Provided is a locking apparatus for a damping device of a moonpool, which can automatically lock and unlock an opened state of the damping device of the moonpool. The locking apparatus includes: one or more first locking members installed in a sidewall of the moonpool; one or more second locking members installed in a side of the damping device; and a holding unit separably holding the first locking members and the second locking members when the damping devices are in the opened state.

A boat, having a transom, includes one or more aft-facing seats. Each aft-facing seat is positioned proximate to the transom and includes a seat bottom that is inclined at a downward angle in a direction extending from aft to fore, a seatback, a headrest, a seat support structure having at least one hidden compartment therein, and at least one pivot mechanism attached to the seatback and the headrest and configured to allow the seatback to move between a first position in which the seatback is capable of supporting the back of a person seated in the seat and a second position in which the seatback is pivoted upwardly to allow access to the compartment and the headrest to move between an upright position and a folded position. A plurality of handles may be provided for each aft-facing seat, with one at an outboard side and another at an inboard side.

A boat includes a hull having a bow and a transom, a seat support structure, and an aft-facing seat positioned proximate to the transom and at least partially supported by the seat support structure. The aft-facing seat is positioned proximate to the transom and is at least partially supported by the seat support structure. The aft-facing seat includes a seat bottom configured to slide between an inward position and an outward position. When the seat bottom is in the outward position, the seat bottom is aft of its position in the inward position.

A boat includes one or more seats, which may be aft-facing. The seat includes a seat bottom, which may include an aft segment and a forward segment. The forward segment is inclined at a downward angle that extends in a direction from aft to fore such that an aft portion of the forward segment is higher than the forward portion of the forward segment. The seat also may include a leg rest. The leg rest may extend from the seat bottom and be supported at the upper portion of the leg rest with a gap between a lower end of the leg rest and a surface beneath the leg rest such that the leg rest is not supported by the surface underneath the leg rest.
