When I originally joined SEA, one of the first things I did was to go on a check-out sail with one of his classes. He seemed unfamiliar with the basic Rules of the Road, specifically that the vessel to leeward when two sailboats are on the same tack is stand-on and not the windward boat. I waited until after the class to point this out, but he argued with me about it. Apparently he didn't bother to look it up for months. When he did, he finally admitted he was wrong. Mind you, he had been teaching (and continues to teach) classes!
When not selected by the board (not just me) to be the program director (a position offered and accepted by Russ Huebschle), cancelled his commitment at the last minute to be the chef at SEA's annual SEAfood BBQ on Angel Island.
In addition, his wife (Tina Lewenhaupt) refused to release the graphics work she was doing on behalf of the organization. As a result, we had to scramble to find a new chef and recreate the logo graphics.
