I think you had a touch more wind than we did (except for a brief 20 knots or so down by "the washing machine" at Sagres), but you may have noticed that while Alex's tackle is smoothly operating, you have to stare at his
line organizers for a few minutes to figure out what NOT to pull.
I did a two-hour watch at dawn alone and despite the near-absence of wind, I threw the engine into neutral and did some sailing using that mainsheet. It's actually pretty straightforward, but you have to be quick, not strong!
