Navigating Casco Bay
Casco Bay, ME is a coastal waterway in Maine, and this page collects what Navi Wake knows about navigating it. The waterway is charted for routing, which means Navi Wake can plan a path across open water that stays off the land and follows the channel instead of drawing a straight line through a peninsula.
We hold 975 charted navigation aids on Casco Bay. That breaks down into 205 channel markers, 631 marked hazards, 109 lights, and 30 special-purpose markers. We also chart 41 public boat ramps and 44 marinas on the shoreline, mapped separately from the aids above. Depth coverage comes from 6,153 surveyed soundings and 1,912 depth contours, which is what lets the chart shade the shallows.
