A system is proposed for putting boats on hold when they are afloat on a water body after they have been launched and/or before they are hauled out of the water. The system for putting on hold includes: a floating device, having a central floating element and secondary elements extending from the central floating element. Each secondary element being associated with a reception place and having at least one point for driving, by thrust or traction, a boat positioned in an associated reception place. A system for moving is adapted to moving the secondary elements around the central floating element and, via the points for driving, moving the boats that are positioned in the reception places.
