The Calypso 16' in the right hands and in its standard form could really get up and go. With a different sail plan and a spinnaker I think that you would find that it has a few good points of sail against an F16 (even with its extra weight and its "years") They were a cat that could be driven extremely hard off the wind. They suffered mostly to windward against other cats set up "purely as racers" but with its downwind potentual AND a kite, who knows??
