Question 1

When manoeuvring a small vessel in reverse, which side does a single right-hand propeller typically cause the stern to walk toward?

Accepted Answer

Port (left)

Answer

A right-hand (clockwise) propeller in reverse causes the stern to walk to port due to propeller torque and the paddle-wheel effect acting on the lower blade, which has greater bite.

Question 2

What is the safest approach angle when coming alongside a dock in calm conditions?

Accepted Answer

30 degrees, reducing to near-parallel

Answer

A 30-degree approach lets you control speed and pivot the stern in at the last moment with a burst of reverse or a spring line. Steeper angles risk a broadside collision; too shallow reduces control.

Question 3

When must an operator use a kill switch (engine cut-off) lanyard?

Accepted Answer

Whenever the operator is the only person aboard or when required by the vessel's design

Answer

Transport Canada requires operators to use a kill switch lanyard whenever it is provided and when they could be thrown from the helm, preventing a runaway vessel after a fall overboard.

Question 4

What effect does shallow water have on a vessel's handling?

Accepted Answer

Squat increases, stern sinks, steering becomes sluggish

Answer

In shallow water, flow is restricted under the hull, causing the bow to rise slightly and the stern to squat. Steering response deteriorates and the vessel may be drawn toward the bank (bank effect).

Question 5

What is the purpose of a spring line when berthing?

Accepted Answer

To prevent the vessel from moving forward or backward along the dock

Answer

A spring line runs at an angle forward or aft along the dock and prevents the vessel from surging ahead or dropping astern while alongside, complementing breast lines that hold it laterally.
