Oh yeah... definitely better than a Hobie 16. The hulls have really good volume and you can drive it pretty hard. I've dug the hulls down to the front beam and as soon as I depower they will pop right back up. I never flipped my 5.2 because I was afraid I could not right it, so I always sailed conservatively and with other boats around. I weigh about 170 lbs and could have probably righted it with a large bag.
I sold it a while ago and have regretted it ever since. Now I'm having trouble budgeting in another boat, but I'm still looking. I'm hoping to get into a good used Nacra 18 Square but they seem to be pretty rare.
