Murph,
Interesting, and yes, having the float on the top of the mast would prevent it from turtling. The latter is what happened when my nephew was sailing one. I can't remember if he was sailing alone or not.
I now sail a fairly large monohull almost always alone, and it has 2,500 pounds of lead in the keel, so it won't go over. I also don't make the mistake of putting up too much sail--it has a furling genoa so I can adjust it from the helm if things start to blow. Frankly, it's exciting enough for me at my age, but there's nothing quite like the speed and excitement of a Hobie or Laser in a 15-knot wind. You really never get that on a large yacht, except maybe on those big racing catamarans.
Have fun. It's a great sport.
Alan
