C-Map Marina Basin detail.

Posted on May 10th, 2016

We all know water temperature can be critical when it comes to locating feeding fish, especially in the spring when most water temps are cold. During these “cold-water” periods finding an area of shallower, protected water can mean a few degrees higher temperature and of course, active fish.

I often look for marina basins that are not open in the early spring so there is little boat traffic. With the With the C-MAP 4D charts I have in my Raymarine fishfinder not only does it show me the marina basins, but it also gives me the exact location of docks as well as bottom contour lines. I always use this information in conjunction with my fishfinder and DownVision to mark key fish holding areas & fish at the same time.


If you are looking to upgrade your charts on your present fishfinder, or you are planning on getting a new one, you should really consider C-Map charts, they will meet all of your fishing & boating chart needs.
