The invention relates to a device which makes possible towing and transport of a boat without it being necessary to use a trailer during its movements on land. This invention makes it possible to render amphibious a boat designed for this purpose. It is constituted by the incorporation, at the time of moulding of the hull, of a rolling or landing gear, on tyres and shock absorbers, which is retractile as required, as well as a towing bar with a fixing ball, known as a drawbar, which is made of metal and is retractile as required and comprises a small front wheel for the requirements of support on three points. This device makes possible the automatic reconstitution of the stem and of the curve of the boat via a system of closing the housings necessary for the innovative apparatuses. It is intended for better use of a marine vehicle in its civil, sport or military aspects. <IMAGE>
