The stern deck is the rear part of a ship or boat, typically where various activities take place. It often serves as a space for passengers to relax, enjoy views, or engage in recreational activities. The design and layout can vary depending on the type of vessel, such as a yacht or a fishing boat. On larger vessels, the stern deck may also include features like seating areas, fishing equipment, or access to the engine room. It plays a crucial role in the overall functionality and enjoyment of the vessel, providing a designated area for socializing and leisure.
