Thanks for all the responses.
In relatively small seas and 12-14 kts of wind, we are doing 5 kts or slightly faster, peaking at 5.5. As the wind comes up, I find that we heel a lot more, but are not going a lot faster.
I thought all the Hunters had a small headsail. The H49 comes with a 110 genoa. Our sales are far from new, but they are not in bad shape.
(The bottom is clean).
I appreciate Marc's comment. I tend to keep my main pretty flat. I am will leave it a little fuller next weekend and report back.
Thanks again.
