ASA 101 Basic Keelboat Sailing Exam
Questions & RATIONALES LATEST UPDATE
THIS YEAR
ASA 101 Basic Keelboat Sailing Exam – Summarized Point-Form Coverage
Boat Anatomy & Terminology – Hull, deck, cockpit, cabin, transom, bow, stern, port, starboard,
beam, freeboard, draft
Underwater Appendages – Keel (ballast stability, lateral resistance against leeway), rudder
(steering control), tiller vs. wheel, skeg
Mast & Rigging – Mast (vertical spar supporting sails), boom (horizontal spar at foot of
mainsail), gooseneck (boom-to-mast connection), spreaders, shrouds, stays (headstay/forestay,
backstay), standing rigging (fixed support) vs. running rigging (adjustable lines)
Sails & Sail Parts – Mainsail, headsail/jib, sail edges (luff, leech, foot), corners (head, tack, clew),
battens, telltales (wind indicators)
Running Rigging & Deck Hardware – Halyards (raise sails), sheets (trim/control sails), outhaul,
boom vang, cunningham, traveler, winches, cleats, blocks, fairleads, fenders, docklines
Points of Sail – No-Go Zone (approximately 45° either side of wind), close-hauled (beating,
highest pointing), close reach, beam reach (fastest, wind abeam), broad reach, running (dead
downwind), tacking vs. jibing
Wind Concepts – True wind vs. apparent wind, windward (toward wind) vs. leeward (away from
wind), lift generated by airflow over sails
Sail Trim & Controls – Trim (adjust sail angle via sheets), ease (let out), haul in (pull in), telltale
tuning (flow attached vs. stalled), draft control via outhaul, halyard tension, cunningham, boom
vang
Maneuvers – Tacking (turning bow through wind), jibing (turning stern through wind), heaving-
to (stopping/holding position), docking/undocking, mooring, anchoring, crew overboard
recovery
Navigation Rules (COLREGS) – Stand-on vs. give-way vessels, sailboat vs. powerboat rules,
same tack vs. opposite tack, overtaking, head-on, crossing situations, sound signals, restricted
visibility
Aids to Navigation – Buoyage system (red right returning), lateral marks, safe water marks,
isolated danger marks, special marks, daymarks, lights, ranges
Safety Equipment – PFDs/life jackets (Type I, II, III, V), visual distress signals (flares, flags),
sound-producing devices (horn, whistle, bell), fire extinguishers, navigation lights, VHF radio,
anchor and rode
,Page 2 of 173
Emergency Procedures – Man overboard (MOB) recovery (quick-stop, figure-eight, reach-and-
return methods), fire response, flooding/damage control, distress calls (Mayday, Pan-Pan,
Securité), abandon-ship procedures
Seamanship & Knots – Bowline (king of knots, non-slip loop), cleat hitch (securing to cleat),
clove hitch, figure-eight, square knot, reef knot, sheet bend
Weather & Sea Conditions – Wind speed estimation (Beaufort scale), reading weather
forecasts, recognizing approaching storms, heavy-weather sailing techniques (reefing, heaving-
to, running before storm)
SECTION 1: BOAT ANATOMY & TERMINOLOGY (Questions 1-50)
Question 1: A student sailor is describing the front of the boat to their instructor. What is the
proper term for the forward part of a boat's hull?
A) Stern
B) Port quarter
C) Bow
D) Beam
Correct Answer: C
Rationale: The bow is the forward end of the hull. The stern is the aft end, the port quarter is the
aft left side, and the beam is the widest part of the hull.

Question 2: During a sailing lesson, the instructor asks which side of the boat is "port." What is
the correct response?
A) The right side when facing forward
B) The left side when facing forward
C) The rear side
D) The front side
Correct Answer: B
Rationale: Port is the left-hand side of the vessel when facing forward (toward the bow). It is
marked with a red navigation light. A helpful memory aid is that "port" and "left" both have four
letters.
Question 3: The instructor points to the right side of the boat and asks for its name. What is the
correct term?
, Page 4 of 173
A) Port
B) Starboard
C) Stern
D) Bow
Correct Answer: B
Rationale: Starboard is the right-hand side of the vessel when facing forward (toward the bow).
It is marked with a green navigation light.
Question 4: A sailor is explaining the function of the weighted fin at the bottom of the boat.
What is this component called and what does it do?
A) Rudder – provides steering control
B) Keel – provides stability and prevents sideways drift
C) Centerboard – provides storage space
D) Daggerboard – increases speed
