If you’ve ever looked out to the Strait of Juan de Fuca and wondered what that big boat in the distance is you can pretty easily figure it out by going to VesselFinder. The free service provides not only information on boats (big ones, mind you, not little ones) but also ports and boating news. iOS and Android apps are also available. VesselFinder is the water equivalent of FlightRadar.
