Did you know that your vessel could be dropping and weighing the wrong anchor? Or perhaps you are still using the anchor your boat came with thinking that these boat components are all alike. In fact, there are two considerations when purchasing boat anchors. One is, of course, what type and/or size vessel you have. The other reason that is most often overlooked is the bottom conditions of the waters they will be traversing.
Waterways with rock or coral or shale, clay and grassy, or sandy, muddy, bottoms require different kinds of anchors. And if you pilot your vessel through salt, fresh and brackish waters you will need different types of marine anchors for each of these conditions.
To prevent drift, anchors must tether a boat properly. Anchors must develop sufficient resistance in the seabed to offset wind and waves around the boat. The seabed has to be penetrated by the anchor to hold the boat in place. Below are some anchor recommendations based on differing seabed conditions.
There are several other considerations when determining which anchor(s) are best for your boat, including its type, size and the composition of the anchor. The tensile strength of galvanized steel makes it the most popular anchor choice. Stainless steel is also good as its appearance enhances the bow when not in use. Ultralights and racing sailboat owners are weight conscious and prefer anchors with a lightweight aluminum alloy. As you might expect, anchors made of heavy cast iron really dig into the sea bed to hold strongly.
