When heading out on a road trip, all you need is a full tank of gas and a map. But, a map isn’t going to help you at sea. When planning an ocean voyage, explorers need a different set of tools. Charts, dividers, a compass rose and a ruler are their guides. With information about latitude and longitude, ocean depth and even “knots” these tools can help sailors plan their course and arrive at their destination, without a single road sign! Create your own voyage by looking at charts and try your hand at setting a course!
