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.

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
- The breakwater and the harbor entrance, with the real wind shadow computed behind them.
- The main channel and basin geometry from NOAA electronic chart data.
- Red right returning: real IALA-B buoyage, placed where the chart puts it.
- Harbor traffic that teaches the actual right-of-way situations of this waterway.
IALA-B buoyage (red right returning).
What you can practice here
- The full curriculum: the tutorial, points of sail, buoyage, docking, gybes, and right-of-way, all set here.
- Docking approaches with no brakes, on sail and under power, until they are silk.
- Reading real puffs and lees on the water before your first lesson on the Bay.
- Free sail across the whole harbor, no clock.
