A high speed 30-ton patrol boat is provided to increase traveling speed by minimizing wave resistance and friction resistance, to improve stability by keeping buoyancy in cruising at high speed, and to cut down manufacturing cost by forming a chine line of a hull horizontally. Length between perpendiculars of a high speed 30-ton patrol boat is 20 ± 1 M, and breadth of the high speed 30-ton patrol boat is 4.6 ± 0.1 M. Height of the 30-ton patrol boat is 2.1 ± 0.1 M. The designed load draft is 0.8 ± 0.1 M, and the maximum output of two main engines of the patrol boat is 1000 horsepower. RPM(Revolution per minute) of each engine is 2300 rpm. The 30-ton patrol boat made of synthetic resin sails along the coast for patrolling, and vertical height of the center of gravity is 1.647 M. The center of buoyancy is positioned at 1.189 M in a rear part of a center of the body of the patrol boat. The center of gravity is -2.436 M in the rear part of the center of the body. A chine line is arranged in a line with a water line by equalizing an inner side line to an outer side line.
