breehorn 37 Construction and certification
The Breehorn 37 is built in accordance with the European CE-certification scheme and meeting the requirements of the CE-directive 94/25/CE for pleasure craft CE class A.
This means that high standards are set for the constructional strength of the hull and deck, bulkheads, keel and rudder and the fastening thereof, safety and stability, engine installation, gas installation and the availability of owner documentation.
Hull and deck
Both hull and deck are constructed from glass reinforced plastic (GRP). The gel-coat and the first two polyester layers are of ISO N.P.G quality (isophthalic-neopentyl glycol (ISO/NPG) polyester resin) for superior weathering- and osmosis resistance. Above the waterline the hull consists of a sandwich construction with 20 mm PVC foam. A similar construction method is used for the deck. Longitudinal stringers and laminated bulkheads make for a very stiff structure.
The hull/deck joint is fully kitted with structural adhesives through-bolted with a stainless steel (s/s) bolt every 150 mm through an aluminium footrail with square holes. The construction is laminated on the inside for optimal strength.
The keel construction consists of a polyester skin filled with 3,250 kg lead. The keel is fixed with stainless bolts welded to a s/s frame. The keel is laminated to the hull with a double layer of polyester.
The rudder consists of an aluminium rudderstock with three pairs of welded cross plates, laminated and filled with foam. The rudderstock is supported by three bearings and protected by a full length skeg. A wooden laminated curved tiller is fitted with s/s fittings as standard
