Modes

• Static: Steer the boat to a stationary island.
• Dynamic: Direct the boat to intercept a moving school of fish.
• Game: Combines both static and dynamic challenges in a game setting. Earn points for reaching the destination.

Settings

• The magnitude and direction of the boat's speed (blue vector) is always active. It can be adjusted by dragging either end of the vector or by entering different numbers in the boxes along the right panel.
• The magnitude and direction of the current of the water (red vector) can be toggled on and off. When on, it can be adjusted by dragging either end of the vector or by entering different numbers in the boxes along the right panel.
• The result arrow (green vector) can be toggled on and off. It cannot be adjusted directly; it only represents the sum of the other two vectors.
• The Start button allows the boat to depart from its current location.
• The Reset button returns the boat to its original position.
• The New Game button changes the initial location of the island (Static mode) or the fish (Dynamic mode).

In Static mode, try to do three things:

• Direct the boat to the island in just one shot with the red vector (water) turned off.
• Direct the boat to the island in just one shot with the red vector (water) turned on. To do this, it may be helpful to turn on the result vector. How does the result vector relate to the boat and water vectors?
• Set the magnitude and direction for both the boat and water vectors so the boat remains stationary. To accomplish this, what is the relationship between the boat and water vectors?
