46m Ketch Balance Study

Balance study for shallow draft 110' Ketch

Mega yachts often have helm balance problems for a number of reasons.  One of the major reasons is they are limited in draft due to depth restrictions.  We used our RANS based VPP to model this 46m ketch sailing upwind to evaluate helm balance during the design cycle.  The two major designs questions of the study were are the masts in the proper location and is the rudder big enough to balance the boat and maintain control lin all conditions.  The images shown in the slide show are CFD post processing images from the study.
