Sailing Routes

Playing with Google Earth. Here's what the two voyages we have in mind look like from way up high! (click on pic to embigify)

Run from Antigua to Bermuda is about 930 nm and from Bermuda to Hailifax is about 730 nm. Let's see. . . .

930 nm/5 knots = 186 hours or 7.75 days.
730 nm/5 knots = 146 hours or 6 days.

Can we maintain or average 5 knots? How much motoring will there be. Fuel? We can't lollygag out there forever as there is the occasional hurricane. (Don't say hurricane!)
