The shivering cold of a dimly lit boat shed is a challenging environment in which to take accurate measurements and difficulties are compounded by the contortions necessary to reach the work.

*If the distance between two points is longer than the spread of your dividers, spread them along the edge of the chart in a workable number of miles (or minutes of latitude).
Determine the distance of each course in nautical miles using your dividers and the distance scale on the top or bottom of the chart. This is done by putting one end of the dividers on your start point, and the other end at your stop point or turn.
The usual navigation tools: Charts, dividers, parallel rules, pencils, hand held compass, binoculars. All this is usually aboard every charter boat, but I am used to bring my own in my sail bag, because I know I can rely on my own equipment.
To measure the distance between two places on the chart spread out the dividers till their points are over them, then apply to the graduated scale at the bottom of the chart, which will give you the required distance.
To measure the distance of your planned track, place your dividers on the vertical scale of the chart and measure the distance of one nautical mile by measuring the distance of one minute. Now walk you dividers down the track and measure its distance.

Navigation equipment can be simple. Charts, including a reasonable area around your intended route, tide table, dividers and parallel rule, sighting compass and, of course, the trusty GPS. A good pair of binoculars can help.
A person using the map can use a pair of dividers (or, less precisely, two fingers) to measure a distance by comparing it to the linear scale.
assure me that nav stations in small boats were passé because instruments are better positioned at the helm. I disagree. I like to be out of the elements and away from the crowd. I can sit below and putz around with charts, plotters and dividers.
