Consumer’s Edge: Practical Sailor Takes a Look at Updating Digital Charts

Compare the cost and process of updating e-charts from Jeppesen Marine (C-Map), Garmin, and Navionics.

The world beneath the waterís surface is an ever-changing one, and to keep out of harmís way, a navigator must have the most up-to-date charts available.
