Questions and Answers

What factor primarily causes a ship to drift sideways due to wind?

  • Deep draft (correct)
  • Following current
  • Heeling force
  • Strong engine power
  • How do deep draft vessels experience a greater effect from wind compared to shallower draft vessels?

  • They have a higher center of gravity
  • They are typically lighter ships
  • Their deeper immersion creates a larger surface area for wind to act upon (correct)
  • They have a larger sail area
  • What can high masted ships do to minimize heeling and maintain control in excessive winds?

  • Reduce sail area (reef sails) (correct)
  • Increase engine power
  • Deploy anchors
  • Change course drastically
  • How does a following current affect a ship's speed?
