Coefficient characteristics of mid-section coefficient
The larger ratio of the mid-section coefficient is beneficial to increase the loading capacity and reduce the draught, but if the ratio is too large, the resistance will increase. The better shape of the wooden sailboat, the coefficient of mid-cross section is 0.8 ~ 0.88. The profile factor of the arc-dipper type is larger, and it is beneficial to reduce the resistance, the profile factor of the corner type is second, the trapezoid profile factor is smaller, and it is detrimental to stability. In ship design, the prism coefficient of the ship is often adjusted by changing the coefficient of the mid-section to control the distribution of the ship's drainage volume along the length of the ship.
