We optimize the driving force and driving force to heeling force ratio for the rig of the clipper ship Maltese Falcon in moderate upwind and reaching conditions. We use both a gradient-based cost function minimization and one based on Evolutionary Strategies. Our computational model is a 2D cross section of the three yards half way up the mast. The flow is computed with the Spalart-Allmaras Reynolds-Averaged Navier Stokes solver, which is suitable for the small apparent wind angles in this study. We present optimal sheeting angles for the fixed camber sections in the Maltese Falcon design as well as optimized cambers. The sheeting angle results closely match those of wind tunnel tests of the clipper ship for upwind conditions, and show good agreement in close and broad reaching conditions. The optimized cambers vary from fore to aft mast, and are larger than the camber found optimal for a single sail.
