Full Displacement

Full displacement designs are known to move through the water, rather than on top of it, and are considered very seaworthy. Their deep and wide hull shape allows for large fuel and water tankage, large storage volume, and typically have large engine rooms in the center of the boat, as well as comfortable living areas. Single diesel engine models typically have an extended center keel, which can be cutaway aft to protect the rudder and prop, or a truncated keel to provide a certain amount of protection for those powered by twin diesel engines. Hull sections are rounded, making them prone to rolling in a seaway, so many owners opt for some kind of stabilization system.
