Rhumb-line calculation at 5.5 kn — a line of constant course, the way it is drawn on paper.

What it will do

Chart with a sea layer

OpenSeaMap on top of the map: buoys, lights, cardinal marks, depths. Waypoints go in with a click, order changes by dragging.

Proper units

Miles and knots, three-digit courses, coordinates in degrees and minutes — as on a plotter and in the log book.

Day-by-day breakdown

Mark overnight stops and see the length of each sailing day — and whether you make harbour before dark.

GPX export

The route opens in a plotter, Navionics and OpenCPN. The link can be sent to the crew.
