USE OF LAGRANGIAN COORDINATES FOR SHIP WAVE RESISTANCE (FIRST- AND SECOND-ORDER THIN-SHIP THEORY)

The wave motion generated by the steady motion of a ship is formulated exactly in Lagrangian coordinates. An approximation scheme is then developed based upon a method of iteration. The first iteration can be chosen so as to yield the Michell thin-ship theory. The second iteration produces more complicated formulas. However, if the smallness of draft/length is taken into account, the formula for the resistance simplifies to one similar to Michells, but with the integral taken over a modified region and with a modified hull function, plus a line integral over the profile which represents a distribution of dipoles with strength proportional to the waterline slopes.
