1. What is weather helm? - Correct Answer: The boat's tendency to head
up into the wind on its own. A slight amount is desirable for 'feel.' Excessive
weather helm indicates overpowering.
2. What is lee helm? - Correct Answer: The boat's tendency to bear away
from the wind on its own. Unsafe — in a knockdown, the boat jibes instead
of rounding up.
3. What is reefing? - Correct Answer: Reducing sail area by partially
lowering and bundling the sail along the boom. Reduces heel and
overpowering. Reef early — before conditions demand it.
4. What is heaving-to? - Correct Answer: A near-stationary resting position
created by backing the jib, easing the mainsheet, and putting the tiller to
leeward. The opposed forces balance the boat to nearly a stop.
5. Name the four dock lines and what each prevents. - Correct Answer:
Bow line (bow from swinging away) · Stern line (stern from swinging away) ·
, Forward spring (prevents aft movement) · Aft spring (prevents forward
movement).
6. What are fenders used for? - Correct Answer: Inflatable cushions hung
from lifelines to protect the hull from contact with the dock or other boats.
7. What is the ideal point of sail to approach a mooring or dock under sail? -
Correct Answer: Close reach — allows the helmsman to ease sheets to
decelerate on final approach and have maximum boat control.
8. Name the six essential sailing knots and each knot's primary use. -
Correct Answer: Bowline (non-slip loop) · Figure-eight (stopper) · Cleat hitch
(horn cleat) · Clove hitch (temp piling/fenders) · Round turn & 2HH (secure
piling) · Rolling hitch (line under load).
9. What is the bowline's main advantage? - Correct Answer: It creates a
non-slipping loop that will NOT jam under load and is easy to untie even
after heavy loading. The most useful sailing knot.
10.What does a cleat hitch locking tuck do? - Correct Answer: The final
half-hitch is flipped so the loop goes under itself — this 'locks' the cleat
hitch so it can't accidentally release, while still being quick to undo.
11.What is the rolling hitch used for? - Correct Answer: Tying a line to
another line that is under load — particularly for relieving a jammed winch.
Grips in one direction only (toward the load).
, 12.What does a masthead fly indicate? - Correct Answer: The apparent
wind direction at the top of the mast. The arrow's tail pointing inside the 'V'
shape means you're in the no-sail zone (in irons).
13.What are telltales used for? - Correct Answer: Pieces of yarn/ribbon on
the sail luff that indicate airflow. Both streaming aft = correct trim.
Windward lifting = pinching or over-trimmed. Leeward lifting = under-
trimmed.
14.What is draft in a sail? - Correct Answer: The depth or curvature of the
sail's cross-section — how 'full' or 'flat' the sail is. More draft = more power.
Less draft = less power, better in strong wind.
15.What is LOA vs. LWL? - Correct Answer: LOA (Length Overall) = full bow-
to-stern length. LWL (Length on Waterline) = actual waterline length —
determines hull speed formula: √LWL × 1.34 knots.
16.What is draft (of a boat)? - Correct Answer: The depth from the
waterline to the bottom of the keel. Critical for determining the minimum
water depth the boat needs to avoid going aground.
17.What is freeboard? - Correct Answer: The height of the hull above the
waterline. High freeboard = drier in waves. Also used in scope calculations
(depth + freeboard = total depth for scope formula).
18.What is the difference between forestay and backstay? - Correct
Answer: Forestay runs from masthead to bow — supports mast forward and
