Where Boats Anchor shows where boats actually stayed the night, and in what wind, at more than 12,000 anchorages in 62 countries.
Ask about a bay and get its nights by wind direction and strength: "Cane Garden Bay: boats stayed here 457 nights in E 10 kt or more, gusting 13.1 to 33.7 kt." Ask where to go tonight and it reads tonight's forecast at your position, then lists the nearby places where boats have stayed in every wind the night brings. Each answer links to the bay on the map.
