Actually, it's the length of a minute of longitude that changes according to distance from the equator. Use minutes of latitude (on the vertical or north-south side of the chart) to measure distances on a chart. Chuck Holst -----Original Message----- From: Sid Taylor [SMTP:tayls_at_snowcrest.net] On a chart you can use longitude (not latitude, except equator) to measure nautical miles (nm). A minute is a nm. Just use some dividers to walk-off distances. Hell, use a piece of paper with tick marks. How precise do you need to be? I often use fingers or any handy object. Those roller type devices are ok when you're sitting at a desk. Do your float plan and use it for reference. *************************************************************************** PaddleWise Paddling Mailing List - Any opinions or suggestions expressed here are solely those of the writer(s).
