How do you let out/ease a mainsail?

BTW, “halyard” could also be classified as a “haul” since the first part derives from the verb “to haul”.

This is not necessarily true, at least not with dinghies, and maybe larger boats with small headsails.

And single handed on small ocean sailing boats, you double sheet both sides so you can do inside the stays and outside without having to go to the foredeck in bad weather. Especially storm jibs where you go from beam reach to hard on the wind quickly and must keep steerage way.

Wise to do that in tight quarters with light winds also.
