2. Chart Plotter Navigation Enhancement Tools
C-Map’s PC-Planner ($180, jeppesen.com/lightmarine) lets users of its Max and NT+ chart cards duplicate chart viewing and trip planning on their home computers. You can plan routes and fishing trips and transfer your valuable waypoint collection to a home PC as backup insurance. Navionics (navionics.com) has a downloadable app that can provide you with much the same features.
