When I did a lot of pencil and charting, I got an articulating plexi straight edge with a compass on it from the BBA. I used two clevis pins which I drop into the pre drilled holes which they used to screw it down to a plotting board for their BBA chartkit. This means I can set the compass / straight edge parallel to the lat lon line and rotate the straight edge to read or plot courses. I don't have to worry about losing two triangles, store them, and walk them to the compass rose on the chart I am using. I clip the chart to my desk top. My desk now has two small holes drilled in the upper left corner where the clevis pins live when the charing device is stowed.

This system is essentially fixed to the desk (though I can lift it off and stow it) which makes it very useful in a sea way. I never use my triangles or a rolling straight edge.
