Safehaven’s new mono-bow catamaran hullform
Irish Boatbuilder Safehaven Marine has announced that it is developing a new model to add to its extensive range of commercial and naval craft: ‘XSV20’.
The design is a high speed patrol / S.A.R and interceptor with a moulded length of 21.5m and a LOA of 23m (75ft). The hull design is extremely innovative (Patent applied for) and seamlessly fuses a twin stepped asymmetric catamaran hull form with a wave piercing monohull, to create a hybrid design that delivers the rough weather and high speed dynamic transverse stability of a catamaran, with the steep head sea capabilities of a deep V monohull. The hull mould is now completed following a 6 month R&D programme, during which Safehaven built 12 scale model variants which were extensively tank tested to optimise the design’s performance characteristics and hydrodynamics.
The first of class XSV20 demonstrator currently due to commence construction will be powered by four Caterpillar C8.7 650hp engines, through ZF gearboxes to France Helices SDS surface drives, she is projected to have a maximum speed well over 50kts, a 40kts+ cruise speed and a range of 800nm. The design incorporates all the features of Safehaven’s smaller 11-17m Barracuda range of naval craft, with greater endurance, payload and crew capacity. The design has been developed, as Safehaven’s designer and MD Frank Kowalski succinctly puts it ‘In one’s endless pursuit of travelling fast in rough seas’ and should allow higher speeds to be maintained in rough sea conditions with greater crew comfort and safety than many conventional designs. The demonstrator is due for launch early next year.
