Web22 Jul 2024 · There are two ways of doing this: add sponsons to the ship’s sides or a sponson-ducktail to the stern. Side-mounted sponsons provide an effective way to improve stability but they also make the ship wider, which can be a problem when entering ports or canals. Sponsons on the side are also visible, which might be undesirable. paul schippert
