Re: New Wetsuit Skunk stink....

I actually have the same experience with my Mystic wetsuit. It stank the first time after use, I don't pee in it and rinse with fresh water, then dry first inside/out. I talked about it with my roommate, and he had the same with his Mystic wetsuit. All my other wetsuits are Xcel, no problems there. ...

Re: Height or weight more important for board size

I would think that your height should be important, since it determines the lever arm length between your hook and edge. If you are 10% longer (e.g. 2m instead of 1.8m), your lever arm is 10% longer. This increase is slightly diminished since the force you apply is distributed over the lower half o...

Re: CrazyFly Raptor 2020 what size?

My 2018 Raptor in 132x41 is perfect for me at 60 kg. I guess you would like the 135x41.

Re: Stringer in small foilbord?

kiterpep, Don't get too wrapped up in all these complex descriptions. For a 130 cm foam core board there are some simple principles. Aways use same laminate top and bottom. Symmetrical. With high foam density around 60-80 kg / m3 you can get away with thinner laminates. With thicker blank , over 35...

Re: Stringer in small foilbord?

What about a longer foilboard, e.g. 130 cm? Can you still get away without a stringer if the lamination is strong enough?

Re: wing foils shapes

To explain your results to you a bit, in the darker-coloured parts of your simulation (blue/green etcetera), the flow around the airfoil has separated from its surface. In this region, we call the flow stalled, and it will essentially be standing still i.e. at a very low velocity. This creates a hug...

Re: Wing profile info for backyard hydrofoil builders

You could probably extend this method to 3D using tools like AVL or XFLR5, right? At least to optimize an initial design. Modelling in a CFD like simFlow mentioned before could then be used for the refinements. Probably would make for a very nice project. This winter I'm going to build a foilboard, ...

Re: Can go upwind easily; hard going perpendicular to it

I really enjoyed this video that explains more about this: https://www.youtube.com/watch?v=pA4DXSqJa-M Really put into words how I experienced my edge control impacting the kite's position (which also works the other way around, by the way). Should be helpful to you. I agree that you might be riding...

Re: Can go upwind easily; hard going perpendicular to it

Why do you want to ride crosswind on your edge? What you're describing is just how it works. For going upwind, you dig in your edge. The more you go downwind, the flatter you ride the board. Obviously depends on the conditions and your setup how much edge you exactly ride. Are you having trouble to ...
