Boating Certification Test Boat Operation & Maneuvering 2

Question 1

When docking a single-engine outboard boat with a right-hand propeller, you should approach the dock from which direction to use prop walk to your advantage?

Accepted Answer

Starboard side

Answer

A right-hand propeller in reverse pulls the stern to port, so approaching with the dock on the starboard side lets prop walk assist in docking.

Question 2

What is the recommended technique for making a sharp turn at low speed in a powerboat?

Accepted Answer

Turn the wheel hard and apply a brief burst of forward throttle

Answer

A brief burst of forward throttle while turning hard provides water flow over the rudder or steering mechanism, improving turning response at low speed.

Question 3

When operating in a narrow channel, a vessel should keep to which side of the channel?

Accepted Answer

The starboard (right) side

Answer

Rule 9 of the COLREGS requires vessels in narrow channels to keep as far to the starboard side of the channel as is safe and practicable.

Question 4

What is 'cavitation' in the context of boat propulsion?

Accepted Answer

Formation of vapor bubbles on the propeller blades that collapse and cause damage

Answer

Cavitation occurs when low pressure on the propeller blade causes water to vaporize, forming bubbles that implode and erode the propeller surface.

Question 5

You are traveling upstream on a river and meet a downbound vessel. Which vessel has the right of way?

Accepted Answer

The downbound vessel, because it has less maneuverability due to the current

Answer

Vessels proceeding downstream (downbound) with a following current have restricted maneuverability and are given right of way over upbound vessels on rivers.
