I weigh 180 lbs and I usually sail with my daughters who weigh 90 lbs and 80lbs. That is 350 lbs with no problems. The boat sails fine. It sails a bit slower than when I am soloing but still fun as we average 15mph to 20mph winds down here. The 14 has a 500 lb capacity limit. If you are not racing it will do fine. I have owned a 16 as well as a 14 and the 14 keeps up with the 16s that I sail with. I like the fact that it is light, easy to unload, and quick to set up. If you are planning to take adult friends out down the road, then you may want a 16, as they have an 800 lb capacity limit.
