Nick Hayes will build on the basics from Advanced Upwind Sail Trim and continue to refine your trim and rig knowledge‚ teaching with an emphasis on symmetrical and asymmetrical spinnakers and an introduction to “polars.” This is a great course for sailors with 2+ years of experience or who attend the Advanced Upwind Sail Trim class the week prior and for students with or seeking a rating for a “Tunable” boat like a J-24.
