ASA 105 Advanced Navigation
ASA Class Description
Learn to apply the navigational theory and practices for safe navigation of a sailing vessel in coastal and inland waters. On-water coastal navigation skills elements are contained in the ASA 103 Basic Coastal Cruising, ASA 104 Bareboat Cruising, and ASA 106 Advanced Cruising & Seamanship, in progressively increasing levels of detail.
Prerequisites
ASA has no prerequisites for 105, but we teach it as an advanced navigation course to prepare you for ASA 106. As part of ASA 104, you'll attend a one-day Nav School to learn the fundamentals of classical navigation. Completing ASA 104 and Nav School sets you up for success in ASA 105.
ASA Recommendations
None.
Class Duration
This is a hybrid online and in-person class based in Lakeway, Texas. You can begin studying anytime and schedule your ASA 105 exam when you’re ready. You should plan to spend 60 - 80 hours studying the materials and 4 - 6 hours for the written exam.
OS Sailing Pathways Curriculum
ASA 105 is an advanced sailing class in Level III of the OS Sailing Pathways. This is a challenging class that requires attention to the details and precision. Once you pass the written exam, we sign your logbook, and you receive the ASA 105 certification.
As this is a classroom-only class, there are no required hours on the water. The skills you learn in ASA 105 will aid you in the navigation portions of ASA 103, 104, and 106.
Not Included In ASA Standard That We Teach
American Sailing's version focuses on Classical navigation primarily using analog methods (paper charts, dividers, parallel rulers, etc.).
Like all of our ASA courses, it goes beyond the standard curriculum — covering fundamentals of classical navigation, advanced classical navigation, and electronic navigation tools. The goal of this course is to have a full understanding of what the digital and electronic tools are doing on your behalf and be prepared to navigate successfully only using paper charts should the need arise.
