Hull & Deck Construction

This yacht is constructed from the most modern materials and techniques providing more strength with less weight than possible with conventional technology. The use of Kevlar modified epoxy resin And high density core materials allows the Marlow explorer to be stronger than the heaviest of hulls at a fraction of the weight. The use of modern resin infused vacuum assisted transfer is made on every counter, cabinet and sole in the yacht. The result is a yacht that cruises at 20+ knots when conventionally constructed yachts would only achieve 17 knots with similar power. Even if speed is not a driving factor for some, the increased range and reduced fuel costs will be of great benefit.
Other hull and deck construction aspects include:
