AN EXPERIMENTAL STUDY OF A HIGH PERFORMANCE TUNNEL HULL CRAFT
Model resistance and self propulsion data are presented from experiments on Model 5048 modified for shallow and deep tunnels and with propellers of two different diameters. Comparisons are made with data previously obtained for the same model without tunnels, and the tunnel configurations are evaluated by means of an efficiency factor. The deep tunnelled hull in combination with propellers of large diameter and the smallest permissible tip clearance compares performancewise to the hull with no tunnels. A format and sufficient dimensionless coefficients are provided for horsepower estimates for alternate hull designs. Because the navigational draft requirements for the tunnel hull are much less than those without tunnels, the tunnel hull is considered to be highly desirable.
