So is the jibless (is that a word?) design used because it is easier to sail single-handedly?
The general design comes from working boats in the Cape Cod area. The simple rig and ease of handling along with clear decks and roomy hulls made them well suited to inshore fisheries.
The main reasons I have a Nonsuch are about the same. It’s a big comfortable boat that is easy to sail by myself.
The early bird gets the worm but its the second mouse that gets the cheese.
