PILOT CHARTS, FOUR WAYS

Paper Pilot Charts: Classic volumes are sold as a bound atlas, and are based on data going back to British Admiralty days, with one page for each month of the year; each book covers a major ocean region. Cornell’s Ocean Atlas:

This spiral-bound book organizes monthly pilot charts for portions of the world in which cruisers are likely to be interested: a succinct format that allows breadth of coverage, and data is based on more-recent trends. These were developed by Jimmy and Ivan Cornell.
