The very best tool is: Blundel-Harling Portland Course Plotter Portland Plotters--also known as Breton Plotters-- are the plotters of choice for commercial navigators. This heavy-duty model features: A moveable compass rose grid. When aligned on chart parallels it automatically sets the drawing edges on the course bearing required. Variations can be pre-set on the moveable rose for easy compass bearing plots. Edges are graduated in inches and centimeters Large numbers make the plotter easy to read under difficult conditions http://www.waypoints.com/plotters.html -----Original Message----- From: NavList@fer3.com [mailto:NavList@fer3.com] On Behalf Of Greg R.

As someone who moved over to marine navigation from the aviation world, the Weems plotter was most familiar to me and easiest to use (though I also had experience with parallel rules from Navy service days). Being someone who likes to experiment (and try new ways of doing things), over the past few years I've managed to accumulate just about every plotting tool in the Celestaire catalog: square protractors, a couple of the Bi-Rola plotters, GPS plotter, 3-arm protractor, protractor triangle, Plotfix, and the Chartkit plotting board (hopefully I didn't forget anything... ;-)), though I don't have any experience with any of the Linex items. And I just ordered the Paralock plotter over the weekend because it claims to make plotting GPS fixes easy. Can't say that I have any particular "favorite" of the lot, it's pretty much a case of whatever tool is the right one for the job du jour. That and the usual assortment of drafting tools (dividers, compass, etc.) pretty much round out that part of the navigation kit - but from a practical standpoint all of that is usually replaced by a laptop computer and Navigator software. :-) -- GregR > I was just wondering what people use to plot their LOP's and lay down > their course lines? > > Here in the US Merchant Marine, we are partial to a pair of > navigational triangles, a compass, and a pair of dividers.
