With variety of styles, shapes and proportions of today’s sailing cruising catamarans, it is important for the designer to consider aerodynamic and functional aspects of catamaran architecture. Different shapes of catamaran cabins representing major trends in the industry were modeled using CFD methods. The modeling included definition of aerodynamic forces and moments and flow visualization at number of apparent wind angles, for each studied version of superstructure. Effect of aerodynamics of superstructure on performance is analyzed by VPP. Practical considerations are discussed in conjunction with results of aerodynamic modeling, covering comfort, appearance, functionality of catamarans. Recommendations on shaping are proposed; design samples showing variations of shapes are featured.
