Hi Chuck, and thanks. Regarding a rope clutch, my asym will be hoisted, furled, on its top-down furler at the dock before heading out, and will stay hoisted the whole time (either furled up, or unfurled). So there will be no hoisting and dousing of the asym while on the water. I’ve got a cam cleat on the starboard cabintop side, basically at the cockpit coaming, which was for my pole down line. I’m hoping it will be sufficient for the asym tack line.
And yes I think the asym will be a lot easier to fly at Chatfield than the symmetrical. In addition to shifty wind, we have short legs, and I really got tired of busting my ass on the foredeck, schlepping that big spinnaker pole around every few minutes when we needed to set, gybe, or douse. It was hard work. Cheers, Randy > On Jul 11, 2022, at 2:13 PM, Novabraid via CnC-List <cnc-list@cnc-list.com> > wrote: > > Randy, > I found it to be very important to have a clutch for the tack line.
