The present invention provides, with reference to Figure 1, an amphibian operable in land and marine modes comprising a hull, at least one discontinuity provided in the hull, and at least one retractable wheel or track drive assembly at least partially located in the at least one discontinuity. A wheel or track drive of the at least one retractable wheel or track drive assembly is retracted above the lowest point of the hull when operating in marine mode, and at least part of the wheel or track drive is protracted below the lowest point of the hull when operating in land mode. The hull is a planing V hull, and the hull has a forward bow section defining a frontal bow surface/area across a beam of the hull. The at least one discontinuity is provided in the forward bow section of the hull, and at least a portion of the wheel or track drive of the at least one retractable wheel or track drive assembly is located ahead of and in front of at least a portion of the frontal bow surface/area when protracted. |
