good to get the cobwebs off this aircraft. a few short flights with a trip to the flying j ranch and back. as usual, el mirage is like a light switch. wind was completely off for all launches and landings until the last landing when there were lots of dust devils (in advance of a front). the landing went fine and juan helped me get the glider to our camp and broken down in all the gusty-ness. great trip, great company. el mirage is a special place.

Next time you go land sailing, let me invite myself along. I want to "tack downwind."

But the apparent wind changes with change in heading, more so the faster you're travelling. So let's say you're on a broad reach 135 degrees off true wind, apparent wind 10 degrees off the bow... if you turn 10 degrees into the apparent wind, are you now heading directly into the apparent wind? I think not. Apparent wind will screw around with you until you cross true wind, and perform your tack. Unless you're in a huge sliding turn, which can't last for long.

Still a jibe turkey. Razz

I had trouble understanding the concept too. I'm a water sailor. Land sailing has a bunch of weird things happen going that fast. They tack down wind, or don't tack at all. The apparent wind can be any angle you want when you are going 4X the speed of the wind.

To further hurt your brain. This thing is directly down wind, faster than the wind : https://www.youtube.com/watch?v=5CcgmpBGSCI
