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.

Described is a multi-use offshore structure having a first configuration and a second configuration. The first configuration includes a pontoon base disposed at a lower end of the multi-use offshore structure. A deck is disposed at an upper end of the multi-use offshore structure, and hull column structures extend between the pontoon base and the deck. The second configuration includes the pontoon base, the deck, and the hull column structures of the first configuration. A set of sponsons is formed to be installed on the hull column structures, and a deck expansion unit is connectable with the deck.
