I can see how reefing would be nice for solo sailing. However, I almost always sail 2-up and have never reefed a H16 sail. Since the mid-80s the sails have been built without the reef points and the halyard has only one stop, so it is kind of academic.

Fun Fact: The Worrell 1000 logo (boat going through the surf) is a H16 with a reefed main.
