X2 hull sponsons

[crab]

What do you think about me developing a set of X2 specific sponsons that are a bit more aggressive than currently availiable designs? I'm thinking about working on that this winter now that I have a spare hull to cut patterns off of and experiment with.

[brett]

what do you mean by more aggressive? wider?

[crab]

Probably wider, perhaps longer, and follow the hull outline better, by no means a copy. One problem with the X2 is the narrow front, and wide rear, looking to make a sick wave shreader. If you look closely at this picture, you can see how the front handles the water.

[brett]

is that the infamous luke suva? i see what ya mean. have you tried regular ones yet?

[Matt_E]

That is one sexy Suva there.

[crab]

is that the infamous luke suva? i see what ya mean. have you tried regular ones yet?
Yes, and I am not his .....o nevermind. I personally have not tried the regular ones, but know they were not really made for this hull, thus room for improvement. My hull reshape from last winter made so much of an improvement in overall ride, I think I may be on the right track. I have had not one complaint about handling, and may take the next step. Pete took the X2 to the next level, I'm just trying to improve on his ideas. Did I mention parts that have the hull curve built into it so there is no bending?

[djyox]

Well if you make your own, maybe its not a bad idea to make some type of deal built into the front sponson that would make it a simple bolt/glue/rivit up job. Like a built in extender tube or something??? I dunno, just plant the seed in your head and let it grow....

[shawn_NJ]

Crab if you make it....they will buy! Put me down for a set! I love my tubbies but a more radical design would be awesome! Especially something DESIGNED FOR x2s!

EDIT: And of you do a mold of your bottom mod I will buy that too....lol

[Vumad]

sounds cool. I liked your build. It's cool your trying to find better mods.

[madscientist]

i am thinking of making them as well possibly with the exhaust running out the trailing edge of the , well exhaust side

EDIT: And of you do a mold of your bottom mod I will buy that too....lolIf I really get serious about this whole thing, I will pull a mold of the front reshape. I really need to pull the motor out and flip it over to do this easily however.
CPRman and I are talking about pulling footholds and a few other things as well, it really depends on my time this winter, I have the heated shop. If I get a working sponson prototype I am happy with, I will send a pair to somone for the east coast sea trials.

[Snackem]

Crab have you taken your 2 X2s out to the flatwater for some side by side handling tests? I'd love to see how a stock X2 hull handles compared to your moded boat.

I did not see a spot for front exhaust so is your exhaust going to come out of the side of the sponson or are you running rear exhaust?

[crab]

On my ski I will just take the finished sponson and trim the front to fit around it probably, I really don't want to :-):-):-):-) with the thru hull now that its done.

[WFO Speedracer]

My hull was damaged considerably on the left side and left bottom,the side has been repaired except for the very front part,I will probably be doing a mod similar to Crabs on the bottom of the x2 this winter,it would be easier than trying to put the stock hull lines back in I think .I may change it up some but it will be similar for sure,thanks Crab for showing us the way.

[madscientist]

crab,

where did you find that foam?

[crab]

Just showed up 5 minutes ago. I will get some pics on the ski after lunch.

[RAGS]

hell yeah man cant wait to see them on the hull. i ordered mine this morning!!!




<--hope you don't mind i stole your pic for my new avatar

[WFO Speedracer]

The stuff I used is called PVC foam.it came from Farco Plastics,The neat thing is that the whole sheet is about $85.00 .It is thermoformable with a heat gun or for smaller pieces putting it in an oven at 150 degrees for a very short period.That is how I formed the curve to the hull,you heat it and form it on the hull while it cures,takes about a minute or two.The pic below is what the sponson looked like before it was installed and glassed on,as you can see it was two seperate pieces that were cut out ,thermoformed and glued and screwed to the hull then glassed over and faired with west system filler.The first one was reshaped fter I installed it,on the second one I did most of the shaping before I installed it.

[crab]

Pre curved, fit is good.:thewave::thewave::thewave::thewave:

[madscientist]

those look good. thAnks for the heads up and will have to get some myself

[ADDict]

Good business! Can't wait to try those out!

Make it two for EAST COAST

and Crab you can save us couple bucks on shipping by sanding two sets to one person we live not to far apart

Am I missing something here? why do you guys want a mold of the hull bottom?

:Banane09:Actually Victor, I'm not certain that a plug is really the right way to go about it. It would be hard to foam in behind it solid, and you would still need to glass it in.

Ummmmmm Crab I know that much,mine looks almost just like it now,thanks for the ideas.Now if you were takling about splashing a mold off yours then producing a piece from that mold,that I would understand,Is that what they are asking for?

[crab]

Yuppers.

[vitalikol]

I was talking about sponsons. I woud like to get a set
and Crab about nose : I will do more/less same like you did in yours build with foam and glass it over

[crab]

[vitalikol]

so you quit your own design ?

[crab]

For now, didn't know Louie had them in the works, and for the price its just hard to beat. He did a nice job on the design, as they are pre curved and almost just lay down. They will need to be foamed on the back. Time is the one commodity we all seem to be short on.

[dqh]

how would someone get ahold of Louie?

I bought a set for my build (http://www.x-h2o.com/showthread.php?t=29480 ) as well. Fit pretty good and the price was unbeatable.

Crab, how far down on the hull are you mounting yours? I did mine almost flush with the outer chine and now wondering if I should have left it up a little. Not sure how this is going to affect the handling (turning).
I'll have pics shortly.

[crab]

I plan to hold them down as well, here is a pic I took of Pete's just before we left on monday. They seem to have more flexibility as to where you can put them since they are made a bit different.

[x2skier]

Yeah, I have mine much lower than that. I just found the best spot which followed the contour of the hull. The end is about 5" past the open footwell.
Oh well, too late now. I laid some epoxy filler on the edges to blend them in.

Hopefully I'll be making an appearance at Daytona next year. Looks like you guys had a frickin blast.

[crab]

Blowsions are a little shorter and he has them even with the pisser in front.

[surfjetlouie]

someone is looking for me? PM me I have more of them....:wave:

[crab]

They seem to have more flexibility as to where you can put them since they are made a bit different.On carefull rethought, I will probably hold them up a bit similar to Petes, they work very well on his.

[crab]

On carefull rethought, I will probably hold them up a bit similar to Petes, they work very well on his.

Right now as it stands, I will be 7 3/4 from the footwell, and 1 inch up in the front from the bottom of the hull.

[WFO Speedracer]

I am very happy with mine but these would probably work even better than the ones I made,what can I say I am a tightwad lol.:lmao:

[crab]

Right now as it stands, I will be 7 3/4 from the footwell, and 1 inch up in the front from the bottom of the hull.I changed a little, dropped down a bit after taking in to account my modded front hull. Pete's are about even with the stock hull in the front if you feel or look at it, mine hull is almost even with the outer chine. So, I raised up a bit in front, but not huge, pics to follow.:smashfreakB:

[crab]

Step by step, foam, fit, epoxy thickened with cabosil, SS screws, remainder of epoxy thickened with fairing mix for putty while wet, tomorrow sand and paint.

[crab]

Last one, you can clearly see the reshaped hull and the added tubbies and why I held them up a bit.

Man !!! You are an inspiration for all of us

very nice crab, im ready to get mine on

[Nefarious]

Hey crab, the new sponsons from surfjetlouie seem to have a bit of a curve in them allowing them to sit flush against the side of the hull. Is that true or are the pics playing tricks with my eyes?

[crab]

[Nefarious]

Yes they are precurved, and very close to the actuall hull shape.


Hmm, i just received mine today and they don't seem to follow the shape of the hull at all. When one end is flush the other sticks out about 1/2".

I wonder if something changed????

Find your spot and secure the front, then drill and screw the back (mockup). They will pull in with ease. Only thing I noticed with mine is the right side was not trimmed exactly to match the left, hit it with a belt sander and wa-la.

I just went and measure; it was ~1" off the hull in front and ~3/8" at the rear. Having not messed with Blowsions product I don't have any frame of reference.

Okay, now I feel better. I am able to press the ends in by myself. I read that you used #8 oval head screws but what length screws did you use? What about the back end where the last screw could come through the foot well?

It did. I used mostly 1 inch, and 2 inch everywhere else. Next time the motor is out I will take the dremmel and grind them off.

[Nefarious]

So you used 1" around the footwell and it came through the other side. How much? I just turf'd the ski and don't want to screw that up or stick the side of my foot with the tip of the screw.

At least 1/4 inch, that reminds me to cut it off.

He is right, real tubbies are a huge PIA to install on an X2.

great ive got 2 sets in the garage im going to fit soon looks like im going to have to gets some beers and get some one to help me do it

[madscientist]

looks great crab

[crab]

Rode with clonies on today, can you say "crazy turn guy". With the short rideplate cut to the first rib and the hole gone, she would turn on a small dime, but had some issues with rollover at moderate to high speeds. Sacrificing great turning for stability is probably an asset when surf riding, but not great for zipping down the glass water in the river. Note; new primer location and hand warmers.

[surfjetlouie]

I used to put one pisser hose inside my wet suite

[madscientist]

looks a little chilly?


rollover? = chine walking side to side?

[crab]

rollover? = chine walking side to side?This was a warm day...lol. No chine walk, just wanted to roll and dump you if you weren't paying attention, turns like a mofo however......:Banane09:

[madscientist]

DO YOU THINK THAT IS JUST A RESULT OF PLACEMENT OR JUST (oops) or just the nature of the new design?

i'm wondering if it's placement myself front to back?
looking at a pic of the hull it maybe that yours are a little far back not allowing the tapered trailing edge to do it's job of directing the flow back to the hull at a more centered location. we've talked about the height issue and are both on the same page there.

Its not the sponsons at all, there is virtually almost none of it in contact at higher speeds. I'm sure its the ride plate being a bit too short, it just screws up the tracking at higher speeds and allows the hull to do wierd things. Really doesn''t matter for surf, as you are always turning and jumping at slower speeds anyway.

[WFO Speedracer]

It is probably the ride plate,I have the extended plate on mine and it is dead stable at wide open speeds,it also turns like a mofo,I haven't tried the stock length plate yet or a d -cut plate.I may just go with a stocker first,I am not sure about the d-cut.Maybe I can borrow one from someone at the freeride and check it out.

I will be trying a few different plates this spring to find the one that works best on glass water, or perhaps make one from glass. The stocker has a few degrees of downforce built into it and the stupid braking hole, my PJS is flat with the hull, I would like that in a glass/carbon version.

[WFO Speedracer]

I am running an old Tucker Rocky racing plate,works well but its pink,that'll have to go

[cattledog]

Its not the tubbies, DEFINETLY the ride plate. Mine tracks great, my brother's (cut an additional 1.5" off the back and rideplate.) is ALL OVER THE PLACE at high speed. I have my motor out now and I'm chopping another 1.5" off the back. Turning and loose handle far outweight high speed stability. Plus I'm advancing my timing so much I wont be able to hold the throttle open wide for more than 10-15secs.

hey crab nice pic, i love your handle bar pad, how cold is water, did you fall into water, what did you use for hand warmers

[madscientist]

pisser is t'ed off to the grips kind of like sled warmers, but water instead of hot air

[crab]

hey crab nice pic, i love your handle bar pad, how cold is water, did you fall into water, what did you use for hand warmers35 degree water, tried to stay out of it. I took one of lines to the pissers and routed it up through a hole drilled right next to the cable hole.

[RAGS]

i rode yesterday, the water temp was 38 and i tried like hell to stay out of it. i only got wet to about my knees and a little spray in the face every now and then. i need to rig up some warmers. i dont know about you crab but it felt great to be back on the water even though it was cold.

Use the 3/8 vinyl tubing all the way to the grips, I had a nice even flow on my gloves the whole ride.

[WFO Speedracer]

I also rode yesterday,the water temp was about the same,I also had every intention of staying out of the water,then I got the bright idea to check my W/O rpms with my handheld tach,count that mistake #1,to do this I rode the ski with the hood off,mistake #2 and yes I did know better,I did have enough sense to put the tach in a plastic bag and put a zip tie aroud the antenna.About 30 seconds later the laynard came off and since I had the tach in that hand I didn't have it attached to my wrist,mistake #3,laynard was lost and before I could get the ski restarted it nosedived gulped a huge amount of water and sank,mistake #4.Now its bobbing up and down like a cork and I am trying to swim it back to shore using my tach as a paddle,and that makes mistake #5.So about a minute ot so later a boat comes by and tows me in,so most of yesterday was spent drying out the ski and the tach,both work fine now. :grumble::censored::Thinkingof_:
