| In the last two decades, the Finite Element Method has been growing as a powerful tool for the structural analysis of the ship hull, but in nautical construction the use of this method has been related mainly to steel or aluminium hulls. In a metallic structure the material is homogeneous and isotropic and the plate, or the stiffened plate, behaves as an orthotropic plate, which means orthogonally anisotropic with three mutually perpendicular planes of symmetry; on the contrary, when considering a composite hull panel the scheme ought to be different, because there arise two different problems, which ensue from the structural characteristics of the composite sandwich panel. Firstly, the Element Stiffness Matrix must take into account the natural anisotropy... |

| The mast-rigging combination of a yacht is the structural element which transmits the aerodynamic forces on the sails to the yacht's structure. This load transmission element is in general made up of a mast, a long, thin tube, and the rigging which is a collection of cables linking the mast to the deck. These elements are long, often longer than the hull, with a high centre of gravity and it is essential to obtain as low a mass as possible, both for safety and performance. This search for weight gain imposes the use of lighter and lighter materials: wood, then aluminium alloys and most recently, since the early 1980's, composite materials. The use of the latter is the subject of this paper. |

| The experimental sailing boat "Mesure Z," has been designed and built on behalf of F.I.N., (the French marine industry association). This research project has been managed in close collaboration with Bureau Veritas, Ifremer and the CEA. The GRP hull is similar to that of a production sailing boat, but it has been designed as a transducer-hull, i.e. a hull sufficiently sensitive to allow measurements (hull strains, acceleration, spar loads, etc), due to its structure and mechanical characteristics. This paper presents different aspects of the experimental boat, the materials and structure of the transducer-hull, and the behaviour of the central and bow regions of the hull during sailing. |
