The invention relates to a resistance reduction and energy conservation friendly type ship tail line type, a ship and a manufacturing method. In the resistance reduction and energy conservation friendly type ship tail line type, a corner formed at a junction of a stern transom plate of a hull and a tail lower plate of the hull is a circular angle; and the ship is provided with the resistance reduction and energy conservation friendly type ship tail line type. The manufacturing method comprises the step that rounding is carried out, specifically, rounding processing is carried out on the junction of the stern transom plate of the hull and the tail lower plate of the hull. According to the resistance reduction and energy conservation friendly type ship tail line type, the ship and the manufacturing method, pressure intensity distribution of the tail hull can be changed, a hull attitude is adjusted, and hull wave making is improved, so that the formation of tail vortex during sailing is reduced, and hull resistance is reduced; in addition, flow guiding is carried out when the ship sails backwards, and thus, the sailing backward resistance is reduced; in addition, wave flapping of theship tail during sailing can be reduced to reduce wave increased resistance; in addition, vortexes at the stern transom plate can be reduced, so that vibration and noise of the hull are reduced; and after testing, the total resistance of the hull can be reduced by 1-3%.
