Harbors
Real harbors, playable.
Every Oh Sail harbor is built from real chart data: real geometry, real buoyage, real wind shadows. Generic water teaches generic sailing. A real harbor teaches yours.
Marina del Rey →
Home harborLos Angeles, California · IALA-B buoyage (red right returning)
Marina del Rey is where Oh Sail lives. Every lesson, from the first hoist to docking under power, is set inside a faithful model of this harbor, built from real NOAA chart data by a sailor who lives two miles from the breakwater.
San Diego Bay →
PlayableSan Diego, California · IALA-B buoyage (red right returning)
San Diego Bay is a working big-ship harbor with real channel discipline, and that is exactly what makes it worth practicing. Oh Sail carries a faithful bake of the bay from real chart data, playable in your browser.
Sydney Harbour →
PlayableSydney, Australia · IALA-A buoyage (colors reversed from the Americas)
Sydney Harbour is our first region-A harbor, and it exists partly to keep us honest: most of the sailing world does not run red right returning, and a teaching tool should know that.
Want your harbor next?
Every harbor is a real modeling job from real chart data, so we take them on one at a time. Clubs, schools, and community programs get first priority.
