Superfreak with tubbies?

[masterblaster]

I noticed that some of the RRP team had put tubbies on their fr2 evo hulls,It seems like they carved and railed better at wavedaze than previous rides at WF. I really like the freak in surf,its a fun ski,but makes me wonder if tubbies with the hydrofoil concept would work on a freak as well,Im sure it would help keep the pump planted better on tight railing turns,but would it over come the extra wide rear rails and let you get that far over to begin with,anyone have tubbies on one yet? Gotta give scott S the credit for trying them on the matrix first,they really seemed to work,he got gomez to try them on the matrix and then the fs2 and it seems to be spreading into the rest the rrp team

I was going to put tubbies on my Freak and strongly think it'd be an improvement. Only reason I didn't is cuz it was a carbon hull and I didn't want to affect resale value since carbon buyers are usually cry babies about weight. MadnessMaker in Long Island has them on his Freak and his wife's Freak and they love them. I'm drawing a blank on his username

I can't think of the guy but he and his wife are super nice. They have let me borrow their beach cart every daytona on Sunday. Two sick freaks in the bed of his elaborate truck setup.

@madness maker ... I believe.

madnessmaker. his has the blowsion destroyer tubbies off 08. idk which are on the other

Awesome that someone has tried it,Mine is carbon and id love to try one before I do it,I was thinking blowsion destroyers also,deff dont wana glass them on. I saw them at tona last yr ,they didnt have them on then. they are like a light blue gray color right. Wonder if he is making the NC ride? I didnt see them at wavedaze this yr. ill see if I can get in touch with him.

ID love to try cutting down the extended part of the bond rail towards the end and and reducing the width of rails towards the end,that really also seemed to make the matrix scott did ride and land alot smoother and rail much deeper. I really dont need the super stability that width provides. Imagine a cross between a jb1 carving and stability of fr2 lightness and anti pearl rocker of the carbon freak.

The skis are white. The tubbies were off my 08 superjet, so I can comment on install of the destroyers. Definately not committed to them if you use the destroyers, blowsion includes some neat stainless inserts that are glued to the interior of the hull. I think for a short ride you'd be OK with not gluing them in. If for whatever reason you dont like it, the holes can be filled with chopped carbon and epoxy.

What is the diff is width of the 08 sj tubbie vs the 97 up ver they have? blowsion lists the need for hul extensions on the sj with the wide version to work well with high speed cornering? Whats your impression of how they help make the hull rail? does the pump stay hooked up on a railing turn.Any pics of where you positioned them...

Sorry maybe misunderstanding, the skis are not mine but I know the owner.

installing tubbies on our freaks was one of the best mods we have done to them, i always wanted a little more as far as ability to carve harder and stay hooked in turns, these made it happen, i always had issues with a fine line of pump unhooking in turns and sliding... i went with the 08 up blowsion destroyers, they are thinner than the std destroyers and bolt on as well. i didnt want to go too big on a sponson and possibly upset handling of an already wider hull. also wanted a quick install.
i installed them 3/4 inch off the bottom of hull so they are out of the water at high speeds as to prevent chine walk.
had to grind the backs slightly to get them to fit against hull somewhat flush. and filled any voids with white marine tex.
given i had time i would give the larger pre 08 sponsons a try. but more then happy with these.

 

[XJCrawler]

I wonder if the rickter specific destroyers would fit better then the superjet destroyers

 

[madness maker]

I was on the edge of trying a set, but didn't wanna be stuck with them if they didn't fit. Tried to find a loaner set for fitment.

Thanks for the info madness maker.Im thinking of trying the pre 08 destroyer tubbies,I really want the full hydrofoil effect so I can hold this thing all the way over on a rail and keep the pump hooked up,the rear of the ski is going to have to sink alot in order to do that. Its carbon and rides really high,Ive filmed it in corners at speed,the entire jet is still completely out of the water. Im not sure on placement,Im looking for fairly fast cornering speeds,freeride surf speeds,nothing bouy carving speed. Its a great hull I enjoy for most purposes,im just trying to get it to do something its really not made to do,I can give up some stability to make it happen..
How much father over can you rail and still keep the pump connected with these installed?

Torr,

When I added the tubbies on my Trinity Matrix, it took away a lot of the fun sliding and made it carve. The tubbies are like an airplane wing (airfoil) upside down, when you lean to the side, as the tubbie gets further into the water, it starts a negative pressure where the tubbie starts curving up in the rear, which causes it to pull down and hold the ski to the water. http://en.wikipedia.org/wiki/Airfoil

The steeper the upward curve at the back of the tubbie, the harder it will stick. If you move them too far forward, they will cause the ski to plow. I originally mounted mine flush with the front of the hull rocker, I ended up moving them back 5" toward the rear. Now it carves.

I would like to build a set of tubbies that had the rear angle adjustable so I could make the handling looser when I wanted it. Some days I like to carve, some days I like to slide! It seems you never get the best of both worlds

Ever held a set of destroyers? You could glass on a set of glass sponsons, put a few bricks in the engine compartment and still have added less weight than the destroyers.

I think Tom21 changed his sponsons to 3-bolt style. Maybe you can find a quality 3-bolt, have it made in carbon, and silicone it to the hull.

Scott,nice explanation,Im pretty sure the freak will have no trouble sliding even with the tubbies on, off throttle and holdin it flat.I had tubbies on my sj and it would rail a hard corner and almost drag handlebar in the water,but if I wanted it to slide and held it flater in corners it would slide ok.I like your idea though,if you made a up and down glass recess in the back to bolts you could loosen and slide them up and down,might be a good tuning point for some who wana get them right for their style and just leave them there.
5 inches back,that prolly made a large diff,can you post some pics of your current location.

I have seen the tom21 sponsons with the 3 bolt,they might be worth giving a shot also,are they much lighter?

 

[ScottS]

Didn't have a good picture, yes it made a huge difference

The destroyers are solid fiberglass. No foam, no voids, at least that I can tell. Anything is lighter than they are.

Tubbies for life FTW. Its not about surface area on the skis. its the hydrofoil effect on the rear end taper of the tubbie that helps keep the center of the ski in the water also seeming to keep the pump engaged. My biggest tiff with the aftermarket scene was coming off of my 04 superjet with destroyers being able to rail top and bottom turns on waves with fluid ease. Hopping on the matrix I progressively gained confidence and ability in a lot of air areas but lost that ability to turn well, which became very uncomfortable. Aftermarket hulls all have their own specific values and improvements over others. I never cared for every one i rode over the other during demos including the Rickters. However adding the tubbie sponsons and riding more skis set up with them has simply proven to me that they provide these hulls with the additional footprint you can not add in a mold to make these skis carve the way i wish for them to. coming to this realization made it so much easier to sign with RRP knowing I could get everything I wanted out of the EVO-1 including its unbeatable quality, strength, finish, and design. If you are not happy with your girlfriend in your garage, give her a second chance. Pony up the $300 buy a pair of bolt on boobies before you kick her to craigslist and wait for another new hull. Buy the blowsion destroyers for ease, if your bondline is rockered with the hull buy the Evo-1 Destroyer tubbies and they will fit best. yes its extra weight but if you care about how your aftermarket hull "corners" all the times your not trying to spin around doing set up wakes, you will not regret them. They are not for everyone and some hulls for freestyle are better off with out them. All i can say is that for my riding style for any hull these are a must.
