.

For reference when I pull out my soulcraft to try and catch air I ride my G at 11.6-11.8, skim I ride 11.4

On my 2016 I have the manual hydrogate and turn it all the way off on the portside when surfing goofy as the wave is washy using the hydrogate. Without hydrogate I get a nice curl. I turn all the way on on the regular side as it has opposite effect on that side. I run 11.2.

So you aren't even filling the stock belly tank all the way and you plan to run 500 lbs of lead in the back with your 650's? I'm guessing you'll have a pretty good view of the sky as you're driving...

Lol! Keep in mind that I had 2 adults riding in the bow and I'm guessing that was a contributing factor to not needing a full belly ballast. I'm planning on having to fill the belly tank more to compensate for the additional weight in the rear. I also have a wake makers 500 pound bag under the bow seats if need be.

With your extra ballast and people you should have enough weight to make a steep wave. I would fill all available ballast increase speed to 11.3-11.5 and play with just the nss to increase your steepness. More speed will increase water pressure under the board so the wave will feel harder.

This is the advice I was looking for. Thank you, Nohlan!

I would add that your new 500 pounds needs to be spread on either side of your boat. Not in the rear. Space 300 on the port side and 200 on starboard. Spread it between the rear seat and driver’s/observer’s seat. See what that does.

I have found that tall does not necessarily mean more push. It’ is the MASS of water behind the face that seems to dictate push. On a tall wave with a peak you don’t seem to have that like you do with a more square shaped wave (ie, G23). For example, my buddies X23 has a tall/rampy/peaky and impressive looking wave but he complains that it does not have nearly as much push as my G23, which has a more square shape to it. Seem to go up steeply and then there is a square edge to it before it goes horizontal. I think it is that mass of water where this wave gets its push from.

That's exactly what I'm look for, a more solid and squared off edge that is better suited for tricks. Getting air in particular. My buddies LSV 23 has an immense wave but it's not nearly as steep as the wave of my 230. I received the 500 pounds from leadwake today and can't wait to start testing.

You don't think adding 300 in the rear port side locker below the 650 and 200 on the starboard side under that 650 is the way to go? I figured my 500 pound bag in the front would be sufficient counter balance.
