Trip Planner Using Currents to Estimate Transit Times

How Current Can Affect Your Trip

It is easy to understand the effects of a current that is either directly with or against your direction of travel. If you are sailing at 5 knots with 1 knot of current with you, your speed over the ground (SOG), also known as velocity made good, is actually 6 knots. Conversely, if the 1-knot current is directly against you, your SOG decreases to 4 knots. In either case, your boat's knotmeter may show 5 knots (through the water), but your GPS will show the speed over the ground.
