What’s the Difference Between ASA 101, 103, and 104? A Beginner’s Guide to Sailing Certification
If you’ve ever dreamed of learning to sail in the beautiful waters of the Pacific Northwest, you’ve probably come across a few acronyms such as ASA 101, ASA 103, ASA 104 and wondered what they mean. These numbers represent the American Sailing Association’s core certification levels, designed to take you from absolute beginner to confident coastal cruiser.
At Puget Sound Sailing Institute (PSSI), we offer all three levels at our marinas in Seattle, Tacoma, Des Moines, and Anacortes, helping students gain real world experience on Puget Sound’s diverse sailing conditions.
Let’s break down what each course includes and which one is right for you.
What Are ASA Certifications?
The American Sailing Association (ASA) offers a progressive training path that builds your sailing knowledge and experience in clearly defined stages. Each ASA course is nationally recognized and comes with a corresponding certification that proves you’ve mastered specific sailing skills.

If you’re brand new to sailing, ASA 101 is your starting point. This two-day, hands-on course teaches you how to safely operate a small keelboat during day sailing in familiar waters. You’ll learn sailing terminology, how sails work, how to steer and trim sails, and how to dock safely.
“This course is ideal if you’ve never sailed before or want to feel confident as crew on someone else’s boat.”
