El projecte de fi de grau es basa en el disseny amb un programa de dissenys, en aquest cas s'ha escollit Rhinocero 4.0, del veler d'escola el "Barcelona" i el càlcul de les seves corbes hidrostàtiques. El treball es divideix principalment en tres part, la primera es la part més pràctica, i fa referència a la creació del motlle de la maqueta de l'embarcació i el càlcul del desplaçament, amb l'ajuda de l'aplicació dels mètodes aproximats. la segona part s'enfoca en el disseny i els passos que s'han seguit per arribar fins a ell, i finalment el càlcul de les corbes hidrostàtiques mitjançant el programa Maxsurf Modeler i Maxsurf Stability. S'ha de mencionar que aquest projecte parteix del "final", es a dir, tenint l'estructura i no sabent cap característica principal ni cap plànol. In order to create a vessel we need to start by the design. Those who are engaged in the creation of new boats are helped by the so-called spiral design of the ship. This will structure features or steps to be followed to perform and have a good design. Like any other procedure, we have a beginning and an end. The beginning of the design of a naval structure will start from the requirements of the vessel, like its geometry, structure, propulsive system, etc. As the end, to obtain the physical structure and the objective that has been proposed for that vessel. In this case we start from the end, there is a physical structure, and also it is known that the operation is corresponding, but we do not have any plan or drawing where it helps to know the size or shape of the main helmet that the boat has. This work consists on creating the design of the vessel in the chosen program, Rhinoceros 4.0, and calculate hydrostatic curves. It is structured in three main parts; the first is the procedure of how the measures are taken and the calculated values using approximate methods. The second part is focused on the completion of the design step by step, and finally the third part, which calculations Hydrostatic curves are obtained. The main objective is to get a design very similar to the sailboat BARCELONA, as well as the calculation of hydrostatic curves to be the most approximate of how another boat with the same characteristics should be.
