Que?

Is that first one particle board?

 

Looks like a competition starting here. I see you used a square tail in your design. Why not a pin tail? How does it smoke?

 

Sometimes I go too far.Good job bro. Hope they serve you well.

 

Looks like fun for summer. I can't imagine that particle board will last, but I guess it doesn't really matter. Do you plan on standing up on the long one?

 

wheres the foam??

 

Good stuff patgeds, Faster than Satan!

 

I like 'em...they all seem like they'd be fun with a pair of fins...I would have blended the concave a bit or just extended it through the nose...bottom contours are for control...however, I'd give it a whirl.

 

How thick are the shorter ply ones?

 

With a 3/8" thick rail and parallel outline, I don't think you will need any more "control," they'll have all the hold you need.

 

I think live4truth was telling you that because these are finless, you could use concaves to keep them from sliding out (I assume that's what "control" means). I'm saying that a rail that thin (3/8") gives plenty of hold on its own, especially when combined with the straight outline. I really like the simplicity of these designs. Cut to width, trace a garbage can lid for a nose, and call it done!

That is essentially where I was going...now multiple factors are at play in this situation...but essentially, I still fall on the argument side that concaves are going to help with water flow direction and in turn on aspect to help "control" the board movement/direction (lot going on in that sentence).

Swaylocks has 9 pages on the issue...I think kcasey's argument on pg., 7 is helpful (LINK).
