Blundell Harling Portland Course Plotter Chart Pack

This plotter, based on the original Breton plotter, makes navigating much easier as it can calculate bearings quickly and accurately. It gives courses and tidal information without having to move across a chart by using the rotating compass rose in the centre of the plotter; so is easier to use in cramped and rough conditions.

Features

• Bright blue directional arrow prevents accidental reciprocal bearings.
• Edges are graduated for tide and boat speed.
• Base has a fixed grid so it is easy to plot latitude from your GPS system.
• Comprehensive instructions included.
