Third Edition. This classic planning guide is now well into its second century and is still depended upon by bluewater cruisers to assist their route planning. Each ocean or main sea area is dealt with in a separate chapter with recommended routes, and seasonal current and weather conditions. Includes a number of small charts in full color showing principle ocean routes and world charts of climate and ocean currents. For those who wish to supplement Jimmy Cornell’s “World Cruising Routes” with much more detail on weather and ocean conditions.
