A pretty good boat
For several years my brother trailer-sailed a Mac 21 on Tahoe, and I sailed there with him several times, including some races. He did the Trans-Tahoe race in that boat a number of times, once with me as crew. That boat is relatively easy to set up and launch (at one time he had the routine down to about 20 min each way,) and when you trailer-sail, that is the name of the game. If a boat is hard to launch or recover, you tend not to go after a few times. The boat has a drop keel and a small cabin, and he, his wife, and daughter sailed it for a week in the San Juans on two occasions. He and I overnighted it once at Emerald Bay on Tahoe. What I'm saying is that while its comforts are Spartan, it's a decent sailing boat that can handle most anything Tahoe can dish out (check the reports of the '04 race conditions), is easily trailered without using a bigger truck, is very affordable, and most of all, launches and recovers quickly. Hard to beat for that application.
