I'm stunned at the "complexity" in the procedure...having never set/doused/sailed a spinny cat before, my crew & I hdid a whole regatta (6 races) of flawless sets/douses on my Tornado. This was with a mid-pole Guck Skunk snuffer. Never shrimped, run over with bow, wrapped a sheet. All we do is take up a little slack on the douse line, blow the halyard, snuff, snuff, snuff, then blow the tack line as sail is gathered in. Maybe on the T boat, things are less hairy cuz of the extra beam and the mid-pole setup.
