Of course here's the issue of going solely by Chartplotter (consider yourself someplace else - perhaps near a reef marked on a chart). Chartplotter maps often don't get updated frequently by most people. The cartography is expensive to maintain. In other words, while you can update your PC/Mac software NOAA ENC and RNC charts for free, it could cost hundreds of dollars to update your charts on your Raymarine or Garmin. This is being worked on however, as a few of the companies are offering lifetime updates, user added content and other features to their chartplotter cartography.

Anyway, here's a pic of innacurate cartography that could lead to some issues with pre-done waypoints on a chartplotter.
