After looking at the Portsmouth ratings and taking the sails into consideration I think that the Dart 18 with a couple of modifications could be quite a giant killer.

Take the Rating of a Dart 18: 76.4
Add the Square Top Main (oversized): 0.98
Add Spinnaker: 0.96

Now multiply all that together:
76.4 X .98 X .96 = 71.9 (rounded)

This configuration will still [color:"red"]get[/color] time from a Hobie 18 (w/o chute) at 71.4. I cannot imagine this would not win a handicap race almost everytime.

Anyone have a Dart18 for sale? Kidding, I like Class racing too much I will stick with the Formula 18s, even at portsmouth of 62.4...Ouch! I think there are too many great sailors on this boat.

Later,
