Deep dive into professional navigation skillsTraditional AND electronic navigation masterySelf-study flexibility with on-board examinationBundled with ASA 106 in Advanced courses

GPS can fail. Electronics can die. Weather can close in. When they do, the navigator who understands the fundamentals will still know where they are. ASA 105 Coastal Navigation gives you those fundamentals.

This is primarily a self-study certification — you'll work through the course material at home and take the exam onboard during your sailing course. But the knowledge is anything but theoretical. You'll learn to read charts like a seasoned captain, convert between true and magnetic bearings instantly, and plan passages that account for tides, currents, and conditions.

At Sailing Virgins, we bundle ASA 105 with ASA 106 in our Advanced courses. The theory you learn in ASA 105 directly supports the practical skills you'll demonstrate in ASA 106. Together, they prepare you for professional-level sailing.

The navigator doesn't just know where the boat is. They know where it's been, where it's going, and what lies between. That's ASA 105.

What You'll Master in ASA 105

Nautical Chart Mastery

Understand every symbol, color, and notation on a nautical chart. Read the water before you see it.

Dead Reckoning

Real Talk

We Get It. Booking Can Feel Scary.

Every week, students arrive with the same worries. Here's the honest truth about what to expect.

The Solo Traveler Manifesto

Here's a secret: most people who book with us are solo travelers. They come alone but leave with lifelong friends. Living on a boat for a week creates bonds that typical vacations never could.

By day two, you'll forget you arrived alone. You'll be laughing over breakfast, cheering each other on during sail training, and sharing stories under the stars. Our small crew size (4-6 students) means everyone connects.

Many of our students have traveled the world solo—but they say a Sailing Virgins trip is where they've made their deepest friendships. There's something about the sea that strips away pretense.

I was terrified to show up alone. By day three, I was planning our reunion trip.
