Stuvia
2. When docking a single-screw sailboat in reverse, what
effect does prop walk have?
A. Boat moves sideways in forward
B. Stern moves sideways in reverse
C. Boat goes straight back
D. Engine stalls
✔ B. Stern moves sideways in reverse — Prop walk pulls
the stern laterally based on prop rotation. Stuvia
3. What is the most challenging wind condition for docking?
A. Headwind
B. Tailwind
, C. Strong wind on the beam
D. No wind
✔ C. Strong wind on the beam — Beam wind pushes the
boat sideways, complicating alignment. Stuvia
4. When preparing to dock, what should be done first?
A. Start engine
B. Lower anchor
C. Rig fenders and dock lines

8. Which factor most affects docking maneuvers?
A. Fuel level
B. Wind and current
C. Passenger count
D. Paint condition
✔ B. Wind and current — Environmental forces must be
accounted for in all maneuvers. Stuvia
9. When docking into a headwind, which line should be
