Outline and tip shape

[plummet]

Well my waterline drawing was a 2 min mock up so guys could start considering waterline in their designs.

Checked out my board in the water today. Waterline is just forward of centre during upwind tack.

Waterlines at different speeds, edging, flat..

Of course. But the important waterline is that of the upwind tack.

agree. But I think it's going to be some kind of diagonal across the board, probably within 15 degrees either side of your line, and mostly somewhere between the centre and the front foot.

which is kinda all the lines that downunder drew

btw, that board of yours has a really nice shape. The more I look at it the more I like it.

I think I'm gonna commission Kerry to make me a mini mako.

Cheers man. It is a glorious board in the waves. But a little power hungry. I wanted to take on big lumpy faces with out nose dive. So I dialled in 55-60mm of constant rocker with a front tip kick of 70mm. I didn't put enough concave to offset the rocker. It makes it a machine taking on those big swell days 25+ knots. But sub 20 small swell days its too rockered or not enough concave to offset the rocker.

The next board will have the same rocker on the rails but i'll pull up the concave for a flatish water line.

The issue i do have with the high concave mako is that the rail to rail transition is not seamless, once its locked into each rail the carve is magic. But the transition is more like a pop than a seamless transition. I put this down to too much concave. So I need to find the magic rocker that gets me as flatish water line as possible but doesn't impact the rail to rail transition too much.

PS I find the quad fins the best configuration.

Super cool clear board. Who makes it?

I'm going to smooth out the corners as suggested and probably keep a little pinch in the waist.

What are 1 or 2 key things to do to reduce spray?

Thanks dude I made it.

@lovethepirk: My opinion is the size of the board has the biggest impact. Bigger boards spray less because the waterline is more rearward and the front tip rides higher and is less likely to splash through a crest.

To reduce spray the trick sometimes is to round the rail edges. How much round or sand is a magic.

PS

Nice pics rynhardt.
