Method
Click to add waypoints along your intended route. The tool sums each segment and converts metres to nautical miles using 1 nautical mile = 1,852 metres. Estimated travel time equals distance in nautical miles divided by average speed in knots. The waypoint list can be copied in a selected coordinate system.
Example
A route of 14 nautical miles at an average speed of 7 knots takes 2 hours before allowing for stops, current or other delays. Load the Stockholm sample route to compare the same route at different speeds.
