In the previous report, numerical analyses of free surface flow around a sailing yacht were carried out in upright condition with and without leeway by means of PAFS (Panel method Applied to Free Surface flow) inluding rudder effects. In those results, it was concluded that the free surface flow around the sailing yacht with leeway can be simulated well by PAFS. In the present report, some results of numerical analyses for KIT-34 are given under the condition with heel. Hydrodynamic interactions between the main hull, the fin keel and the rudder are also studied, in which the calculated results of hydrodynamic forces acting on the fin keel or the rudder on the assumption that these appendages are advancing under the free surface independently are compared with the calculated results for these appendages attached to the main hull.
