ASA 106 – ADVANCED COASTAL CRUISING EXAM
COMPLETE PRACTICE QUESTIONS
2026–2027 UPDATED CURRICULUM
1. What is the primary reason for rigging a jackline on deck during
offshore passages?
A. To provide a secure point to attach sail control lines
B. To enable crew members to clip on safety harness tethers while
moving on deck
C. To hoist the national ensign
D. To serve as an additional lifeline for hanging fenders
Correct Answer: B. To enable crew members to clip on safety harness
tethers while moving on deck
Rationale: Jacklines are strong lines or webbing run along the deck to
which crew members attach their safety harness tethers. This allows
them to move about the deck while remaining connected to the vessel,
a critical heavy-weather precaution to prevent man overboard .
2. When a vessel is "hove to," what is its general state?
A. It is anchored with two anchors set to reduce swinging
B. It is secured alongside a dock with spring lines
C. It is stopped and maintaining a nearly stationary position under sail
D. It is sailing with all sails furled and relying solely on engine power
Correct Answer: C. It is stopped and maintaining a nearly stationary
position under sail
,Rationale: Heaving to is a heavy-weather tactic used to stop a vessel's
forward progress and hold a steady, safe position. It is accomplished by
backing the jib and lashing the tiller or wheel to leeward, allowing the
boat to lie at a comfortable angle to the wind and waves .
3. What does a falling barometer generally indicate?
A. An approaching high-pressure system and improving weather
B. Stable and fair weather conditions
C. Deteriorating weather with a potential for storms
D. A drop in sea level due to tidal changes
Correct Answer: C. Deteriorating weather with a potential for storms
Rationale: A falling barometer indicates that atmospheric pressure is
decreasing, which typically signifies the approach of a low-pressure
system and associated unsettled weather, including wind and
precipitation .
4. What is the primary purpose of a storm trysail?
A. To increase boat speed in light winds
B. To act as a primary sail for downwind sailing
C. To provide a small, strong sail for steering and control in heavy
weather
D. To serve as an emergency blanket for crew members
Correct Answer: C. To provide a small, strong sail for steering and
control in heavy weather
,Rationale: A storm trysail is a very small, heavy-duty sail designed to be
used in severe storm conditions. It is attached to a separate track on the
mast, not the boom, and its small size allows the boat to maintain
steerageway while being manageable in extreme winds .
5. Which of the following is the most effective method for recovering a
fouled anchor?
A. Increase engine power to full throttle to break it free
B. Ignore the problem and cut the anchor line
C. Motor in circles while pulling on the anchor rode
D. Use a sentinel or trip line attached to the anchor's crown
Correct Answer: C. Motor in circles while pulling on the anchor rode
Rationale: Sailing or motoring in a circle while pulling on the anchor
rode can change the angle of pull and often helps to work the anchor
free from obstructions. Other methods include using a trip line to pull
the anchor out backward .
6. What is the correct interpretation of a "weather helm"?
A. The boat has a tendency to turn into the wind
B. The boat has a tendency to turn away from the wind
C. The boat is perfectly balanced and sails straight with no helm input
D. The boat is sailing with a reefed mainsail
Correct Answer: A. The boat has a tendency to turn into the wind
Rationale: Weather helm is the tendency of a sailboat to turn its bow
into the wind. A slight amount of weather helm is generally considered
, desirable for safety, but excessive weather helm is inefficient and
requires constant correction .
7. When anchoring with a stern line secured to the shore, what is the
primary risk?
A. The anchor will not set properly
B. The boat may swing into the wind and current
C. You may become trapped against the shore if the wind shifts
D. The stern line will chafe and break
Correct Answer: C. You may become trapped against the shore if the
wind shifts
Rationale: Securing a boat by the stern to the shore with a bow anchor
holds the vessel in a fixed position. If the wind shifts 180 degrees, the
boat can be blown against the shore, potentially running aground or
causing damage .
8. What is the primary cause of electrolysis in a boat's underwater
metal parts?
A. The natural corrosion of aluminum in saltwater
B. A stray electrical current in the water, often from shore power
C. The chemical reaction of seawater with the paint
D. The rubbing of the hull against the dock
Correct Answer: B. A stray electrical current in the water, often from
shore power
