The invention relates to a 'rotating floating body boat', in particular to a displacement surface novel ship, belonging to the field of shipbuilding industry. The rotating floating body boat is formed by rotating floating bodies, a boat platform, boat side plates, a bow sealing plate and a stern sealing plate, and a power and propulsion device. The rotating floating bodies which do not sink, have buoyancy and rotate at high speed form the rotating floating body boat of any size with a single row, two rows, three rows and more rows of rotating floating bodies. The firm and integral boat platform is supported by rotating floating body shafts, bearings and bearing seats. The boat platform is higher than water surface. When the rotating floating body boat sails at high speed, waves are not generated and the wave making resistance is eliminated, the water friction resistance is greatly reduced, the boat speed is greatly improved, the goals of energy saving and emission reduction are reached, the boat does not sink and the safety is high, the boat can substitute for all kinds of ships in the prior art, and the boat is a novel product for ship update.
