Re: Woo3 and Xensr compared

I've suggested a likely cause of error before. No degrees here, no top 20 android apps, no genius friends to advise on other's errors. However, the woo chips have to work out an average water height level reference if they are going to record a jump height from lake/river/sea level. If the average w...

Re: Why do I need a much bigger board AND bigger kite for a heavier rider?

You also have more drag on a heavier board and displace more water with more weight.
However, the biggest jumpers usually go way overpowered. They are usually skinny with a good muscle to bone ratio and little fat.

Re: Board design -- also a boring question

How is the edge shorter when you're carving? Why does more rocker carve faster? Wouldn't the whole board just flatten out as it loads up? How is the edge shorter when you're carving?- Because square tips are in the water far away from your feet, you need more torque to change the board angle. And o...

Re: Eleveight RS 14m 2018 review

I had a look at an eleveight bar early this year. I like the way the quick release clicks back, no fiddly resetting. Simple reliable looking bar.

Re: Board design -- also a boring question

Why do outlines have to be curved? They don't. Curving off the corners reduces the end width while leaving length. This makes them ride softer and give some stability against nose diving while being more responsive to rear foot control. Also, when you are carving the edge is shorter so the board be...

Re: Affordable Kite - Highest Jump - Longest Hangtime

The switch element v6 are quite floaty and jump pretty well. Good price too.

Re: Do you need to rinse kites?

I think salt water when dried out acts like salting meat, to preserve against bacterial or other organic life degrading the kite. On the other hand... every salt crystal that crystallises between the fibres introduces a weakness under tension. Fresh water is probably better for kites but even the ac...

Re: My first kitesurf board! Eps Foam okay ?

I'm waiting on about NZ $450 worth of 10mm thick M-foam and glass fibre from Gurit. I reckon it's enough to build 6 higher wind robust kiteboards. The foam is expensive until you buy it in bulk, then it's not so much. I wouldn't use EPS though, wrong characteristics and absorbs water too easily. I l...

Re: Mono hulls in America's Cup - this should be interesting

As a Kiwi I'm happy. We have a history of "punching above our weight" as a country and given that the Yanks buy our technology off us to compete with us it's nice that we get a break from them setting the rules again. As for speed... sure, a monohull will have more air and water drag but I love that...

Re: Yet another diy hydrofoil. The plummet hammerhead

Now you've done the progression plummet, and gone to double footstraps, what's your feeling on whether it would have been worth starting with two, or as you did with just the open front one?
