Sails about as fast as a badly sailed F-18 FWIW
Agree with Yurdle, I sail one solo and also weigh 200 pounds. Except the three hands are not absolutely necessary. I mean, you could slow down to pull up the boards before hitting the beach... Getting out through surf solo is tough but can be done with the boards part way down. The boat sails on rails once you get in the groove. Steers easily, can become a little bit of a hand full in stronger breeze (like F6 plus), the transoms are not very buoyant so you need to watch where you put those 200 pounds.
Bad points are structural failure on older boats... You need to check if all the reinforcements in the bows are OK, listen while tapping bur preferably inspect with a small camera or something. On sandwich boats (after 1985 I believe) check around the beam mounts for delamination or softness.
Good is they are incredible bang for your buck if you pick up even a half way decent one.
