[Rhodes22-list] Campaigning a 175

Wally,
My complete agreement on this, although this can be risky in Bill's case. In my mind there is an added bonus when I want to sail with only the Genny. This was especially important when I had a conventional mast, or if I wanted to keep my BR cover over the boom. I now use IMF and have the BR cover up constantly, but on another horizontal pole. This Spring I will sail with and without main and be able to compare balance and speed factors that I can attribute to the main and will report back.
