I sailed with Frank Durant across the Gulf Stream on his Flicka last winter. Our trip was also uneventful until we got to Florida and hit a thunderstorm. The trip took 18 hours with a nice breeze and moderate seas. We motor sailed averaging a little over 4 knots. I suspect it would take a while longer in my M15, but given the right weather I think the boat would handle it just fine. Some amount of night sailing is necessary and maybe an entire night if speed is low. In my opinion one valuable piece of equipment for this passage is some kind of self steering setup. We had a Raymarine tiller pilot which broke part way across so we had to hand steer most of the way. This was not a problem with two of us to steer, but if I were single handling it would be very tedious and tiring to hand steer all the time. Frank has made the crossing a number of times in many different conditions. Maybe he'll chime in with a wild story or two. Rick M15 #337 Bluebird
