Re: Does a knot in the kite line really half its strength?

dull chum is right, my favorite paper is the one done by black diamond & Tom Moyer, Tusting and Harmston here http://user.xmission.com/~tmoyer/testin ... h_Cord.pdf A figure 8 knot (very strong knot) is 90% on nylon but this excellent figure 8 is only 50% breaking strength on dyneema or spectra and ...

Formula to calculate proper kite size

So the wind force goes to the square of the wind but you add riding speed (apparent wind) which is usually somewhere around 15 knots, and if the board width and rider size work in a linear fashion the formula looks something like this: (constant * rider weight in kg) / ( (wind speed in knots + 15 kn...

Re: North Trust Bar 5th Element design flaw

This had never happened to me before but it obviously CAN HAPPEN! This is a problem NKB needs to address and correct in their next Trust Bar - and for that matter, provide a retro-fix to existing Trust Bar owners. Doesn't seem like a flaw, since it can happen with literally every bar with any kind ...

Good job. Not panic-ing is pretty important.

Re: Using Cabrinha Crossbow with 1:1 bar

Is there less bar pressure using the 1:1 bar? Exactly half as much pressure with a 1:1 bar, that's what the 2:1 bar gives you a mechanical lever of 2 to 1. try it out, see if you like it, and be careful about properly tuning the kite, a 2:1 kite doesn't need to be tuned as carefully because the bar...

Re: Kiting and Surfing timing

A typical swell comes from a storm a thousand miles away or more (storms this far away don't last long enough to reach shore). Sometimes, a storm can be faster than the waves, and reach shore first. But while the storm is at shore, the waves are blown up and disorganized. For good surfing the waves ...

Re: HELP! Rear lines have major slack!

When I'm launching my kite, it's either my left or right rear lines that have slack in them. This causes my kite to not fly up properly and takes much effort on my part to bring my kite up. I think this problem with my rear lines also affect the way that I jump. What can I do? My lines are the same...

Re: Self Launching in less than 10 knots

wind on the beach at ground level is only 5 or 6 knots and the kite won't stay up on its edge. We have a wind shadow where we launch, so here's a method you can use: 1 put the kite directly downwind so one wingtip barely catches the wind 2 walk to the bar hook in. walk directly backwards, the kite ...

Re: Leaving lines attached when packing away

4. Walking the lines out, is often felt as a necessity to be sure there are no crossed lines - but when you do this, the bar will usually be spun a couple of times - so makes no sense as not easy or impossible to see if any crossed ones, if they are spun multiple times - as they will be usually if ...
