1. What is the definition of "Angle of Attack"?
A) The angle between the mast and the deck
B) The angle at which the wind hits the sail
C) The angle of the boat's heel
D) The angle between the keel and the waterline
Answer B: The angle at which the wind hits the sail
Rationale: Angle of attack determines how effectively the sail generates lift; too high causes stalling.
2. The Center of Effort (CE) is defined as:
A) The pivot point around which the boat turns
B) The center of forces generated by the sails
C) The center of the boat's hull
D) The point where the rudder connects
Answer B: The center of forces generated by the sails
Rationale: CE is the centroid of all aerodynamic forces on the sails.
3. The Center of Lateral Resistance (CLR) is defined as:
A) The center of forces generated by the sails
B) The pivot point around which the boat turns (the geometric center of the underwater portion of the
hull)
,C) The center of the mast
D) The point where the keel meets the hull
Answer B: The pivot point around which the boat turns
Rationale: CLR is the centroid of all hydrodynamic forces on the underwater hull.
4. A boat will have weather helm if the CLR is:
A) Forward of the CE
B) Aft of the CE
C) Exactly aligned with the CE
D) Irrelevant to helm balance
Answer B: Aft of the CE
Rationale: When CE is aft of CLR, the stern pivots toward the wind, causing weather helm.
5. A boat will have lee helm if the CE is:
A) Forward of the CLR
B) Aft of the CLR
C) Exactly aligned with the CLR
D) Below the waterline
Answer A: Forward of the CLR
Rationale: When CE is forward of CLR, the boat pivots to leeward, causing lee helm.
6. Which helm condition is preferred for cruising sailboats?
A) Lee helm
B) Slight weather helm
C) Neutral helm
D) Strong weather helm
Answer B: Slight weather helm
,Rationale: Slight weather helm gives the helm "feel" and causes the boat to head slightly to windward in
gusts, self-feathering the sails.
7. Luffing the jib will (increase or decrease) lee helm?
A) Increase
B) Decrease
C) No effect
D) Depends on wind speed
Answer B: Decrease
Rationale: Reducing jib power moves CE aft, reducing lee helm.
8. Tightening the mainsheet will:
A) Increase weather helm
B) Decrease weather helm
C) Increase lee helm
D) No effect
Answer A: Increase weather helm
Rationale: Tightening the mainsheet increases mainsail power, moving CE aft and increasing weather
helm.
9. Moving weight toward the bow will (increase or decrease) weather helm?
A) Increase weather helm
B) Decrease weather helm
C) No effect
D) Decrease lee helm
Answer A: Increase weather helm
Rationale: Weight forward moves CLR forward relative to CE, increasing weather helm.
, 10. Reefing the mainsail will (increase or decrease) weather helm?
A) Increase
B) Decrease
C) No effect
D) Depends on the jib
Answer B: Decrease
Rationale: Reducing mainsail area moves CE forward, reducing weather helm.
11. Would you want more or less sail draft in light wind conditions?
A) Less draft
B) More draft (deeper sail)
C) No draft
D) Flat sail
Answer B: More draft (deeper sail)
Rationale: Deeper draft generates more power in light air.
12. Would you want more or less sail twist in very windy conditions?
A) More twist
B) Less twist
C) No twist
D) Depends on the point of sail
Answer A: More twist
Rationale: Twist allows the sail to spill power at the top, reducing heel and weather helm in strong
winds.
13. What does the cunningham do?
A) Controls the outhaul
