I've been wondering about what tools I'll need at the nav station. Two I can think of right off: A pair of dividers and either a parallel rule (I think it's called?) or a pair of triangles. Those two will allow me to determine distance and bearing, correct? Watching a Garmin instructional video, there's a guy using a clear plastic, rectangular thing with a half-circle in the middle and all kinds of graduations all over. What's that? Looks like something else I should probably have? (And learn how to use
) Anything else, besides soft lead pencils (what hardness works best?), sharpener and erasers? And charts, of course
If I choose to use a mechanical pencil, what thickness works best?
(This is just the Great Lakes I'll be navigating, so I think I can forgo the expense and learning curve of a sextant and celestial navigation for the nonce.)
