Hi everyone,
I'm planing on building a race - foilboard in polystyrene and epoxy to go with the Moses Vo-Race.
At this stage I'd appreciate if someone could advice the overall length + width and the distances between the footstraps from your experiences.
You can refer to the handscetch below if you want...
Good Winds,
Flo

God luck and have fun building!
Overall Length seems to work well at 5'
Width at 21"
The "B" distance you use in your sketch I measure a little bit different. 1.75" off of center is where I've been putting the inboard strap insert. Then ( "E" ) 45º and your next strap insert at 6.5"("A").
Regarding stance. Seems like 24-27" on the insides of peoples feet seem normal.

I think your front strap positions are too wide, you don't need that kind of leverage as far as I can tell.
Most boards seem to have the straps pretty central.
nice idea though

I agree with footstrap comments above.
And you don't need three footstrap positions in the back, you will only use the centre one.

Thank for your feedback guys, expecially SpunMonkey.
SpunMonkey I assume you mean from boardcenter to inner footstrap insert =1.75", correct?
How much nose rocker would you guys reckon?
Good to know that one footstrap on the backfoot will do the job...
Otherwise please don't take my rought hand scetch for granted.
It's meant as an indication for the dimensions only, nor the outline or the front footstrap placement need to be like this.
Good winds from wet and windy Perth,
Flo

Seems to work for me. Cant finish a tack yet, though when I'm hanging from the kite in a duck tack attempt I can have both feet comfortably in the front straps with this separation. Also feels good upwind and reaching.

Good call on the 5 hole strap inserts! That will help a lot with tuning.
