Re: Flying the Gennaker
I was doing this in light air on a small lake in light air in summer when the wind doesn't suddenly change that dramatically around here. The asym also had a sock, which made it easy to douse. Sorry about not including all of that information and I do take your warnings to heart in more dynamic weather.
We ran without the main a couple of times because it made it easier to see the whole sail and to learn how to trim and gybe it. Once we became comfortable with those operations without a main we started to fly it with the main.
boats that I sail on regularly: Pearson 28-2, Rondar 505, Yankee 30, Blanchard Junior
