What the ASA 101 knowledge standard covers

American Sailing publishes the ASA 101 standard openly. Its knowledge elements cover sailing terminology (boat parts, sails and their controls, directions), maneuvers and points of sail with the helm commands, the Navigation Rules for a 25-foot sailing vessel, US aids to navigation, and safety gear and procedures. The skills elements — sailing each point of sail, tacking, jibing, crew overboard, docking and the six knots — are assessed on the water.

This sample takes one or two questions from each knowledge area. Use the result to find the area to revisit, then read the study guide for the full topic checklist and a seven-day plan.

1

Terminology

Hull, deck, keel, rudder, standing and running rigging; the sails and their corners and edges; port, starboard, windward and leeward.

2

Maneuvers and points of sail

The no-sail zone, close-hauled to run, port and starboard tack, tacking, jibing, sailing by the lee, and the commands “Ready to tack” — “Ready” — “Hard alee”.

3

Navigation Rules

Look-out, sail against sail on different and same tacks, overtaking, power head-on and crossing, sail crossing power, and behaviour near commercial traffic.

4

Aids and safety

Lateral marks by color, shape and number, safe water and special marks; federally required equipment, navigation lights, float plans, accident reporting and the BAC limit.
