Thanks Gary, you might`ave gone quicker if you lost the 100lbs of cargo and one of the 200lb men !

While the original topic is getting lost, I`ll add a deviation for the windsurfing supporters : Downwind Dash, Langebaan to Saldanha, Cape Town. Distance = 17km, record = 19minutes by Peter Slate. Average speed 53,6km/h, or 28,98 knots !!
Dean : Fascinating stuff, all those fantastic craft designed for the record, all claim to do double windspeed (but break up in more than 20knots). Thanks for the link.
Back to topic : Anyone else got some reasonably accurate data on average speed over a known distance ? (Gary, those guys who crossed the Atlantic must have been going real slow to average 7,9 knots, I managed that over a 4 day river trip on a Dart 18 with no spinnaker and 50kg of kit + crew, and we spent quite a bit of time just gliding gently in 3-5knot winds.) Then again it must be tough to always be in good breeze (and good mood)for 13 days. I would have eaten my crew by then.
