Bavaria Technology - Hulls and Decks

Safety

Modern manufacturing methods guarantee a maximum of safety and quality. The shipyard uses only the most advanced GRP-technology. The result is a production that goes far beyond the requirements of the certifiers. And this does not only mean a plus in comfort but also increases the passive safety at sea and provides lasting value for each Bavaria Yacht.

The construction of Bavaria Yachts complies with requirements set up the European Union in the directive for leisure boats 94/25 and is supervised by the official classification companies. After an extensive testing of the prototype, the regular supervision comprises of checking the hull, the engine, the electric installation, all openings, through-hull valves and the sealings.

Laminate and Stringers - Backbone of each Bavaria Yacht

The lamination halls allow for an unprecedented high quality production of hulls and decks. All moulds pass a standard production cycle with a total of eight stations. Well proven hand lay-up is applied. Fully airconditioned lamination halls with permanent humidity and temperature control guarantee a consistent lamination process.

Hardeners are added by automatic applicators. Chopped strand mats cut for the each order guarantee a lamination structure according to the yacht's specification.

All GRP-products and moulds are kept in the airconditioned halls. This ensures the durability of the moulds, a steady curing process and therefore the quality of the ship´s body.

In each Bavaria Yacht, floor timbers and stringers are glassed in. Partially, e. g. in the keel area, the laminate is twice as thick as official specifications require.

Sandwich Construction - copied from the Aircraft Industry

Above the waterline and in the deck a sandwich laminated with PVC-foam core is used. The foam stability and the right material features are confirmed by independent certification agencies. The foam core is light weight but at the same time provides insulation and reinforcement of hull and deck. Sandwich constructions are an approved technology used in aviation industries and for ice-breaking ships. The sandwich layer is made of water repellent, closed porous foam which ameliorates the stiffness of the hull. Sandwich constructions have a very low heat conductivity which prevents condensation and makes the onboard climate more pleasant.

Osmosis Protection and Collision Reinforcement

The outer layer of the laminate structure is a conjunction of isophtalic acid resin and powder-bond chopped strand mats. This procedure ensures an effective water sealing as well as protection against osmosis.

In addition to conventional glass mats, there is a so-called multiaxial roving fabric used in the lamination. In order to minimise collision damages, for example by flotsam, endangered areas in the bow are protected by aramid fabric with high impact strength. Aramid fabric is the material which is used for making bullet proof vests.
