Surfed around a little trying to find out about the conductivity of kite lines. I found this copied text on a kiteboarding site. Obviously, I have no idea whether it is accurate in whole or part. And, I have seen dozens of sites that of course repeat the traditional teachings of don't hit the lines. -- jim

This happened to me more than once while flying a stack of maxima power-delta's on Kevlar lines. Kevlar from the litlle i know about it has a very high content of cristaline carbon which adds to it's tensile strength but also makes it a great electricity conductor. After the first few times i got zzzz'd i went home plucked my trusty ol' Fluke multitester and measured the resistence of the line . For dry kevlar 200# line i got 900 ohm/meter while salt-water wetted dyneema of the same test-strength was barely conducting anything through a 20 cm length... This means that wetted Kevlar lines of around 30-40 meters will probably have a total resistence of 20Mohm / 2 ( two lines ) . Supposing voltage differences of around 5000 volts between the kite and ground you'll have some .5 amper trying to flow through you towards theground..OOOPS You can either touch the handles to a metallic ground peg before you fly (this is temporary though) or use Dyneema lines - they show a world of difference regarding electrical conductivity. (BTW i never really met anyone getting zapped but it's good to know i'm not alone
