What are the sea and wind conditions like where you are, and how agile are you?
If the answer to above is reasonably predictable with power boat chop no more than 2 to 3 feet at worst and winds under 15 knots, and you are reasonably agile (I'm 55 so no gymnast), then my experience is that the standard AI sail is just fine. As long as you fit an extension tiller and hiking straps and some kind of makeshift boom lashed to the mast, it's a very, very controllable package, and with the square topped sail it's very forgiving too, much more so than the boomed 35 sq ft bermuda sail with vang that I tried earlier, and a lot faster. Do however seal the mast with plumber's teflon tape at the joint and silicon elsewhere to ensure you don't go upside down if you flip and practice your re-entry technique - I've found raising the sail helps when I've practised (i'm a bit light at around 150 lb)
See my other posts on this forum for how I did it
