SHALLOW WATER AND CHANNEL EFFECTS ON SHIP WAVE RESISTANCE AT HIGH SUB-CRITICAL AND SUPER-CRITICAL SPEEDS

Calculations using existing linearised wave theory, which was used in previous work to predict the effect of shallow water on ship resistance at high sub-critical and super-critical speeds, have been extended to include the effect of restricted channel width with the ship represented by a simplified hull with parabolic waterlines and rectangular cross-sections as before. The calculations have been compared with a small amount of data available for resistance measurements on a relatively large planing hull in a water channel. It has been found that the correction applied to the experimental data using the restricted channel theory improves the agreement between the data and other measurements in effectively unrestricted water.
