Oh Sail

Los Angeles, California · Home harbor

Marina del Rey, playable.

A free sailing simulator set in a faithful Marina del Rey: the breakwater, the main channel, the buoyage, and the wind shadows, built from real NOAA chart data. Learn to sail the harbor before you leave the dock.

Sailing a close reach inside the Marina del Rey breakwater, wind rose reading true and apparent

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.

That means the harbor you practice in is the harbor you will actually sail: the same entrance, the same channel, the same marks, and the same wind shadow off the breakwater that surprises every newcomer on their first beat out.


What’s modeled
