ASA 103 — Basic Coastal Cruising (American Sailing)

The ASA 103 Basic Coastal Cruising standard (American Sailing) prepares sailors to skipper a sloop‑rigged, auxiliary‑powered keelboat (~25–35 ft) by day in moderate coastal conditions. It covers cruising terminology, boat systems, engine operation, docking, intermediate sail trim, navigation rules and basic coastal navigation, anchoring, weather interpretation, safety and seamanship. Certification requires demonstration of written and on‑water skills against the ASA 103 standards.

About this course

ASA 103, Basic Coastal Cruising, is an intermediate certification standard owned and published by American Sailing (formerly the American Sailing Association). The standard builds on Basic Keelboat skills and teaches the cruising fundamentals needed to skipper larger boats on coastal and inland waters: cruise preparation and planning, terminology, safety equipment and procedures, boat systems and auxiliary engine operation, docking and anchoring, sail combinations and reefing, basic coastal navigation and chart work, applicable Navigation Rules, crew management and seamanship, and weather interpretation. Completion requires demonstration of the course's published skills on the water and passing the ASA written exam for 103; schools teach to the ASA 103 certification standards and award the ASA 103 certificate on successful assessment.
