When you are cutting up charts, are you being sure to cut large enough to keep at least one Rose on the page, or are you putting a new one on (some marine stores sell compass roses with a sticky back for placing on charts). Also, what about all the Long and Lat markings?" >> I ruled them with lines parallel to magnetic north, separated by about 3 cm, and labeled the edges with major lat/lon marks ... and put a nautical mile somewhere on them along with the distance in mm for the nautical mile. When I made those charts back in 1996/1998, GPS was not in my future (is now), so I was not expecting to use precise waypoints. The parallel lines of mag. north were used with a large Weems/Plath protractor/triangle to pull bearings and ranges off the charts (or put 'em on in camp). The protractor had a millimeter scale for estimating distance from the nauty mile on the chart. Works slick on a rockin' and rollin' deck and with a deck compass about all I ever needed for the kind of navigation I did then. -- Dave Kruger Astoria, OR *************************************************************************** PaddleWise Paddling Mailing List - Any opinions or suggestions expressed here are solely those of the writer(s).
