Opis:
The aim of this study was to investigate possible application of fast design prototyping methods for wind-steering systems used in offshore sailing yachts. The development of such methods would help to speed up the construction work and reduce the scope of necessary experimental research, prior to implementation of the system. In the present work, based on an analysis of existing designs of windvane systems, a preliminary selection of the system configuration has been undertaken, in terms of a compromise between efficiency, performance, and design complexity. Construction design of a single- stage, servo – pendulum system, has been developed by using the Autodesk Inventor design package. Next, based on the design data, a simulation model of the system, has been produced by using Matlab – Simulink software and SimMechanics library. The model was further verified in terms of kinematics mapping with the use of Matlab visualization tools.

Opis:
This paper presents the general principles of building a sailing yacht designed for people with multiple disabilities. Specific requirements for the crew on such vessels have been stressed. A lot of attention has been given to the possible disabilities of the design subjects and accessibility of the new yacht. The universal design method has been adopted to enable meeting ergonomic and rehabilitation requirements. We discuss selected stages of the design process: problem analysis, yacht construction and equipment. We discuss the influence of the type of disability on yacht use, in detail. Two tasks have been combined, that of a sailor with disabilities and that of a yacht. Both of them need to be taken into account in the socio-technical ‘sailor with disabilities - yacht’ system. A set of required yacht adaptations has been developed to meet the relationships in this system. Typical dangers in sailing on the Empatia 60 FD yacht are further enumerated. We provide a set of design rules for constructing dedicated yachts for the disabled and their practical use.

Opis:
The paper presents a framework for optimising a sailing yacht rig using Multi-objective Evolutionary Algorithms and for filtering obtained solutions by means of a Multi-criteria Decision Making method. A Bermuda sloop with discontinuous rig is taken under consideration as a model rig configuration. It has been decomposed into its elements and described by a set of control parameters to form a responsive model which can be used for optimisation purposes. Considering the contradictory nature of real optimisation objectives, a multi-objective approach has been chosen to address this issue. Once the optimisation process is over, a Multi-criteria Decision Making method based on a w-dominance relation is applied for filtering out the most interesting solutions from the obtained Pareto set. The proposed method has been implemented, and selected results are provided and discussed.
