Data are collected from the YOTREPS network of cruising yachts worldwide and plotted with Esri ArcGIS 10.2.1. Density of yacht traffic is highest in red. Note the seasonal patterns of transits in the various oceans: high density of traffic during the ''Coconut Milk Run'' in the Pacific beginning in April, eastward Atlantic ocean traffic during the boreal summer and westward during the boreal winter, and passages to Alaska in the heart of the boreal summer.
