G23 Surf Set Up

[Mahnal]

Anyone want to suggest how this would vary on a G25? It seems like all the same principles apply, but I have heard that the additional surface area of the G25 hurts the surf wake just a bit, and additional weight can help. But the only hard data I have is one person suggesting 1200 lbs of lead in a G25 versus the 800 gregmck mentions above? (I have 700 in the boat now, and that works well with similar settings, except I am using NCRS 3, NSS 4 (but not sure if that is best yet), at about 11.5 mph.

I had use of a G25 for six weeks. It does take additional weight to produce a great wave. I would suggest 300lbs in the bow. (150lbs under each bow seat). 300lbs under front passenger seat, 300lbs under each rear passenger seat for a total weight of 1200lbs. This assumes you run with a small crew. You can drop 100lbs under each middle and rear seats (less 300lbs) if you run with 4-5+ people.

Curious why NSS 4? I have never seen any advanced rider use NSS in any setting other than 0. Are you skim style? You will get a better wave at NCRS 2 or 3 with NSS at 0.

Gregg not to complicate this thread have you ever filled the left and right ballasts to only 50% vs 70% with 100 % in bow ballast to elongate and smooth out the wave for skim boarders learing surface 360s. Don't know if it would make the boat unsafe but curious if you had ever experimented with the settings I have stated.

I have never gone that low on rear ballast. But we don't skim so we don't experiment in that regard. We do host the Northwest Wake Surf Open competition. When the pros skimmers come to town for our competition they will often ride with us to practice. They basically tell us what settings they prefer. 70% L/R rear, 100% front, and NSS 0 NCRS 0 or 1 is the preferred setting for the pro skimmers. The only exception is Keenan. He likes a very steep wave.

Doesn’t the G23 already have the biggest And best wake in the industry? Why is all the extra weight needed? Isn’t the boat amazing as it comes from the factory?

In a nutshell , the extra weight (steel shot bags) enhances the wave

For most weekend warriors the stock G23 is a fantastic wave. Fill all ballast, set it at NSS 0 and NCRS 5 for surf and carve away. For skim less ballast say 70% and NCRS 0-2 is a great wave. But to reach your best level of performance and to do advanced tricks modifications to the boat weighting are almost necessary. These modifications are designed to flatten the wave while increasing the amount of push. In my opinion wave push (the ability of the wave to push the rider along) is most important because it is push that helps the rider stay on the wave when landing an imperfect trick. This helps progression because the rider has a greater chance to continue when they would otherwise lose the wave.

Gregg,

I'm the guy that asked where the diagram was posted on FB a couple weeks ago. I ended up only doing the 500# and got it in the boat on Monday using your recipe … and it works great! So thanks for putting the info out there. In regards to the extra 200# on port side … is this ONLY to counter prop torque … or does your crew favor port side riding? Visually … the wave on port side seems a little bigger than starboard now. In other words, do you relocate a bag or two for the goofy riders?

Prop torque.

Thanks. In competition one scores much higher by performing tricks on both sides of the boat. So we practice both sides of the boat equally and want the waves to be as similar as possible Goofy (starboard) same as Regular (port). The prop rotates counter clockwise (to the port side from the top of the prop) so this causes rotational torque on the starboard side (goofy) which makes the goofy wave much bigger than the regular wave. So by adding 200-300 lbs on the port side (under front passenger seat) the waves are more symmetrical in size. That said there are still times we will reduce the NCRS when riding goofy to flatten the wave even more because it is really tough to land high air tricks on that very steep wave. Just for fun here are a couple of slow motion shots of some pretty cool heel side tricks. These are really difficult to do without flattening the wave.

I have never seen the regular wave be bigger than the goofy side? Remember the port (regular) and starboard (goofy) sides are referenced when facing the bow of the boat.

Thanks for again for the info. I thought that was likely the case, but just wanted to be sure. I've been surfing for a long time and did a lot of experimenting on my last boat because it was a wake boat, but not a surf boat by nature. Just trying to minimize my time spent since you've likely exhausted most/all scenarios. I honestly didn't know if it was actually bigger or just the POV from the helm. I did ride the port wave heel side and there was a much improved difference for sure. We've put over 200 hours on our '18 since last July and it's typically just my 115# wife in the boat driving. And … rarely have more than one couple with us when we have guests … and they're all thin people. We recently had around 1000# of bodies and was blown away how much better it was … and why I became interested in the lead. As I mentioned, we've been surfing for a long time, but have only really seen a difference in my progression since we bought the G last year. Excited to see what this does for my progression.

That was some impressive air on the tweaked heel side btw!

200hr / year with just the two of you is a solid amount of practice! With such a light crew you would really benefit from another 300 lbs of lead (800 lb total). I often surf with just my son (160lbs) and my daughter (100lbs). I have found that 800lbs of lead was the sweet spot with such a small crew. I also fill the gas tank every time we go out. Best of luck!

My brother and I both liked the steep wave. But we will see what 0 does tomorrow. Default being 5/5, we just stared there and have made tweeks along the way. We ride a hyper lite shim, and a h/l landlock. I have a soul craft voodoo on the way.

For whatever reason (prop obviously) the 16+ G hull likes to have a couple hundred lbs more weight on the Port side when surfing Goofy. The counter weight produces a much smoother transition with a way bigger face. If theres more weight on the Goofy side the goofy wave is just a steep wall with hardly and face.

You are not comparing Apples to Apples when your talking about a 13-15 hull vs 16+ hull. The 13-15 produces a far less steep wave than the 16+ the earlier hulls can also handle more weight in the rear. I ran 600lb sacs in my rear compartments, 100 lead by garbage can and 300 lead in the bow.

I only ever ran nss 0 and ncrs 5
