I'm starting to design my next board & need some advice on a moon tail (which I have never done before). This will be another Kite surfboard for light wind days used mostly in mushy waist to chest high beach break. I'm anticipating the board to be 6' x 20-1/4" x 2-5/8". Nose at 14-/2"; tail @ 16-1/2". 5 future fins so I can ride either as a thruster or a quad (Though I'm guessing I will mostly ride as a quad. I like how "loose" they are in the wave).
As I have never done this type of tail before ( though i try something new on all my boards to expand my knowledge) , I thought I would put this out to you all for advice.
Is there any formula/ratio for the design of the width/depth of the "moon" versus just "make what looks right"? My thoughts are to extend the line of the rear side fins of the quads all the way to the tail and make that the "points" of the moon. What do you think? and How deep should I make the arc of the moon?
