The video tutorial explains how to use vectors to determine the speed and direction of a boat affected by a current. It covers the basics of bearings, vector representation, and the calculation of resultant vectors. The tutorial demonstrates how to convert bearings to angles, perform vector addition, and calculate the magnitude and direction of the resultant vector. The process involves using trigonometric functions and understanding the impact of currents on navigation.

What is the speed of the boat in nautical miles per hour?

• 30 knots

• 40 knots

• 50 knots

• 60 knots

What is the bearing of the current affecting the boat?

• N 20 degrees West

• W 20 degrees South

• E 20 degrees North

• S 20 degrees East

Why is it important to correct the boat's course?

• To avoid going off-chart

• To increase speed

• To reduce fuel consumption

• To improve navigation skills

How is the angle of the boat's direction represented for calculations?

• Using bearings

• Using standard angle form

• Using degrees only

• Using radians

What is the resultant vector used to determine?

• The boat's capacity

• The boat's weight

• The boat's final speed and direction

• The boat's fuel efficiency

What is the calculated speed of the boat considering the current?

• 50 knots

• 30.79 knots

• 40 knots

• 60 knots

What is the final bearing of the boat's direction?

• South 6 degrees West

• North 6 degrees East

• East 6 degrees South

• West 6 degrees North
