Made a custom Wake Plate Extension for Goofy Riders

[mmandley]

As always I am looking for ways to improve my Goofy wave, wife rides goofy and it seems more and more of my crew does as well.

Anyone who owns a Moomba and rides Goofy knows how sensitive the wave can be. It will wash out really easy, its short compared to Regular, and No one can sit on the Offset side <port> in the boat with out messing up the wave.

I made a little wake plate extension. This only works on the Goofy side, the reason is, the prop rotation throws wash on the goofy side. This plate does not effect Regular at all.

I have only made Rev 1 of this plate, I am going to remove it this week, trim off the extra that hangs back from the factory plate, also I need to bend it up slightly more. I used .190 aluminum which I now know is over kill, this stuff is strong, and very hard to bend. I would suggest using 1/4" stock.

The length is 24x12 but it looks like I am going to trim 3 inches off and make it 24x9. I used 4 stainless bolts, lock washers, and nylon lock nuts to hold it on.

Like I said rev 1.

Testing. Ballast is all the same in all 3 videos. I had a video from LBC last year I wanted to use but its on a SD card at home and I wanted to get this idea out.

Ballast 1500 Star, Nothing on Offset, 500 center, 650 IBS, 400 on Bow seat driver side.

1st Video. No one on the Offset Side.
You can see how the Flow is tossing Wash over on the wave, also you can see how the wave just isn't super clean. Harder to tell with a rider in the wave but the wave is also Shorter.

This is a short Video, showing you we have several people sitting on the Offset side. We are NOT running Flow just regular Ballast weight listed above but we do have 10 people in the boat.

Last Video is the longest but shows the wave now with Flow engaged at the 2 setting. Wave is longer as you can see she is getting back in the wave.
I have more testing to do, more ballast configs to test to find the perfect mix now.

But as you can see the wave is very clean now and we can allow people to sit where ever they want.

I have a video I shot at Hagg last week showing 4 adults sitting on the Port Side, 1 guy in the middle, and only me and a 130lb girl sitting on Goofy and the wave was just as clean.

Here is the Regular wave for comparison, rope is the same length even though it looks like he is slightly farther back, I think the difference is this is a Go Pro Video VS the ones with Claudia are off my phone.

Here are the pics, Simple yet very effective I think.

Only covers half the wake plate. White is a protective film I didn't remove yet.

This is why I need Rev two, plate needs to be bent upward a little more to match Hull curve.

I think Millerda68 is going to make one on his LSV as well, so it will be interesting to see how it works on his hull as well.

Interested

[Flee27]

As I surf goofy I am very interested. Anyone up for a little education on how the prop wash effects the wave and how something like this the wave.

Fun to see peoples ideas.

Thanks

Great that you've moved forward on this. I bet you had some cool friends encouraging you to do this, huh? :-P

It's called an A-Plate (asymmetrical plate) and it's what Centurion has been doing on their boats to counteract propwash. Lots of threads on this at the Centurion Crew. Lots of success over there.

Good job Mike.

[blackcup]

def interested in this ... 80% of our crew rides goofy. I have always found the wave to be great but theres always room for improvement

" I used .190 aluminum which I now know is over kill, this stuff is strong, and very hard to bend. I would suggest using 1/4" stock. "


Do you mean 1/8" stock as 1/4" is gonna be thicker than what you used?

[cornrickey]

I find my goofy side is cleaner than my normal size but I'm interested in if this will effect the depth of the pocket.

Yes you are correct, 1/8th would be my next choice.

I did use Centurion as my idea platform.

It sucks to be goofy, glad I found this thread.

[rca]

Very interesting....

Oddly, my goofy wave is probably better than my regular wave. Not a bad thing since most of my crew, wife included, ride goofy. My regular wave tends to wash out way more than my goofy wave.

I think that's pretty typical of the lsv. I wonder if the wake would change on the regular side of the plate were on the other side.

[JoelFett]

What are you guys doing to get a goofy wave better than the reg? Im using 1010 lbs on STBD (750 + 260) and 500 tank w/ 500 IBS and flow and still barely get push. I was wireless behind 3 other boats over the past few weeks (granted, G25, MC X46 and Supra SC400 are fairly easy to go wireless, but still). Im getting the 1100 this week and hoping this helps, that will give me 1350 lbs STBD. But im really confused. Ridden a few diff boards, most success with slingshot space pickle, or Ronix Koal Longboard. Is it a board issue? A size issue? (6'0, 190) or just i suck and need to get better at balance?

I don't have an LSV, I have an XLV. but the missing link to getting more push on my boat was filling the non-surfside locker about 50%. That made all the difference in the world for me. That and ditching the OEM swim platform that was cutting into my wave and taking away energy from the wave. So a custom swim platform and not leaving the other locker empty = push for me.

Your results may vary, but it's something you can try for basically free with the non-surfside weight.

[newty]

On the LSV you don't want too much if any non surfside weight. 1100-1500 surf side and 1000 in the bow is what worked best for us.

[mmandley]

I think that's pretty typical of the lsv. I wonder if the wake would change on the regular side of the plate were on the other side.

I never found this to be true at all.

While I was able to get a nice goofy wave, it always took a lot more leaning and would wash out a lot faster then regular.

I was always able to pull a nice clean wave on regular.

As for the Plate, I Just don't see how it will help Regular wave at all, unless you have a reverse spinning prop which SC doesn't use.

All the plate is doing is NOT allowing the prop wash to splash up on the wake plate and out away from the swim deck. It just causes the wash from the prop to stay under the surface of the water. I think the reason why I can no have people sit on the Port side while surfing Goofy is due to the prop wash hitting that plate, and actually forming the wave sooner now or actually pushing the boat slightly over to the Startboard side more because its pushing directly off the extension. When under way the boat leans less due to its natural tendency to want to level out. On Regular the prop is turning the same direction as the wave so it will force the boat to roll more into the Port due to simple physics.

I'll say the only time I've had wash that affected my goofy wave was this weekend with bad water and too much weight on the port side. We only run goofy. 1100 stbd, center full, 650 in the bow, and depending on adult passengers I'll fill up one of my original stock bags to to fit where the cooler was (probably 40-50%). All of this with flow in 2nd position. I also run at 11.5, anything slower and I was nearly in the boat. Next time we go out though, I might move one of my original factory sacks to the bow to see what that does.

This pic was taken with 2 other adults and 3 additional kids in the boat, and they were sitting all over the place.

Hey, I like that board.

[rca]

I don't have the flow, so take that into account. We have a 2011 LSV. Our goofy wave setup is 1100s in the rear pretty much as full as they will go, 500 center full, 650 IBS full. Depending on how many people are in the boat I might have a couple of 350s on the seats on the starboard side. No weight at all on the port side for goofy setup. My wife rides a skim board at about 10mph and loves this setup. Plenty of push and a big wave.

[5:00]

I ride goofy but I am one of only two (including my youngest kid at 13 y.o.) that ride that way including friends and family. Last year I started learning to ride normal and found it pretty easy to do for the most part. I got tired of switching so much plus the relatively crappy wake I got on the goofy side. I will try Tryson's idea with the 50% on port and see what happens.

Good job Mike.

Was my thoughts exactly when i read the thread. Was going to direct you over to the CCC for some tips. Think you're on to a good start and would imagine it'll clean it up alot once you get it perfected.

[saskie99]

My wave is way better on the goofy side than the regular side. I went ahead and build a ghetto gate for my boat out of some wood and now I can fill the whole ballast system, 650 bow, 500 mid, 750 in each cornerhttp://images.tapatalk-cdn.com/15/07/15/278c68a8ddaf3b3a96cd6d9984c2cd01.jpghttp://images.tapatalk-cdn.com/15/07/15/f36ee280f4226ed307152cfa0374a8ad.jpg

[saskyrider]

Damn Saskie that is a deadly wave!!!

Yes, just ordered the plate last night, went with 1/8th to give it a try. Also working on building a gate modeled after some of the other posts here.

[millerda68]

My attempt at the extension off the wake plate was a fail. Caught a mud bar at Hagg and folded the extension over. I never got to try it on the goofy side.

I did slap together a ghetto gate. We tried just loading up the surf side and found that the pocket on the wake lengthened, but definitely lacked push. 1100 in the rear locker. 400 in the center locker. 6 adults on board stacked on surf side and 2 in the bow. From there I filled the opposite side and ran even weight. Huge difference running with the even weight. The wake had better push and pocket was lengthened over running without the gate.

The gate was just a cluge of what I saw posted on several different posts here. Mostly following what Trayson has done and posted here for his XLV.

Steering with the gate is not a huge ordeal. It is simple to put on and remove. I am hoping to get to play with it a bit more over Labor Day weekend.

[jstenger]

Just some info. The wakeplates on the 2016's are 22" wide, 16" long measured from the hinge pivot point, and at least a 1/4" thick. I am thinking about using those measurements plus the additional wing.

[Flee27]

Update on this topic. There was some talk about what thickness would work. I had some 6061 1/8" and decided to give it a try. After it was installed it seemed a little flimsy but decided to give it a try. Put the boat in water and drove the 5 minute ride to our house. Went out a little later and rode around for about 20 minutes (no ballast) and then put the boat up. Didn't hit anything and not sure when is happened but can definitely say that 1/8" 6061 is not thick enough.
