Sorry to hijack the thread..but while we are talking about pointing and using the kite....I came up with an adjustable tack line while using the stock Nacra snuffer.
I simply attached a lead at the end of the hoop, then ran a line thru the back in to a cam-cleat on the front beam. The line was measured with a stop knot to adjust from about the distance as if it were tied, to about 4-6" out. Worked pretty good to give adjustment.
If you want to keep it simple, you can always guess the conditons, then tie of the tack accordingly before you sail.
