We'd be doing a bit closer to the wind speed ;^)
This summer at about 4:00 AM, over 50 NM from Mt. Desert Island, ME we thought we were running out of fuel. The wind was about 2 or 3 knots -- wafting from generally behind us. We decided to not risk running out of fuel and trying to navigate through the currents and lobster pots in the approach to SW Harbor. So off went the Yanmar, most of the electronics, and up went the chute.
The wind stayed very variable and light until about 11:00 AM when it filled-in to about 6 knots (true) at about 130 degrees true to the rhumb line. Finally, about 10 miles out, it started to blow about 8 knots. Of course, the last 2 miles it verred to "on the nose" ;^( and strenthend to about 10 knots true. We arrived at about 3:00 at Dysert Marine in SW Harbor. Thank goodness for the 2,000 SF Asymetrical. It was really one of the nicest little sails because, after getting over the frustration of working hard to keep the boat moving at 2 knots or so, we really got to appreciate sailing.
During the sail, we hit a very big (maybe 5' or so fish) that they said was a basking Sunfish. I thought I'd hit a barrel ;^). We saw what looked like a whale swiming about 30 yards from us -- but it's tail fin was verical and it's dorsal fin was more than 12' or so from the tail. It clearly didn't need to surface to breath ;^).
