Chartplotter Protocols

by Steve Henkind, Posted November 20, 2008
Chartplotters are powerful extensions of GPS technology and provide tremendous convenience, but they can get you into trouble if you’re not careful. While my focus is on vector-based plotters (digitized charts, which are the ones typically found on recreational sailboats), most of my observations also apply to raster-based (scanned charts) plotters.Scale change matters.

GPS has greatly simplified certain aspects of navigation; at the mere touch of a button, a boat’s position can be determined within about 30 feet.

He is nowhere to be
