OUPV Vessel Seamanship and Maneuvering 2

Question 1

What effect does prop walk have on a single-engine vessel when going astern?

Accepted Answer

The stern moves toward the direction of propeller rotation

Answer

Prop walk causes the stern to move in the direction the bottom of the propeller is rotating when in reverse, typically to port on a right-hand rotation propeller.

Question 2

What is the proper technique for approaching a dock in a crosswind pushing toward the dock?

Accepted Answer

Approach at a shallow angle, slow, and let the wind push the vessel alongside

Answer

When the wind is pushing toward the dock, approach at a shallow angle at slow speed, allowing the wind to set the vessel alongside gently.

Question 3

What is the turning circle of a vessel?

Accepted Answer

The path traced by a vessel from the time the rudder is put hard over until it returns to its original heading

Answer

The turning circle is the circular path traced by a vessels pivot point when the rudder is put hard over.

Question 4

How does trim affect a vessels handling characteristics?

Accepted Answer

Bow-heavy trim improves directional stability but reduces maneuverability; stern-heavy trim increases maneuverability but reduces stability

Answer

Trim significantly affects handling: bow-down trim tracks straighter but turns slowly; stern-down trim turns more easily but may be less directionally stable.

Question 5

What is the danger of following seas (waves from astern)?

Accepted Answer

Risk of broaching, pooping (waves breaking over the stern), or surfing out of control

Answer

Following seas can cause broaching, pooping, or surfing down wave faces with loss of steering control.
