a LOT cheaper than the US1M's and IOM's. Not quite as fast but much easier for a beginner. I had mine out yesterday in a serious blow and had a ball playing with tuning to get it to sail well in a big breeze (outhall, vang, backstay etc).

Down wind is a bit hairy when you try to round down w/o enough speed and the boat becomes a sub. Suddenly the rudder pops free as the bow goes down and it rounds up HARD.
