Foiling Surfski
« on: October 09, 2017, 08:00:31 AM »
Glad to see that someone has started on this.  https://www.facebook.com/revokayaks/.  Probably will find that a greatly reduced boat is possible but we will see.

Yep. Like one of those stubby little white water kayaks.

I asked a few of the waveski makers if they would build me one with a foil mount.  They are happy to do it.  I was kind of hoping some one would pick up the project and do a little testing first :).  My guess is you could get away with a greatly reduced boat.  Likely smaller even than a performance waveski but that would take some fiddling to figure out.

Haha now that's a wierd coincidence , I live in Jbay :-)

But yea , IMO that's the perfect platform to start developing either a DW or surf kayak for foiling

Yep, a full length ski would be a nightmare as trimming through body lean is essential when we surf ski but foil/balance trimming when sat down is going to be challenging. Would fore/aft foils be better in this case ?

The thought of swinging that huge eggshell nose and tail around in good bumps and having it catch and bash while under pressure...I don't see that working on a lot of levels.  If you used two foils in a flyak configuration they would need to be pretty close together to avoid losing one behind the swell in many instances.

There is footage online of a dual foiled K1 (I think it was) on flatwater and that worked really well but required a lot of energy to get it up. It also wouldn't work well in the swell. I think your suggestion of a short length wave ski is far better.

I know nothing about any of this but 1st thing i thought when i saw it was how do you trim front to back while sitting?

There is probably something to this 'Idea' but the end state is going to look nothing like this.

Using Kai Lenny as an example.  He broke the whole low speed foiling wide open with his cut off downwind board. 

He would never again use that board.  He is foiling on short SUP's and dinner plates.

The long, extended platform with foil attached was just a step in the evolutionary process.  Once your up on the foil you want the entire craft to go away.

Beasho, re: Kai, yeah what about that 3'9"!!?

Admin you may have to be the crash test dummy on this one. ;)

But as far as trim, if the balance is right you could do a to. Of trim just by moving your upper body. Refer to the OC-1 guys to see that in action.

So weird that every water sport is looking into adding a foil. Really fun time to be in paddle sports.

I'm going to trademark the word unifoil.....mount a purple metal flake 60's stingray bike seat on top of a foil...... ;)

Stoneaxe, I love it.

Seriously, have you seen the 3'9" board (disc?) that Kai is surfing? Nuts.

How you gonna adjust pitch control in a ski?  Sitting on your butt seems an odd way to have to deal with pitch.  Of course you do adjust back and forth with traditional ski riding by leaning slightly forward of the CG (I've only got 10 months under my belt so I'm no expert) but from what I've seen of the stand up foilers, they're really getting it on with the pump and the pump is what keeps them up.

I'm just not seeing it.  Will someone do it please and post the video?

Yikes! I have a 9' international class decked surf kayak that I am not using much. Maybe once a year. Well built carbon Kevlar boat by "Murky Waters". Any kayakers out there? Do you think it would be possible to roll a kayak that has a foil attached? Definitely don't want to be a swimmer with a boat full of water and a foil attached.
