Imray 100 Atlantic Routeing Chart. This is a routeing chart for yotties written by Don Street, and gives information for the Atlantic on currents and prevailing wind strength and direction for various months of the year. It is thus similar in subject to Adlard Coles's Atlantic Pilot Atlas, but does not cover every month of the year and is far less detailed and comprehensive. Still, a useful publication at an affordable price if you were just doing a one-off Atlantic crossing or circuit. It also includes te common routes, along with distance and bearings.
