XLV custom Surf platform.

[trayson]

So, I've been finding that my platform is cutting into my surf wave and the lip on the bottom is robbing me of push. I had the same problem on my Supra and made a custom platform for it.

This time I had more flexibility as there were only 2 platform brackets to deal with. I chose to make it out of black 3/4" HDPE. I was able to source some for $130 shipped. I then ordered some royal blue diamondd cut Hydroturf for padding. ($40 + $18 shipping for supposedly B stock but aside from some smudges on one corner that I cut off, it looked great to me). I went on Amazon and ordered the good contact cement that's made from the original nasty chemicals. ($14 shipped on Amazon)

I decided to go with 54" wide so the platform is about the width of my transom tie down loops. At the tip, I went with 44". I came straight out 14" and then angled inward. the platform is 24" deep, so there's a right triangle cut out that's 5 and 10" on the respective sides.

This was pretty easy to cut using my chop saw. Another harbor freight purchase put to good use.

I had a pair of 12" stainless steel grab handles that I'd intended on using for my Supra but never got around to it. I decided to put these to use on the new platform. Something to grab onto when you're in the water after a run is kinda nice.

to mount the handles, I drilled a hole so I could access the nut on the end of the threaded bolt that was part of the handle. I just drilled a hole and enlarged it as necessary with my jig saw. I didn't care too much about the looks of it as it's going to be covered with the padding.

Here is a look at the platform before putting the pad on.

And here is how it looks relative to the OEM platform:
https://lh4.googleusercontent.com/-_kz7WRTkWXI/VDhvPMFrW9I/AAAAAAAAUiE/mPjziJzcVlI/s800/20141010_142437.jpg

I used the platform as the template to cut out the pad. then I did the contact cement per instructions and applied it with a 6" smooth paint roller I had laying around.

I covered all of the platform with the hydroturf and smoothed it on with my wife's rolling pin. (I didn't tell her).
https://lh3.googleusercontent.com/-Jyaqz453dIA/VDhuxypv3zI/AAAAAAAAUhk/HhKz7bySuew/s800/20141010_155343.jpg

I also smoothed out the edges of the HDPE with a file. I figure I can smooth it out some more when it's on the boat if needed. The contact cement says to wait 72 hours before exposing it to direct sunlight or temps outside of 65 degrees. So I have it sitting in the garage and won't put it on the boat just yet. It is supposed to be at full strength in 7 days. We'll see how it goes.

Hopefully you used the good contact cement. You may want to round those corners, looks pointy.. :)

Yessir, I used the exact stuff you suggested.

[parrothd]

I checked mine, still on there..I get compliments about the hydro, people like that its soft.. :o

Looks like I have incentive to round the corners. if I would have went with about a 45 degree cut instead of a 22ish degree, it'd be better. as is, the corner is still dragging in the wave a little bit. No problem, trimming some more off shouldn't be too hard.

And I agree, rounding the corners will make it look better.

The handles probably cut into the wave as well or will when you add more weight..

What is the total width of your platform including the handles? How much "water clearance" do you have? (i.e. could the platform be any wider and still stay out of the water?)

Above are the dimensions that I used for version 1. However, I'm going to be chopping down the corners some more. basically I'll give it a shot with the width of the tip of the board being 34". so I'll go 5" narrower on each side of the tip. It'll make the angle where the corners are cut out about 45 degree. That said, I'm likely going to try to round those corners for aesthetics.

The handles add to the total width. I'd say they're right there, and I wouldn't want to go any wider or I might be dragging. I do have a 1/2" spacer between the platform brackets and the platform itself.

So I feel pretty good about the overall width, just need some more to come off the "corners".

[trayson]

Made some changes to the platform last night. cut a little more away and now have rounded corners. Sorry for the pic, it was in the dark with my phone...

We'll be testing it out after work today.

Thanks, I tried to make the arc of the curve look aesthetically like a continuation of the curve of the handle. Ultimately I had to use a sharpie on a string as my method to draw the arc. Then I cut it freehand with a jigsaw. It could use some finish sanding, but we'll see how it does this afternoon.

[gregski]

Thanks, I tried to make the arc of the curve look aesthetically like a continuation of the curve of the handle.My first impression was that the curve looked "right" and flowed right into the handle. Well done.

Trayson, Love the new platform. If you are going to do another ghetto gate install I would assume that the OEM platform wont rub the wave as the boat wont be as listed ??? so will the oem get some glass work on the bottom side and re-installed?

hard to say. leaving this one on for the foreseeable future is certainly the easiest move, so I'll likely do that. no real reason not to. I do like the handles. after a set, when the boat comes along side me, it's great to just have a handle to reach out and grab the platform.

[jmvotto]

agreed always liked the supra handle ring.

[trayson]

Update on my platform. I noticed this weekend that my platform seems to be bowing down in the center between the two brackets. it's still perfectly functional but it's definitely not level from side to side.

I'm sure that the fact that it's 3/4" is part of the reason. I have to wonder if the heat of the exhaust is also a factor? Obviously, the fact that I only have 2 platform brackets and no center support (my supra had 3 brackets) is allowing it to bend/warp a little.

I wonder if I would have been better off with come kind of bracing between the two brackets, maybe like angle iron (but aluminum)?

Again, it's not hurting anything and you really don't notice it unless you're looking for it. But I figured I'd mention it. I'll try to get some pics soon.

[5:00]

I was thinking aluminum square tubing at the start of the read as well. Unfortunately it would mean lifting your turf but would probably solve the problem.

[parrothd]

Use 1in... ;)

[trayson]

The price jump to 1" was a LOT.

My platform is still quite functional. I just thought I'd give my experience so others could have it to consider...

[afm187]

Trayson, where did you find the 3/4" HDPE at? I lost my platform and thinking of doing the same and can't find a piece for $130.

Why not put the platform on a hinge allowing it to float up only from the standard position? It would then add no resistance during surfing and still support you fine once some weight was upon it. Or a spring holding it down a little when you come to a stop.

Since the boats are driven so loaded, why not raise the platforms height? Of have multiple heights (drilled or slotted track on transom)?

[5:00]

I have seen more than once where a person hits the transom with a board while riding the board. Possible for the board to go under the platform if it is raised too high or even worse a person. If you have a loose platform they really bang up and down a lot when stopping or waves hitting. Something like this would have the same problem but probably worse. It can get pretty rough out there.
Sorry to be a buzz kill. Interesting idea though.

I have no issues with my standard platform except and occasional spray, wave is fine. I have 4k in ballast easy.

[Fastest1]

Not hurting my feelings. I am very new to this. It was just a thought. I can see your concern in regards to colliding with it either flopping up and hitting it. Not likely to be able to hit the prop.

Next I will be trying to fill my ballast bags with water exhausted thru the engine! Rev it a bit and instant fill. Maybe in a colder climate, Texas is hot enough ;-)

Having a smooth bottom to the platform is key. Eliminating the lip on the fiberglass platforms that acts like a shovel destroying your wave and taking away a ton of the energy from it. Likewise, simply cutting off the corners so that the platform matches the natural contour of the water flow of the water coming off the corners of the hull. That's the ticket.

There's a big difference between this:

Notice above that the new platform only comes out to the tiedown eyes. pretty decent decrease in width.

Nice smooth bottom, no lip.

Awesome thank you for the info Trayson. I'm measuring this weekend and ordering next week.

[xBabyJesus]

Did you guys have any issues with the stainless bracket screws into the HDPE? I upsized some of them as the stock ones just stripped out the hdpe (even on super low torque). In retrospect, wish I would have used self-tapping. But the oversized ones seem to be holding ok, it would just really suck to lose the platform.

[5:00]

Are you threading the HDPE? That won't work. Use castle nuts or carriage bolts from the top.

[parrothd]

I used the existing self tapping screws from the original platform. Just drilled a small pilot hole for each, probably want to use the 1in hdpe as the screws are 1in..;)

[xBabyJesus]

Just regular stainless screws. My factory bracket screws were not self-tapping and I didn't give it a lot of thought before mounting. The ones that stripped out, I just upsized to a larger diameter screw (effectively, now I have pilot holes) and it's holding pretty good. I thought about drilling through and doing carriage bolts, but not sure how that will work once I put traction on. How the hell do you hold them / take it off later? Maybe just regular bolts and an oversized countersunk hole so I can get a socket in...

I am using 1" HDPE, it was like $170 from ebay.

[wolfeman131]

Through bolts

https://www.jacknob.com/cgi-bin/falcon?fcmd=showpart&partid=3592

[trayson]

Yes, I used regular stainless screws. they were thicker than my 3/4" HDPE, so I put a 3/4" HDPE spacer under the main part of my platform. I've had to tighten a few screws, but so far so good.

Hey guys! New to this forum and first time posting. Thanks a bunch for all of your great information!! As a new Moomba owner your information and sharing has been invaluable!!!!

I just got off the phone with SC, the new 2016 Moomba Surf Wave platform will fit the older Moomba's. Same brackets and hardware. They actually quoted me dealer cost which was $396.59 for the platform (Part#812701) and $161.60 for the non-skid (Part#123022). They recommended using the brackets off the old platform to save a few bucks. My local service guy is giving me a quote. He is not a dealer, and I'm sure he'd love to sell you one!! He's getting back to me with a fair mark up. I'll ask him if he's OK with me passing out his contact information on the forum if any of you are interested. He's a really fair dude and has always beat the dealers on price for me over the years. Would be a good contact to have!! Let me know....23036

[psycho-heico]

Maybe see what a "fair" price he is offering, if we get a group buy on platform....

$456.08 for the platform and $185.84 for the pad + shipping.

[jmvotto]

According to Vince, he will only sell to people in the Spokane washington territory area, respecting the dealer territory network.

[5:00]

I got my HDPE for my platform. I went all crazy and got the 1" and Hydro Turf to cover it up.
I don't like the idea of using carriage bolts because they can spin. Of course just using a jamb nut to loosen them when the time comes solves that problem.
I was thinking of using a blind nut like a T nut or a rivet nut. Not sure if that is a good way to go either. They are really clean looking but if they spin I am pretty screwed.
Let me know which is best.

[parrothd]

Carriage bolts for? Just use the screws from the platform..

[parrothd]

Ahh.. If you go with the 3/4 the self tapping stainless screws from the platform may be too long? That's why I went with the 1in stuff, not to mention it doesn't flex. Pre drill the holes, makes the install easier, then install the hydro in case you mess up and drill thru.. ;)

[5:00]

Wow so you just did SS screws from the bottom? I wouldn't think on those 1/4" diameter screws there would be enough bite to keep the platform from snapping off. There are 12 total though. That would be pretty clean.
Right now the stock platform is held on by carriage bolts. Not sure if that is stock? The bolts are WAAAY too long for job on the stock platform.

[parrothd]

So the stock xlv uses carriage bolts to attach to the platform to brackets?

My platform takes a lot of abuse and use and I have no issues with the screws. All three of my moombas are/were setup this way from the factory..

Think they're 1/8 or 1/4? x 1in stainless, self tapping.

[5:00]

Seemed to be stock. They were under the old hardened pad, that I since replaced, on the platform. The bolts were at least 2" past the brackets hanging down and fastened with nylon and SS nuts. I used jam nuts to get a few of them off with no problems. The carriage bolts make some nice bumps under the pads which I am ready to not have any more.
Did you screws tap into fiber glass? The HDPE is pretty soft compared to glass.

[parrothd]

The hdpe is stronger, the platform is foam filled covered with fiberglass/gel coat.

[5:00]

Makes sense. The carriage bolts look like crap and I hit my head on one once when swimming under to check something.

[parrothd]

Yep.. Makes you wonder about moomba quality control, or lack of. You easily hurt yourself..

[trayson]

My oem xlv platform had ss screws. No carriage bolts. Used ss screws just like above, though with 3/4" I put a hope spacer between the bracket and the platform.

Ss screws have been holding just fine.

[5:00]

I will be replacing the carriage bolts of death with the screws for sure. I made measurements from a CRAZ swim platform on Saturday so that's what I will end up with. Good by dragging platform.

Okay, I meant expensive in general. Expensive relative to building your own. But yeah, certainly a deal relative to the price of an OEM surf platform at retail.

I found that last comment odd. yeah, they need to respect their dealer network on new boats, but I've never seen any real need to do that on parts. That said, I have no dog in this fight, so it matters not to me.

[jmvotto]

Yeah I thought it was odd too, it was also a year old , yeas pricey compare to a diy platform ,

[gravity]

My diy platform was close to $400. But everyone that sees it thinks it factory and don't believe I Built it. Most factory ones are $1200 and above.

Yeah, I now remember that thread from WW. Yeah, the smooth bottom is legit. And it came out nice. If the size meets your needs, then that's awesome. I'd still go smaller on the edges, but for my surfing on my boat that'd be a factor. if yours isn't giving you anything that prompts you to tweak it, then surf on!

[MJHSupra]

Amazing work, it looks flawless!

+1 on that.

I bought mine from a local dealer to match the color on the boat. It was over $1k: platform, pad, rub-rail and caps.

I got lucky to sell my old one to net some $$ back. I think I got 300-400 for the old one.
