For an ASA 104 Bareboat graduate, the San Francisco Bay has been an elite training ground. Navigating the Slot’s heavy breeze and the Central Bay’s complex currents has prepared you for more than just local weekenders; it has laid the foundation for global "island hopping" in destinations like the Caribbean, the Mediterranean, and beyond.
But there is a distinct line between coastal cruising and the raw, rhythmic endurance of the open ocean. To transition from a coastal skipper to an offshore passage-maker, you must evolve. Our September 7 – 13 ASA 108 Offshore Passagemaking course is the final summit. To get there, you need to bridge the gap this summer with two critical evolutions: one of the mind, and one of the helm.
1. The Navigation Mindset: ASA 105 Coastal Navigation
Scheduled Dates: July 21 – 30
Before you leave the sight of land, you must know how to confidently plan multi-day routes, and handle the ever-changing conditions of coastal waters. ASA 105 is where you stop being a passenger to your GPS and start becomin a true navigator. You’ll learn manual plotting, tide calculations, and the USCG Navigation Rules. Learn more about ASA 105 fundamentals required for the ASA 108 and 107/117 prerequisites.
2. The Experience: ASA 106 Advanced Coastal Cruising
Availability: May 14 – 17 (Only 2 spots left!) | June 04 – 07 (Only 2 spots left!)
This is where the theory hits the water. If ASA 104 teaches you how to manage a boat, ASA 106 teaches you how to manage a voyage. This advanced coastal course is a rigorous liveaboard passage leaving the protected waters of the SF Bay, designed to test you in any conditions, day or night, at anchorage or underway. What you’ll learn in 106:
- Night Operations: Stand a navigation watch for at least 20 miles under the stars.
- Heavy Weather & Engineering: Troubleshooting engine issues (from fuel lines to electrical) and managing sail trim in 20+ knots of wind.
- Advanced Seamanship: Anchoring as a team and refined sail theory to balance weather helm.

Flexible Pathways:
At Modern Sailing, you can dive into the physical challenge of ASA 106 before completing your ASA 105 theory. You have up to one year after completing an on-water course (ASA 106 Advanced Coastal Cruising or ASA 108 Offshore Passagemaking) to finish the required navigation theory (ASA 105 Coastal Navigation or ASA 107 Celestial Navigation/ASA 117 Basic Celestial Endorsement) and receive both certifications.

The ASA 108 Offshore Passagemaking course is the pinnacle of the ASA curriculum.
The Pathways
On the Water: ASA 104 Bareboat Cruising → ASA 106 Advanced Coastal Cruising (Complete ASA 105 within 1 year of finishing 106)
Navigation: ASA 105 Coastal Navigation → ASA 117 or 107 (If you complete ASA 105 and 106, you may enroll in ASA 108 based on your resume).
