The use of the Potential Theory to evaluate the Resistance to the Advance of Fishing Ships in waters calms, it is investigated, with the main objective of obtaining comparative results that allow to evaluate the acting of the theoretical method for the use in the process of the preliminary project. The simplicity and speed of the algorithm of the computer provides a valuable tool that can be used to carry out analysis of different types in ways of fine ships, including ships with bulb prow, and to obtain qualitative results at a cost very low. This way the interference of the different parts of the hull can be analyzed and the forms of the ship optimized to obtain a minimum resistance to the advance for formation of waves.

Gran parte de los accidentes con embarcaciones pesqueras se deben a problemas de estabilidad transversal durante la faena de pesca, en la cual la embarcación se escora grandes ángulos, y muchas veces al no lograr recuperarse, zozobra. En los estudios y peritajes llevados a cabo por las Aseguradoras generalmente se llega a la conclusión de que la embarcación superó su límite de estabilidad. Este límite de estabilidad en algunos casos puede no haberse evaluado correctamente. En este trabajo se discute la eficiencia del cálculo de estabilidad estática transversal usado en el diseño de buques y embarcaciones pesqueras de la flota peruana, basados en los diagramas de curvas cruzadas de estabilidad tradicionales. La discusión se basa en la restricción que es impuesta por el método de cálculo tradicional que condiciona el trimado de la embarcación a permanecer inalterado. Los cá...

La utilización de la Teoría Potencial para evaluar la Resistencia al Avance de Buques Pesqueros en aguas calmas, es investigada. con el principal objetivo de obtener resultados comparativos que permitan evaluar el desempeño del método teórico para el uso en el proceso del proyecto preliminar. La simplicidad y rapidez del algoritmo computacional provee una valiosa herramienta que puede ser usada para realizar análisis de diferentes tipos de formas de buques finos, incluyendo buques con proa de bulbo. y obtener resultados cualitativos a un costo computacional muy bajo. De esta forma la interferencia de las diferentes partes del casco puede ser analizada y las formas del buque optimizadas para obtener una mínima resistencia al avance por formación de olas.

A large part of the accidents with fishing boats are due to problems of transversal stability during the fishing task, in which the boat lists at large angles, and many times, failing to recover, capsizes. In the studies and expert reports carried out by the Insurers, the conclusion is generally reached that the vessel exceeded its stability limit. This stability limit in some cases may not have been evaluated correctly. This work discusses the efficiency of the transverse static stability calculation used in the design of ships and fishing vessels of the Peruvian fleet, based on the traditional stability cross curve diagrams that condition the trim of the vessel to remain unchanged. The calculations carried out by the traditional method are compared with others carried out using a free trim calculation method, based on the concept of hydrostatic balance of floating bodies. The calculati...
