Re: Comparing Upwind Performance / Tacking Angles
One real-world data point:
I recently analyzed upwind GPS data for my GS 41 from two different races in Chesapeake bay. Best overall tacking angle (true, based on COG, so including leeway, etc., not 'pointing angle') was 110.6 degrees. average more like 115 degrees. The two race average helps remove effects of current.
A lot of this result is based on wide sheeting angles on the GS, with sails cut for that. But, I was racing in a mixed fleet of similar era boats. Only a few were able to significantly outpoint us.
