SELF-RIGHTING BOAT DESIGN

Öz

The stability behavior of small craft is of great importance at very high angles of heel, up to the completely inverted condition. The fundamentals of stability in the design of yachts and other small craft is considered, and the significance of our current understanding is reviewed based on static stability analysis. There are three main self-righting methods examined in this study. These are; inherent self-righting method, inflatable bag method and moveable ballast method. All of them have their advantages and disadvantages. Inflatable bag is easy to apply and maintenance, but there are very small area of applicability and does not ensure safety of the crew. Moveable ballast method practically applicable only for small craft and maintenance of mechanical components is hard. On the other hand, it can be designed to be self-operating system and fitted to small open boats where buoyant superstructure is not a feasible option. Although designing inherently self-righting craft is challenging due to the difficulty of weight distribution’s uncertainty during the design process, it is the best option for any self-righting vessel
