Portland Course Plotter

An advance on all current designs utilising practical user experience and manufacturing technology. The Plotter is precision moulded using water clear high impact acrylic material. A comprehensive instruction leaflet covers all possible uses. A day glow green directional arrow prevents accidental reciprocal bearings and the edges are graduated for tide and boat speed. In addition to normal traditional navigation requirements the Course Plotter is ideal for constructing instant tidal vectors using the Tidal 2000 System. The base has a fixed grid so the Course Plotter can be used to plot easily lat/longs from a Decca or GPS system.
