<P> A small draft allows pleasure boats to navigate through shallower water . This makes it possible for these boats to access smaller ports, to travel along rivers and even to' beach' the boat . </P> <P> A large draft ensures a good level of stability in strong wind, as the center of gravity is lower (ballast over the keel of the boat). For example: Ballasts placed very low in the keel of a boat such as a dragon boat with a draft of 1.20 m for a length of 8.90 m . </P> <P> A boat like a catamaran can mitigate the problem by retrieving good stability in a small draft, but the width of the boat increases . </P> <P> For submarines, which can submerge to different depths at sea, a term called keel depth is used, specifying the current distance from the water surface to the bottom of the submarine's keel . It is used in navigation to avoid underwater obstacles and hitting the ocean floor, and as a standard point on the submarine for depth measurements . </P>
