Abstract
A marine vessel or watercraft may be provided with an aft extension that, in one configuration of the watercraft, alters the wake of the watercraft, for example by reducing the height of the wake, and which may include a sealable opening to provide crew or payload access into or out of the watercraft at a location (e.g., aft of the transom) that may be difficult for an observer to perceive. The aft extension may be positioned above the watercraft's waterline when the watercraft is in another configuration such that it does not contact with the water to reduce adverse impact on performance characteristics, such as drag, of the hull when the watercraft is in that configuration. The watercraft may transition between the two configuration by selectively varying the displacement of the watercraft or by articulating of the aft extension.
