San Diego Bay, playable.
Practice San Diego Bay in a free browser sailing simulator: a faithful channel from real chart data, real buoyage, and open free-sail. Learn the marks before you sail the bay.

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.
Switch to it from the location chip in the simulator and the marks, the channel, and the geometry are the real ones.
What’s modeled
- Channel and shoreline geometry baked from real chart data.
- IALA-B buoyage laid where the chart puts it.
- The same physics and coaching as the home harbor.
IALA-B buoyage (red right returning).
What you can practice here
- Channel transits and staying on the right side of the marks.
- Buoyage reading at speed: red right returning, for real.
- Free sail across the bay.
The structured lessons are set in Marina del Rey, our home harbor; San Diego is open water for practicing what they teach. If you sail the bay and want lessons set here, say so; harbor demand decides what we build next.
