Another DIY NSS project

[Yiger]

My assumption is that the extension on the bottom provides a bit of "lift" to that side of the boat, which helps drive the opposite side down and helps the wake a bit more.

This gave me some ideas for my 200V so I went out surfing today and watched the water flow off the starboard transom. I think the 200V could get away with just the sideward extension if the boat is still ballasted off balance (assuming you are correct that the bottom extension basically lifts that side of the boat). Obviously using off-center ballast and a sideward-only plate eliminates a major attribute of the NSS, but it still might improve the overall wake. Just a thought anyway. Of course given the notched transom of the 200V, something like Malibu's system might actually work best.

Ok, I had been all talk.
Total cost was $20 of cutting boards and maybe $20 of stainless hardware. All cut with a jigsaw, dremel, and files. I could easily re-make this a bit neater and keep it manual, but winter is here and I want to go all out, but if you were thinking about trying to do something like this, it can be done without any holes in your boat or fancy tools.

I'm sure I am forgetting something, so ask away. This project will now consume me for the entire winter.

I've been just like you, all talk, until now...... I've wanted to figure out a way to test a DIYNSS similar system on my 06 210.
This is the ticket brother! I'm going to use your advice for a mock up / test setup! My plan after I can test is to laser cut 1/4" thk 316 ss for the plates. I just didn't want to drill holes in the transom until I was sure it worked. This will consume my winter now. What is the model number on the actuator that you are using? Thanks for posting your progress! I hate having to list the boat to surf. Mine drives like sh** when surfing on the starboard side. I typically run the same amount of weight when I wakeboard as I do when we surf, just move it around in the boat, about 3500 lbs total. Not having to move the sacs around would be AWESOME!!!!!

mbaumet, please keep us posted of your progress as I know myself and many other legacy 210 owners will be interested in this same thing.

After seeing supra come out with their swell surf system last week, I'm beginning to wonder if oversized trim tabs may achieve the same affect..... I looked at the back of my boat and I'm not sure how much effect the portion that comes out to the side will have. Our hull taperes towards the transom.

I will have to make a bunch of test pieces I think to see what setup has to most effect. The boat shows are right around the corner! I'll be the guy with a tape measure checking out the NSS , the surf gate and the swell. Haha.

That does look interesting... being able to shape the wave a bit and then switch in under 2 seconds. With the NSS design and the Lenco tabs, they are 6 seconds for full travel, so a switch would take at least 6 seconds. The tabs seem an "easy" way to go, but it may have a lot to do with running surfaces, etc, so you would have to be willing to play with it, which would take drilling holes.

As far as the taper, the SV hull tapers too, and it still has a good effect. I'm just not sure how you would adjust the steepness of the wave as much with NSS. I think on the G, they use the NCRS to do that, which is just a big middle trim-tab and all I have is hydro-gate which doesn't give you as much effect.

My plan after I can test is to laser cut 1/4" thk 316 ss for the plates. I just didn't want to drill holes in the transom until I was sure it worked.

I don't think you need to go with 1/4", I would say that 1/8" is plenty strong... unless you do the back plate at 1/4 so you have more to bolt/thread into. If you build a big enough plate that just bolts up to your swim platform, you could mount all kinds of different trim tabs or sliding plates to it for the experiment phase... maybe that would be fun.

As far as the actuators, I was planning to use the Lenco 101 XDS "Short" so they fit under the swim deck. That is what defines the 2.25 extension that I can get.

Great job Doug!
Now you got me thinking about my 220...
I'm looking forward to seeing your setup in action next season

Looks awesome Doug!

After stopping at my local dealer and really looking at the NSS on the G's I've begun progress on an NSS for my 06 210. I had planned on 1/4 for the baseplate and 1/8 for everything else. I have my actuators ordered. Materials are almost ready to go to the laser cutter. Couple more final measurements of the transom need to be taken. Just need to make one more 45 minute trip to the storage unit at the lake where the boat is.

When you get a chance can you take pictures of the template or shape of what you plan to do on the transom? I'm just looking at the transom of my 05 SAN and it looks like there is minimal surface area to work with as far as installing plates. I am strongly considering this on my boat but I am having a hard time visualizing it.

These don't have dimensions but should give a pretty good idea. I still haven't made it to the storage unit to finalize measurements, but what I've got here is pretty close to how the final one will look. message me if you want more details.

DIY NSS on 05 SV-211

I just completed testing on my DIY NSS. Thanks to dfoster for the inspiration and source for materials. Unfortunately my local Walmart's HDPE cutting boards must be weaker than yours. My board broke away after about 30 min. The wake was awesome while it lasted. Here is my setup. 05 SV-211. 400 lbs in port locker. 400 lbs in starboard locker. 350 lbs in center locker. 800 lbs across back seat. NSS deployed on starboard side 2".

I've been busy at work and haven't been keeping people up to date on my progress either... but my Walmart cutting board failed as well. It cracked off right at one of my corners, so I figured I must have made a sloppy cut, but it probably just can't handle the stress over time. It was working fine for a bit, but then I tank busted and really loaded the boat up and BAM. Suddenly the wake was no good... and then my daughter saw the plate floating in our wake!

I have my Lenco actuators in, and have built a controller with an Arduino board that will turn them on/off and allow me to adjust the distance they extend. I'm now trying to find the time to actually draw things up to get plates cut. Have you done that yet? Want to share drawings and I can help with the controller? I'm better at the electronics than the drawing. Honestly, I'm a hack... but hey, it gets built.

Let me know if you want to work together on the drawings and getting plates cut. If we can get one set up for an SV, we can share that with the group... or if there is someone else with an SV that is good at CAD, drop me a message and we can work things out.

Doug, made a design similar to yours and hope I can get pics to post here. Wave shaping has been awesome. Made my base plates out of 1/2" HDPE and the slide plate of 3/8". Made templates, prototypes ect,,, and final models after some trial and error but we have been super stoked by the results. Can adjust the length of the wave, shape ect,,,just by moving plate out 1-1/2" for skim boards or full 3-3 1/2" out for surf style boards. Every single rider this year has said our wave has more push and is longer or better shape in general for riding. We deal w a lot of current in the river we ride in so have to play w speed some but so far very happy w results.

[h2ojunkie]

More pics and surf wave. Wife on the Goofy side, friends wife on regular side. Sorry for pic quality. We will play w speed and ballast rear ratio,but right now, about 70/30, 65/35 rear ballast ratio depending on crew load. Front and center tanks full w 50lb lead and sometimes crew body or two up front. All these pics had no one in bow area this time out.

[jtryon]

that setup looks awesome. where did you get your hdpe?
