Usually, when you come out of the calm spell, the wind comes in from the southwest. If you're west of the rhumb line, ease sheets and head for Bermuda. If you arrive at night, unless conditions are ideal, I advise standing off until you can enter Town Cut at St. George in daylight.
When leaving Bermuda to head for the States, wait until late May or early June. It's pretty much a matter of sailing a rhumb-line course, but try to ascertain what the Gulf Stream is doing. Often, there's a southeast meander, which is most useful to pick up if you're trying to place in the Newport-Bermuda Race. However, in 1975, when the Gulf Stream wasn't as well monitored as it is today, Iolaire, heading northwest, hit that wonderful southeastern meander, and in 24 hours of hard sailing, we made good only 40 miles. So obtain as much information about the Gulf Stream as you can before you leave. And take along a thermometer. Alongside the Stream are little cold eddies that break off spinning counterclockwise and warm eddies that spin clockwise. With the aid of a good navigator, a regular check on the water temperature and a little luck can speed you on your way through the Gulf Stream.
