My recent series of posts about the physics of sails has attracted some gentle ribbing from Joe while Bonnie in apparent admiration characterized it as "geeking out".
My own muddled musings on this subject - as much to try and get the issue straight in my own head as anything else - are nothing compared to the nerdy noodlings at this thread on Sailing Anarchy which is about the issue of whether you can construct a wind-powered craft that can sail dead downwind faster than the windspeed. You may think the answer is obvious but don't jump to conclusions until you have read all 1174 posts that have been made so far by geekier folk than me or any of my commenters, and still there is no consensus on the question.
If you feel compelled to add more geeky posts to the discussion on Dead Downwind please do it over at SA, not here. If you want to comment about SA or geeks (or idiots that go sailing their Lasers when the forecast is for rain, thunderstorms, floods and 35 knots) then feel free to do so here.
