1. What is the most effective way to stop forward motion when
approaching a dock?
Increase throttle in forward
Shift to neutral and wait
Turn the wheel hard to starboard
Apply reverse thrust
Applying reverse thrust counteracts forward momentum and brings the
boat to a stop safely.
2. When docking a twin-screw catamaran, what advantage do you have?
Increased wind resistance
Faster acceleration
Independent engine control
, No need for lines
Independent control of each engine allows for precise maneuvering
without relying heavily on rudder input.
3. When should you use a spring line?
When drifting in open water
To control fore or aft motion at the dock
To anchor the boat
To tie to a mooring buoy
Spring lines are used to prevent the boat from moving forward or
backward along the dock.
4. What effect does prop walk have on a single-screw boat in reverse?
The boat moves sideways in forward
The stern moves sideways in reverse
The boat turns more easily
The engine stalls
Prop walk causes the stern to move laterally in reverse due to propeller
rotation direction.
5. What is the best approach angle when docking in calm conditions?
90 degrees
60 degrees
30 to 45 degrees
Parallel
,A 30 to 45-degree approach gives better visibility and allows easy
maneuvering and control.
6. What factor most affects docking maneuvers?
Fuel level
Wind and current
Passenger count
Paint condition
Wind and current exert strong lateral forces on a vessel and must be
accounted for.
7. What should be done before leaving the dock?
Turn on the bilge pump
Check lines and fenders
Lower the anchor
Fill the water tank
Proper line management and fender placement protect the boat and dock
during departure.
8. Which gear should be engaged briefly when backing a single-screw
boat to starboard?
Neutral
Reverse
Forward
Both forward and reverse
, Engaging reverse with a left-hand prop assists in walking the stern to
starboard.
9. Which knot is commonly used to secure a line to a dock cleat?
Bowline
Cleat hitch
Sheet bend
Square knot
The cleat hitch is quick and secure for tying lines to cleats.
10. When should you use fenders?
Only at sea
Only during anchoring
When docking or rafting
Never, they cause drag
Fenders protect the hull from contact damage while docking or rafted up.
11. What is the best method to account for a strong crosswind when
docking?
Dock with the wind
Ignore it
Approach at a steeper angle and use reverse to correct drift
Use full throttle
A steeper angle and timely reverse correct the boat’s sideways drift due to
crosswind.
