    Another vote for the Jean Cras plotter. I have had two on my boat for years and like their flexibility and the fact that there are no moving parts, unlike the Breton plotters, popular with many UK yachtsmen.

    They are now available with coloured scales, which I suppose makes them slightly more convenient to use.

    In my career as a maritime pilot I saw no other type of plotter on the bridges of French ships, but not once in ships of other nationalities.

    I don't consider traditional parallel rules easy to use on a sailboat chart table, bouncing around at an angle of heel. However, the new Weems and Plath Paralock plotter, which is quite small and allows the parallel rules to be locked open is also now in my growing collection of chart table tools.
