On the Water With C-MAP
Charts + Depthsounder= Safer Navigation
“There are two kind of sailors on the St. Lawrence River — those who’ve run aground and those that will.” These prophetic words from avid area sailor Paul Van Voorhees underscore an important aspect of electronic navigation Van Voorhees uses as he explores the St. Lawrence River and Lake Ontario aboard his 28-foot Hinterhoeller Sloop Orion. Van Voorhees speaks from experience — both in terms of the many days he spends each year exploring these waters and the fact that, even with all the care he takes, he’s “found himself aground” before. He uses a Standard Horizon CP-390i and C-MAP MAX Charts, and offers other boaters this “sound advice” for the region.
“The St. Lawrence River was dynamited to create the St. Lawrence Seaway, and as a consequence, there can be a lot of water beneath you… if you’re in the right spot. If you’re not in the right spot, you can get into trouble quickly.” Van Voorhees uses his chart plotter and built-in depth sounder simultaneously to navigate by depth.
By keeping an eye on the spot soundings on the charts, the position of his vessel on the charts and the real time readings of his sounder simultaneously, Van Voorhees is able to verify his location on this sometimes tricky waterway and increase the chances of keeping enough water under his keel. “I’ve found the sounding data in the MAX charts to be quite accurate, and have found the amount of detail and accuracy of surrounding land features to be superior to other charts I’ve used.”
