Play an AI-generated podcast conversation about this lesson

What is the primary factor causing a ship to drift sideways due to wind?

Heeling force

Following current

Strong engine power

Deep draft (correct)

How do deep draft vessels experience a greater effect from wind compared to shallower draft vessels?

They have a larger sail area

They are typically lighter ships

Their deeper immersion creates a larger surface area for wind to act upon (correct)

They have a higher center of gravity

What can high masted ships do to minimize heeling and maintain control in excessive winds?

Reduce sail area (reef sails) (correct)

Deploy anchors

Change course drastically

Increase engine power
