I think single-handing is fine and I have covered a lot of miles including going trans-Atlantic that way. The only trick is to do everything in a way that doesn’t require that you be in two places at the same time. Plan the flow of work so that things can either be done from one place or that all work can be done sequencely as you move about the boat.
The trickiest thing has been setting and recovering a spinnaker by myself with a close second being planning far enough ahead to allow for boat handling without an engine.
All the best,
hi, how do you go about setting and dousing a spinnaker by yourself? is this w/ or w/out a pole? is there any wind parameters you work w/in?
