Keel jump

from Wikipedia, the free encyclopedia

The curvature of the keel line is called the keel jump in boats .

In addition to the shape of the keel line (V-bottom or keel bar), the keel jump has a decisive influence on the directional stability and maneuverability of the boat: a small keel jump results in greater directional stability at the expense of maneuverability. Pure touring canoes such as B. Sea kayaks often have no keel, whitewater canoes have a very strong keel.

The keel jump is difficult to measure. In the case of a canoe lying flat on firm ground, the measurement would be the distance that the end of the keel line has from the ground. Since the end of the keel line or its transition into the bow is often undefined, no dimensional information is given. The information on the keel jump is therefore comparatively subjective.
