Thanks again, Schnool and ShockT.
I can see the mast bend - mainly the top half. I had to measure it when ordering a new main-order mainsail a few years back.
I think I'm basically up-to-speed on the theory now, and need mileage to turn that into practice. Getting the crew "on-board" will require "firm but nuanced" skippering.
There's for sure an art to this as much as a science, and I know to pay attention to both.
