The invention relates to a floating lifting device enabling a boat to be lifted up, especially with a view to carrying out work to repair or overhaul its hull out of the water and therefore under optimum working conditions. It is characterised in that the structure for linking the floats 4 consists of a framework 16 fixed under the floats and which, seen in front view, has a general shape in the form of a U so as: - on the one hand, to go around the central volume 17 necessary for the passage of the platform 3 and, - on the other hand, to contribute to the lowering of the centre of gravity G. <IMAGE>
