El presente artículo describe un código computacional, desarrollado para la elaboración de mallas regulares de cascos utilizando cuvas B-Splines cúbicas. El procedimiento de mallado comienza con la definición de curvas B-Spline, en el sentido transversal del casco, sobre las estaciones y los contornos de la proa y popa de un plano de líneas de forma. Por medio de estas curvas B-Spline es posible la creación de nuevos puntos igualmente espaciados en las regiones donde fueron definidas. Posteriormente, con estos puntos son trazadas curvas B-Spline cúbicas en el sentido longitudinal del casco, las cuales son utilizadas para obtener puntos igualmente espaciados, que permiten la creación de nuevas estaciones. Finalmente, los puntos transversales y longitudinales son utilizados para formar los paneles cuadrilaterales de la malla del casco. Este procedimiento es aplicado en los cascos sumergidos del modelo de casco Wigley y Serie 60 Cb=0.60. Los volumenes de estas mallas son calculados usando el teorema de la divergencia para servir como parametro de control de la calidad de la malla.
