VeloceSailing 13 Posted December 7, 2021 Share Posted December 7, 2021 Only recently acquired a J80. The owner manual shows a polar diagram generated in 2000 which looks like this However I came across an extract of the owner manual from 2006 and the polar looks like this: The upwind performance of the second polar looks closer to a J/88s. Which one is right?? Quote Link to post Share on other sites
221J 32 Posted December 8, 2021 Share Posted December 8, 2021 The first one. 7 knots upwind is a stretch for a J/80. Enjoy your new boat. Quote Link to post Share on other sites
