In addition, the seat back may be placed in a stowed position in which the seat back is absent from both the bow-facing and stern-facing seats, such that the seats cooperate to provide a planar support surface along an aft-to-fore extent of the seat assembly. The seat back may be adjustable by hand without tools, such that a user may easily reconfigure the seat assembly to sit facing the bow, to sit facing the stern, or to lie down. ## Claims ### Claim 1 A seat assembly for a boat, the seat assembly comprising: an aft seat;

a fore seat, one of the fore seat and the aft seat are pivotable from an initial position into a raised position; and a seat back pivotable between a first seating orientation and a second seating orientation, the seat back also pivotable into a stowed position beneath the one of the fore seat and the aft seat when in the raised position, such that the seat back is beneath a seating surface of the one of the fore seat and the aft seat when returned to the initial position. ### Claim 15 (depends on 14) The seat assembly of claim 14, wherein, the first seating orientation is a stern-facing seating orientation, and the second seating orientation is a bow-facing seating orientation. ### Claim 16 (depends on 15) The seat assembly of claim 15, wherein: the seat back in the stern-facing seating orientation has a stern-facing surface defining an obtuse angle with an upper surface of the aft seat, and the seat back in the bow-facing seating orientation has a bow-facing surface defining an obtuse angle with an upper surface of the fore seat. ### Claim 17 A pontoon boat comprising: at least two pontoons; a deck having a seat assembly fixed thereto; a motor; controls operable to control the motor and steer the pontoon boat; and the seat assembly comprising: an aft seat; a fore seat; and a seat back pivotable between a first seating orientation and a second seating orientation, the seat back further adjustable into a pillow orientation from one of the first orientation and the second orientation, wherein: one of the aft seat and the fore seat defines a first seat depth from a leading edge of the respective seat to the seat back to provide a couch-type seating arrangement allowing a user's back to contact the seat back and the user's feet to contact the deck of the pontoon boat, and the other of the aft seat and the fore seat defines a second seat depth from a leading edge of the other respective seat to the seat back to provide a recliner-type seating arrangement allowing a user's back to contact the seat back and at least a majority of the user's legs to be supported by the aft seat or fore seat, the second seat depth being greater than the first seat depth. ### Claim 18 (depends on 17) The pontoon boat of claim 17, further comprising: a single-occupancy seat fixed to the deck adjacent the controls;
