A movable platform unit ( 1 ) for a boat (B), in particular for launching or hauling out a tender or the like, includes a base portion ( 2 ) secured to the boat (B) and at least one swing arm ( 32 a, 32 b), pivoted at one end onto the base portion ( 2 ) and at the other to a load platform ( 3 ). The swing arm ( 32 a, 32 b) can be rotated by a first drive member ( 57 ) secured thereto and rotatable about the axis (x) about which the swing arm ( 32 a, 32 b) is pivoted on the base portion ( 2 ). Alignment means ( 67, 68 ) are provided for connecting the load platform ( 3 ) to a second drive member ( 65 a) secured to the base portion ( 2 ) and coaxial with the axis (x) about which the swing arm ( 32 a, 32 b) is pivoted on the base portion ( 2 ) so as to enable the platform ( 3 ) to maintain a constant inclination to the base portion ( 2 ) during rotation of the swing arms ( 32 a, 32 b) |
