i sail with a stampede here in dunedin. i was on it 2 weeks ago in 20-40 (yes 40). it handled it very well (not saying it wasnt hairy as hell)...

needs some air to move, and sits a bit lower than boats with boards

reliable fun boat.. does NOT keep up with more modern boats in light air. parts are expensive (what boat parts aren't) but all in all a great boat
