After the ship is launched into the water and the completion of the welding works on the hull formation (installation of superstructures, masts, etc.) is measured at one load of the ship, the inclinations of the test sites and relative to the central control site, corresponding to the elastic line 4. Based on the measurements obtained, t the equation of the angles of rotation of sections of an equivalent bar of the hull of the vessel at this load, using the method of least
