TinyOceanNavigator3 OceanNavigator is a great program for navigating across oceans (and anywhere else, for that matter). Use it to compute way-points, great circle routes, distances, positions, and other useful parameters, as the folks at Black Diamond Sound Systems did aboard the 40 foot yacht Marishanna in the recent Pacific Cup Race from San Francisco to Hawaii.

The program simplifies the process of calculating a number of quantities that are of special

interest to the typical mariner when he or she is at sea. These include such questions as "Where am I?", "Which way should I steer to get to where I want to go?", "How far away is my destination?", "How can I generate Way Points with a minimum of bother?", "How far away is that rock?", and "Will that approaching vessel collide with me?"
