Marine vessel with aft extension

A variable displacement marine vessel comprising:

• a hull defining a hull cavity, the hull comprising a transom;
• a weather deck enclosing at least a portion of the hull cavity;
• a rear deck coupled to the hull and extending aft of the transom, the rear deck narrowing in a direction aft of the transom;
• an aft enclosure that substantially encloses the rear deck and forms part of a superstructure of the vessel, the aft enclosure being sized to accommodate a passage of a person therethrough, wherein a bottom surface of the aft enclosure encloses an underside of the rear deck;
• and
• a ballast system that selectively varies an amount of ballast within the hull cavity to vary a displacement of the hull between a first displacement configuration associated with a first waterline located below the bottom surface of the aft enclosure and a second displacement configuration associated with a second waterline located at or above the bottom surface of the aft enclosure.

A watercraft comprising:

• a hull extending from a bow to a stern of the watercraft, wherein the stern comprises a transom;
• and
• an aft extension coupled to the hull to extend aft of the transom, wherein the aft extension has a bottom side offset vertically from a keel of the watercraft such that the bottom side is located above a waterline of the watercraft when the watercraft is operated in a waterway in a first configuration whereby a wake is formed by the hull, and wherein the bottom side is located at or below the waterline when the watercraft is operated in a second configuration such that the aft extension reduces the wake when the watercraft is operated in the second configuration;
• wherein the aft extension is movably coupled to the hull whereby the aft extension is movable between a first position when the watercraft is in the first configuration and a second position when the watercraft is in the second configuration;
• wherein the aft extension is pivotable to reposition the aft extension between the first and second positions;
• and
• wherein the first position is a stowed position in which the aft extension is positioned substantially forward of the transom and the second position is a deployed position in which the aft extension is positioned to extend substantially aft of the transom, and wherein the aft extension is pivotable about a substantially transverse axis to move the aft extension between the deployed and stowed positions.
