... that forms aft of the step, often reducing the frictional resistance. This paper summarizes model tests that were conducted on a prismatic planing hull, with two adjustable stern sections, to form either a single- or twin-step planing hull. Measurements were made of the resistance, heave, wetted lengths...

... of planing craft. In this article, empirical equations for the pressure distribution on prismatic planing hulls are developed, including both hydrostatic and hydrodynamic effects, deadrise variation, trim, and wetted length. The empirical method is based on relevant experimental measurements of planing hull...

... and the hydrodynamic problem is solved in the time domain. The time-varying wetted-length change due to the water flow is accounted for by a generalized Wagner approach. The present theory is verified by comparison with an analytical solution by Sedov (1940) for water entry of a planing plate and with the linear...

...Armin W. Troesch This paper is concerned with the various modeling assumptions associated with planing boat dynamics and hydrodynamics when the hulls are traveling at low to moderate planing speeds. In particular, experimental results of the time-dependent behavior of the wetted length, amplitude...

...Masatoshi Bessho; Masahiko Komatsu The two-dimensional unsteady problem of a flat planing surface is analyzed based on airfoil theory. The present analysis treats the effect of the time-varying wetted length on the added mass and damping coefficient. When the reduced frequency becomes very small...
