I have a H17Sport and used to weigh upwards of 230 lbs and mostly solo. On occasion I take along a passanger and our combined weight could be as much as 450 lbs. You can really tell the performance falls off with the increased weight, but the boat still sails well. The wings are rated 350 lbs and I usually try not to exceed that. Previously I owned a H16 (20 yrs) and have sailed Bravos, Waves and Getaways. Of the group, the H17Sport is by far my favorite. It is the fastest of the group and performs the best in high wind. Waves are no real problem when soloing. I've sailed in conditions with tight 5+ ft waves and with proper weight distribution have had no problems. With 2 on the boat you do have to back off a little on beam/broad reaches so not to pitchpole, but otherwise there is plenty of flotation.
