Design 1978 - Valiant

The following article is from Yankee magazine, circa 1971. It was written right in the middle of troubles with 12-meter Valiant.

Here's the article. That is some posed image of Olin. I'm surprised he sat for that. Please double click for zoom.

Olin readily admitted that he had relied too much on tank test data and pushed too hard to reduce wetted surface. There was clearly too little lateral area in the rudder. All I know is there are a lot of images of the quarter wave coming off the boat and various modifications tried to improve her. Take a look at the rudder profile in this sail plan.

And finally here's a look at the Valiant model in our office.
