This paper examines planform and aspect ratio effects on potential power of a number of rigs - Bermudan, Lateen, Sprit, Gunter, Dipping Lug and Crab Claw rigs, some with modifications (Figure 1). Coefficients of effective driving force, based on wind tunnel testing, are established for those rigs for a range of courses from close hauled to running. A comparative assessment of aerodynamic merits and demerits of various rigs is made. Also an attempt is made to find correlation between the potential power of the rigs in question, and the speed performance of a given hull driven by these different rigs.
