Surfriding Kevins Area 51 super surf hull TWEEKER X-TREME build ....... maybe

[sportfish258]

Things completed this weekend .

Sanded prepped the entire boat on Sat top and bottom deck ( inside only for reinforcement. ) .

Cut rocker in the rear . Went conservative 1/2 inch since I added so much to the front .

foamed handle pole area

started cutting patterns .


Question : how much reinforcement would you do. The hull weighs 78 pounds with all hardware , inserts etc. The WFC hull is light weight I have to do something . The bottom deck has been cut on a little can't skimp there either . I still think I can bring this hull in under 90 pounds .


Pic 1. 12 oz biax on both sides of the and tray and gunwales , handle pole area ,hood seal. It's made of chop only have to do something

Pic 2 . using up some scrap . Gets biax all the way around . I will lay it all one time so the the corners that are faired out will have a good bond. Also pic is the final hull profile with the rear cut down.

Nice work, glad to see this hull getting some attention (I think it spent over a year in my garage untouched... then to anonter member, etc...) Never guessed it would get hacked up like that though - WOW!!! BIG PROJECT!!! Awesome job on the rocker. Subscribing!

Neil, Didn't I bring this hull to Texas in 06? I am having a vague recollection of this. Is this the same?

 

[sportfish258]

Hey Do Dad , this should clear it up . I think you are step 5 . It's in amazing shape for the age, literally all road miles ........

 

[Big Kahuna]

WOW, that is wild, It just hit me that I had transported this hull to the Texas Freeride, or, I think I did!!!!!!!! I know I had it at one point!!!!!!!!!!!!

Any plans to shorten the bottom deck?

 

[sportfish258]

Josh , Bottom is minus 1.5 cut on a slight slant . I'm still able to use the stock ride plate mounts . I think I'll stop there since the planing surface has been shortened by the rocker. The top came out -4 / 5 ish . I am thinking about moving the top deck forward about 1.5 inches mainly for aesthetics , but I suppose it could move the CG depending on foot hold placement. Glassing this week we will see.

 

[Aircraftsalz]

Looks good... 1.5 will be perfect in the surf! Way to get it done, nice work

 

[sportfish258]

little more tonight. Glassed the front . 3 layers 12 oz bias at the seams (where i cut ) .Will rough in the rear tomorrow then start fine tuning ... sanding ... sanding and more sanding...

 

[WAB]

Loving this project!
Too cool. Keep the pics and confusing humor coming

 

[superwetbrett]

great work dude

Move it forward and put holds all the way to raer. Just my vote. Are you still going to rocker the rear slightly?

 

[sjetrider]

thats pretty extreme...probably gonna push allot of water...ive noticed in the aftermarket hulls ive ridden with more rocker than a sj that they dont "glide" off throttle like a sj does...it feels like u hit the brakes when u let off the gas...there is a reason they stopped putting flip tips on surfboards in 1996...dosnt make u pearl any less just makes u go slower..just remember superjets dont pearl the people riding them do..

i think the am hulls with more rocker and wider bottoms are easier for people that dont know what they are doing in the surf to ride waves but when it comes down to high performance waveriding i think the width hurts you..they are kind of like a crutch for people that havent learned the basics

..u need your ski to be able to rail turns hooked up and slide when u need it to depending on what the wave is doing...when you are turning on the wave before it breaks u want to keep the pump hooked up..the only time u release the tail is when the wave is super steep and u have the lip to redirect your momentum back into the wave...when the wave is flat/fat and u slide the majority of the time u end up sliding off the back of the wave...its all about doing the right turn on the right part of the wave...

id leave the tail alone...i know surfboards are different but the same principles apply...when they make a surfboard with lots of tail rocker u have to add a deeper concave to make up for it...so the rails will have more rocker than the middle of the board...u cant really do that with a ski...adding rocker also reduces the rail line which would make your ski feel shorter but its not going to give u any advantage if backflipping easier is your goal...adding rocker to the rails is just gonna make it not hook up as good if u want to turn with any speed.. i rode a lightweight de with the rails in the back "scalloped" and it rode like crap...releasing the tail is done by weight distribution and proper throttle control..if u want it to still rail turns id leave the back alone..

with that said u did a good job and its cool u are experimenting..that dosnt look easy

If this were the case then why isnt everyone riding 93 model 550's and Fx1's ?????????? Better performace from your equipment does not mean your a rider with less skill.
Just because TC rides a Rickter doesnt take from his mad surf skilz does it? Dont hate cuz you cannot afford it, just post pics of you having just as much fun on your SJ as we do on our AM hulls with big motors, that usually is enough to make me second guess myself. Only to realize that I dont live near surf or I would ride a beater too most of the time. Most AM hulls are produced with Flatwater in mind and wider with ROCKER is MUCHO BETTER for that aspect IMO.

I agree that SJ's do not pearl ( the rider does) however even the best catch themselves struggling to keep from pearling at times, why not improve the hull where you can????????? Change is good, trial and error is good and This build is an awesome example of how this sport has changed and why it changed. TEM came into this sport from surfing and happened to have mad composite skilz and he has made a great change to the sport just by applying his thoughts to actions.

Ride a 550 and be happy if you are all about improving your skilz and not the equipment.

 

[wydopen]

im not against improving equipment but i feel that making a ski so wide that it dosnt turn at speed or has so much rocker that when u let off the gas it comes to a stop is not an improvement...whatever gain u get by it being short and stable u sacrafice wayy to much in the rest of the handling.....those skis are easier to ride in my mind and thats not what i need or want....i dont not like them because i cant afford it...i simply dont think they ride as good for the type of riding i do, which more closely resembles what the average rider does...crank turns...if you are a die hard flatwater freestyle specialist then by all means a short wide ski is gonna help...but now every rec rider thinks they need an aftermarket hull to have fun which is bs imo...

also i wouldnt exactly call my ski a beater..if i put my parts in some fancy hull it would be worth like 20gs lol

Brian , I cut the top deck a few days ago to move to move it forward 1.5 . Also added 1/2 inch of rocker to the rear . I went a little conservative in this area however 1/2 inch is noticeable . Really interested to see how this hull rides with an extra wear thus a setting the back pump 2.5 inch.


Wydopen , You are correct to a point sir, The biggest question you find your self asking while making changes to a proven design is ....... am I really smarter than 100 Japanese engineers with a full grasp of fluid dynamics. The answer is ...... after a few beers Maybe . I'm for sure a better lover but I digress.

The width is the same plus tubbies . The front rocker is started about an inch from the front motor mounts. The bottom is raised approx. 1.5 inches at the fuel tank (I have about an 1/8 of an inch clearance between the top deck and tank. I think this more gradual slope should keep the front from plowing . At least that was the idea . Seeing that I could slide the top deck forward 1.5 inches , I noticed I could pick up about an 1.5 extra clearance . I could have made the step even more gradual . live and learn

Hey Do Dad , this should clear it up . I think you are step 5 . It's in amazing shape for the age, literally all road miles ........

You should finish the clealy drawn, directionally correct sharpie route map... how did it get to you from NC? :laugh2:

WOW, that is wild, It just hit me that I had transported this hull to the Texas Freeride, or, I think I did!!!!!!!! I know I had it at one point!!!!!!!!!!!!

For the record, Harrison you transported the top deck only. The hull (bottom) was always in Colorado until it's trip to NC. :silly:

Project is coming along nicely! kudos to you Kevin!!!!

 

[batesman]

Kev...I don't get it. I mean sure this is neat and all, but rather than spend your time on this, we could be working on my rolling toilet idea. THAT idea will make us a mint!

Seriously though, very impressive. I'll swing over and check it out. I also want to talk you in to making a new hood for my Kawi....and don't tell me you can't either because

YOU CAN DO IT!

Well it's late , and I'm getting closer . I'm playing the ol epoxy set sticky mash it down with your fingers to make sure it stays game this evening.

Very Productive night ... Glassed the rear , foamed and enforced the handle pole area , spanked my monkey , foamed and shaped the final nose / transition to the bond line.


Next on the list .

1. Add two layers of 8 oz to the front half of the hull (outside) .

2. Touch up and sand the rear strakes

3. Form the bond line flange (stay tuned for this one ) . I dun thunked and thunked on it . This will be easy and creative I promise . Probably will not do the flange area until next week so stay tuned and see what the biax master ( I gave my self a promotion) has planned .... Ol Chum .



Pic 1 Using all available scrap ( black sharpie really looks like hell) three layers 12 oz in the seams . (she's getting a little heavy ) still think I'll bring it in around 85 to 90 . Just could not justify carbon on an experiment .


Pic 2 Shows the final rocker you can see it is more gradual and a little more involved than some other rocker mods. It's ok ..... you can say it ....... sure you can .... really .... go ahead ..... it's alright.

STAY Focussed man! LOL Lookin good!

Black sharpie reduces the weight by 10%
