New Carbon Hull........Bottom modification help needed???

[Kawastyler]

Hallo Freestyler,
i have build 4 carbonhulls with 8mm honeycomp and weigth from 18kg up to 28kg. My hull is at 18kg......jet goes great with oem 700ccm with FPB-pipe and MSD.

But one big problem is: the ski is so light that i not can ride me a wave for nosestep ore roll.....

What can i do,i work on a new hull mold with Yamaha Bottom and SXRtopdeck

Is a smaller bottom better ore extreme shorter???
Have somebody of you pics and informations from Rickter,Q8?????

Hope you understand my problem and can help me......

Thanks,Andy

IMHO, the ski is simply too light for a setup wake.
Trim it up, maybe?

I think you will have to change to the the new Lenzi style hull at the rear to get it to sink in

Do you have any pictures of the bottom of that hull and what's different from stock other than it being lighter?

Hi...
I live in France and i work with Lenzi for Yvan Potanin...
we haves tested all the hull ( Q8, rickter..)and all the motor (waterdawg, x-screm.etc)
too light is not good..minimum weight for the hull is 34kgs...with hood
In 2006, lenzi used a carbon hull at havasu, too light, it had been to make to weigh it down during the week end with a disc of bodybulding..

 

[patatak 111]

actually, the good shape is sxr bottom hull, (Q8 and new Lenzi boat)..
very large for a big motor...(Polaris EME and Polaris PSI for Potanin boat)
very stable...
Q8 and Lenzi boat are made for a "top gun " freestylers but not very good for freeride...
Rickter is a polyvalent hull..good for freeride and easy for freestyle!

[patatak 111]

this is a Lenzi hull prototype...Old of January month..
The hull is very short..(cut behind and on the front)
Fiberglass model...38kg with hood..
The top deck is belitled of 5 cms..
Now, this is a jet of ERic Forney..France..top Free rider..
800 sxr engine with factory pipe and stock pump..

Have you tried different rideplates, a longer plate will help trim the hull down in the nose. Or shim a shorter plate down to get the same effect. I would say try a longer or even extended rideplate in the surf before you add weight. Ski looks nice.

Now..this a last prototype of lenzi for Yvan Potanin..
Fiberglass hull..37Kgs
The hood is more "flat"
the pole is more on the front..
this hull is more shorty than the January prototype..
1100 PSI engine POlaris and 1100 EME engine...145 kawa magnum pump...
Power factor..Total loss and 48 novi..
6 boats for Yvan...
This boat is very dificult to ride for novice...To shorty, and big power!
it's a spécial boat, for a "topgun" riders!

 

[patatak 111]

Yes..For freeride, Eric Forney use a stock SXR ride plate on this boat...more stable...
but Yvan use a very very short ride plate, maybe..20 cms length.
This jet is "explosif"..
He do back flip "clicker" on the flat!! and back flip superman!

 

[patatak 111]

Lenzi make a hull in 4 days in Brazil for Yvan...He haves a lot of employed working in her factory boat..http://www.thorus305.com/index.html

it's easy for him to made a new hull according to what Yvan want..
