Direct Drive Surf Report - 99 Sport/Air

[zeckto13]

I have a Sumo Long 800 in the trunk, a 750 sac behind the engine (found on ebay, it's like 20 x 20 x 65 no idea on type), and 300 in ski locker all tied to individual reversible pumps. Plus a lead wake or two. All weight is in rear, shifted to surf side. I usually manually fill an extra 200-300 on the rear seat on surf side to give the boat a little lean. I don't list the boat very much, it's pretty much even with a bias towards surf side.

Here is the shaper I copied, I get it as far back and below water line as possible. I imagine a shaper lower in the water and further back will lengthen the wave as others have posted. Speed is variable for us as we surf in a moving body of water. I have GPS PP and tend to go a little on the slower side, maybe 9.5 - 10.5. The Sport is very finicky, but we surf in deep water 30+ feet, start off slow and avoiding getting on plane, turning the boat (right a little for goofy) a little helps shape it even more, etc...

We also wakeboard quite a bit and throw another 200-300 in the nose to help balance out the weight. These boats do like their rear weight...

Also propped up with an acme 1868. Cuts through like butter...

Nice wakeboarding pic! I'm too old for that now. Hah. I also started out with a Mission Delta style shaper. Then made one like Toms/ the Ronix shaper. Had improvement with wake divergence and curve in the wave to give a better and longer pocket. Going to make mine a bit wider as mentioned in the thread come spring. Sounds like we're running close the same weight setup but I need to add 300lbs to the ski locker, on the to do list. Post some vids if you get a chance experimenting with the wave. Glad to see another DD have success surfing.

Nice wave Glassywaters! I was in about 10-12 feet of water last time out (pics above) do you see a big difference when getting into the deeper water? Trying to decide if it would be worth it for me to drive to a deeper spot in my local lake.

Glassywaters, I see your a fellow goofy rider. See post number 50 of my wave on a 2000 Air DD (same boat as sport). Your wave looks good. What's your setup with the 2000lbs.? Speed? Shaper type? PLT Nautique

Really nice looking wave. Best I've seen with a sport nautique. Do you have any issues with keeping the gate underwater and listing the boat? Just to add to the thread. Here is my 99 sport. I have three reversible pumps and about 2,000 lbs total with a homemade gate. We still need some more tweaking...

Got out again this weekend- wake felt really good, and was totally rideable with the smaller wakesurf board....nothing changed from last except that I made sure to get every bag totally full....

Looks really good!! Nice and long with the curl. So jealous. All I do is watch ski/surf vids all winter.

Nope, no issues.....the only thing is that if the driver is aggressive and causes perfect pass to overshoot the speed (10.5mph) and we get some pretty serious roostertail/spray into the boat at about 12mph before PP settles the speed down to 10.5mph

Ha, yeah, you almost ate the 6ball!

[zeckto13]

Speaking of slalom...check this out...reallllyyyy wanted 6 ball. Sorry for the tangent. Couldn't resist

[Tom351]

Yeah, I've been wondering if a larger face would help- don't feel too bad about the 8 months- I bruised my sternum slalom skiing that last time out, so my season may be done as well.....

[zeckto13]

Thanks. I think I'm gonna build the next one at 19" long by 11" high. My last one is 9" high. 11x19 is really close to the Ronix size i think. Will post results in 8 months...hah.

Yep- pic below- 8.5" high X 11" wide- 45degrees- shown next to other gate for reference .. Also, our lake is down about 3' so was only surfing in 10-12foot depth instead of 13-15'..... So maybe the wave would have been better this time if we had the deeper water.

[zeckto13]

Got back out this past weekend- used same ballast config as before, but swapped gate face to one that could be run higher (without extension to reach into step)- wake seemed about the same....pic at 10.5mph riding ocean surfboard- my wakesurf board worked much better at about 9.5mph.

Good to know. Wave looks really good! Got a pic of the different gate? Gonna be 8 months till I get out again...ugh.
