What is a Keel?
Keels are found on most watercraft whether powered by wind or motor. A keel is commonly understood to be a fixed underwater extension protruding from the bottom of a boat although some versions are movable. Keels provide stability and resist sideways movement or drift. Sideways movements are caused by wind or cross currents and are not only countered by the shape and draft (depth) of a keel structure, but also by its weight (or ballast). Movable keels are typically only associated with sailing vessels. Most movable keels move with regard to their being positioned in or out of the water, though canting keels refer to movement that occurs underwater while the keel is already in place. In these instances, the keel swings or angles more severely whenever the watercraft heels (tips) to extreme angles. The adjustment in the angle of the keel will reposition the center point of the keel’s weight and allow for more advantageous hydrodynamics in service to speed through the water. One drawback
