1. What is the distance from A to B ?_______________

2. How long is each tack?_____________

3. How many tacks are needed to get from A to B?______________

4. What is the total distance traveled from A to B (multiply tack length by number of tacks)?________________

5. What is the difference between the actual distance from A to B and the distance traveled?______________________

   This is the extra distance a sailing ship has to travel to use the wind as it's "engine" when the wind is coming from the direction it wants to go.

Part III: Winds and Currents Worksheet

ACTIVITY 3

If you threw a bottle into the ocean from Ocean City, Maryland, where do you think it would land? Mark an "A" on your currents map to show where you think it would land. If you know the name of that location, write it here. What would affect its course: winds, currents, or both?

If you threw a bottle into the ocean from Los Angeles, California, where do you think it would land? Mark a "B" on your currents map to show where you think it would land. If you know the name of that location, write it here.

If you threw a bottle into the ocean from Ocean City, Maryland that had a sail on it, would that change its destination? If you think the destination would change, mark a "C" on your currents map to show where you think it would now land. If you know the name of that location, write it here. If you do not think the destination would change, write that here. What would affect its course: winds, currents, or both?
