Jim-

I'd recommend The Boater's Bowditch as a good book for you to get on navigation. It is a more readable, re-written and edited version of Bowditch's, designed for the small craft navigator specifically.

The GPS Plotter is a parallel rule, but it moves perpendicular to the long axis, rather than at an angle to it... and it has small holes for a pencil tip to fit into at various locations on it. I have one... the only thing I didn't like was the rubber feet...they came off about a week after I started using mine... and had to be replaced.

Defender.com, landfall navigation, west marine, bluewater books, all sell the navigation tools.

If you do use a mechanical pencil on-board, highly recommend you spray it down with Boeshield T9 to prevent it from corroding and jamming. I use the Pilot Vanishing Point mechanical pencils. They have a lead type indicator collar and an extended fine tip that retracts to protect it from breakage or damage. BTW, I generally use HB lead in the mechanical pencils, as it is a bit harder than 2B, so it doesn't break as readily IMHO.

Where's a good place to get dividers like those?

Any protractor, or something special? (And what, precisely, do you use it for?)

I really gotta make a navigation book choice...

Thanks,
Jim

You know what the first rule of sailing is? ...Love. You can learn all the math in the 'verse, but you take
a boat to the sea you don't love, she'll shake you off just as sure as the turning of the worlds. Love keeps
her going when she oughta fall down, tells you she's hurting 'fore she keens. Makes her a home.
