In this paper we describe the application of the precorrected-FFT accelerated boundary- element method to linear, frequency-domain and nonlinear time-domain seakeeping analyses for a compete MOB. Acceleration reduces the computational run-time an memory cost for these boundary-element methods from order O(N2) to order O(N log N), where N represents the number of computational elements. In the MOB examples considered, exploiting accelerated methods reduced CPU time by nearly two orders of magnitude and memory by nearly an order of magnitude.
