A buoyant boat with a girder box is provided. The girder box maintains the deck part and hull part of the boat in predetermined spaced apart relation and allows the transmission of forces and stresses along the length of the boat. The girder box further enables an outboard engine or an inboard engine in the form of a propeller or hydrojet to be provided. A relatively resilient buoyancy part is provided in accordance with the structure of the invention which extends peripherally of the hull and deck parts to advantageously prevent entry of water into the boat while providing the advantages of design variability, stability and puncture resistance over inflatable structures.
