I've had my FX-1 out with two and had no problems whatsoever. The boat handles the same, just a slight decrease in the acceleration is all I've noticed. I weigh about 190lbs and have no trouble at all with righting, it comes up in no time. The person I bought it from weighed about 165 lbs and he reported little trouble righting it as well.

While I think being able to right a boat is critical, most boats can be righted with one person. I had a TheMightyHobie18 before the FX-1 and could do it myself as well with an adaptive device. Hooking it up took about 2 minutes, so total time to right was about 5 minutes. Again, righting the boat is critical, but I think more critical is finding the right boat for you. You will spend much more time upright than sideways, so find a boat you like to sail....then figure out a way to make it work. There are plenty of devices out there to help you.

The FX-1 is a really fun boat. I have not sailed an I17, so I cannot compare, but I have a blast on my boat. The acceleration is great, upwind speed is good and once the chute is up......see ya later! I can rig the boat myself with little trouble and it's light enough to move on the beach myself as well.

My wife and I will be racing together later this year and if you wish, I can let you know how it goes. So far this year, I've raced solo and done very well. A lot of the fun for me is figuring out the new boat and dialing it in. If you have any questions, just let me know! Good luck in finding the right boat for you.
