A submersible raft is disclosed for the cultivation of plant life such as seagrasses or the like. The submersible raft includes a first and a second longitudinal member of tubular configuration. The first and the second longitudinal members each have a first and a second end. A first transverse member extends between the first ends of the first and the second longitudinal members and a second transverse member extends between the second ends of the first and the second longitudinal members. The first and second longitudinal members and the first and second transverse members define a rectangular aperture therebetween. Tray supporting cradles extend between and are supported by the first and the second longitudinal members, the trays being supported below the rectangular aperture such that in use of the raft, pots of plant life to be cultivated are supported below the surface of the water in which the raft is submersed.

A submersible raft for the cultivation of plant life comprising in combination: a first longitudinal member of tubular configuration; a second longitudinal member of tubular configuration; said first longitudinal member including a first and a second end; said second longitudinal member including a first and a second end; a first transverse member extending between said first ends of said first and said second longitudinal members; a second transverse member extending between said second ends of said first and said second longitudinal members; said first and said second longitudinal members and said first and said second transverse members defining a substantially rectangular aperture therebetween, said first and said second longitudinal members being of plastics material; a cradle extending between and supported by said first and said second longitudinal members, said cradle including an upper and a lower framework, said upper and said lower frameworks being of H-shaped configuration and of substantially the same proportions as each other; upright members extending between corresponding free ends of said H-shaped frameworks; extensions of said upright members extending upwardly from said upper frameworks; a loop shaped member connected to each of said extensions, said loop shaped member encircling one of said longitudinal members such that said loop shaped member and said cradle are moveable longitudinally relative to said rectangular aperture; and a tray supported by said cradle, said tray being supported below said rectangular aperture, said tray being supported between said upper and said lower frameworks which define therebetween an opening for the reception of said tray.
