On mine, I said
UPWIND IN 40 KNOTS
The simple, forgiving rig, very high
righting moment, shelter on the windward side and lack of things to
worry about should make it as easy as possible for the crew. The large,
twin rudders and schooner rig give excellent, low stress control at low
speed with no flogging sails or sheets. Windows in the cuddy allow a
seamanlike lookout to be kept without exposing the crew. Shunting
really comes into it's own in these conditions, particularly if there
are big waves as well.
Use what you like, but probably diplomatic not to use an exact copy. I explained about simple forgiving rig, lack of worry, etc elsewhere.

Part of the wooden boat design competition is the ability for the design to sail to windward in a gale. How can you prove that from a drawing? I am pretty sure that my design will float, and it should be fast, but I don't know how to calculate upwind performance in heavy weather. Can anyone tell me what criteria might be used to judge that?- Gardner
