Socials 8-3/8-1: Explorers and their ships

Today, I explained the way an airplane wing achieves lift and how a lateen sail can be thought of as a wing on its end.  In this way, a sail can be pulled by the wind as well as pushed by it.  This knowledge is key to understanding how advances in sailing technology allowed navigators to move more easily between places on Earth.

Please ensure you have the Ships and Navigation study guide done for homework.
