So this was a first, taking the boat cover off with actual frost on it and going for a sail.
Observations; fingers were cold and I need better gloves, particularly in light conditions where I’m not working hard and warming up. I switched to skiing gloves half way through which were good, though of course they would be useless if wet. I kept them dry.
I’ve added some more instrumentation to the boat in the form of extra tell tales and added leech tell tales where they’d worn out.
Looking at tell tales is nothing new to me, but having these extra ones really helps see airflow over the sail better.
