You usually get a slower speed on one tack due to wave direction. One tack is always favored as you usually have the waves more head on.
I use the Selden mast tuning method as it can be done on any boat without special tools. You just need a metric ruler to adjust the shroud tension. http://www.seldenmast.com/files/595-540-E.pdf Chuck S, Resolute, 1990 C&C 34R > On August 20, 2019 at 9:53 AM Shawn Wright via CnC-List > <cnc-list@cnc-list.com> wrote: > > What are the symptoms of an uncentered mast?
