Steiner Nautic, based in Mattsee, has developed a new design in the over 100-year-old Schärenkreuzer class. The SSKF’s Swedish technical committee has approved the design and overseen the construction in collaboration with the Austrian surveyor Andreas Czerny. The shipyard has been involved in boatbuilding for five generations. Its range extends from traditional clinker-built boats through moulded constructions to carbon-sandwich electric boats. This breadth of expertise enables the shipyard to build in small batches for customers with specific requirements.
Requirements and Concept
The specifications called for a daysailer suitable for coastal use and trailerable. It should comfortably accommodate two people overnight. If required, the boat offers additional berths in the foredeck and under a cockpit cover. Its sailing performance should be suitable for regattas. The choice fell on a 30-square-metre archipelago cruiser. Alongside the 22-metre and 40-metre archipelago classes, this size is one of the most widely established classes internationally. The class rules of the Swedish Sailing Federation (SSKF) have defined the design parameters since 1908. This has a positive effect on the boat’s retention of value.
Design and construction
The hull is constructed as a sandwich structure with a red cedar core. The shipyard uses unidirectional and bidirectional fibre mats bonded with epoxy resin under vacuum. The wall thickness is 18 millimetres. Floor stringers and bulkheads reinforce the hull. In visible areas, the hull is fitted with a mahogany longitudinal veneer to give a solid wood appearance. The deck consists of a glass-fibre-reinforced sandwich with a balsa wood core. The surface is covered with teak. The total thickness is 18 millimetres. Deck beams support the structure. The superstructure uses 16-millimetre marine plywood with roof beams. The vacuum process ensures a strong bond between materials and a high fibre content. The pressure-treated red cedar core contributes to the rigidity. The combination of modern materials and a traditional appearance characterises the boat’s design.
Dimensions and sailing characteristics
The Schärenkreuzer has an overall length of 11.3 metres and a beam of 2.35 metres. Its waterline length when unladen is 8.09 metres. The draught is 1.59 metres. The weight is 2,310 kilograms. The mast rises 12.5 metres above deck. The rated sail area, from which the boat takes its name, is 30 square metres, in accordance with class rules. When sailing close-hauled, around 51 square metres of sail area is actually available. Spinnakers are available from 75 square metres. The freeboard height measures 0.81 metres at the bow and 0.65 metres at the stern. The deep cockpit offers safety. The aft deck comprises around 5.5 square metres of usable sunbathing area. Two large berths in the cabin allow for comfortable overnight stays. According to the designer, this classic long-keel yacht is intended to be agile to sail.
Rig and equipment
Rimmele Rigg Service from Immenstaad is supplying the rig. The rig is based on an aluminium mast profile from John-Masten. The design incorporates two spreaders. Raudaschl Nautic The sails are made by a company based in St. Wolfgang. The company represents Doyle Austria.
Quality control and surveying
The SSKF Technical Committee checks the design of the new archipelago cruiser to ensure compliance with the class rules. The inspection covers the measurement data and structural strength. The construction must meet the reference construction specifications set out in the class rules. Deformations under load must not exceed the specified limits. During construction, the committee, together with the Austrian surveyor, checks that the design is being implemented correctly. Upon completion, the vessel is measured by a surveyor recognised by the ÖSV. Registration takes place via the ÖSV Yacht Register as a 30-foot archipelago cruiser.
Completion and deployment
The boat is ideal as a relaxed day-sailer with overnight accommodation. Its class affiliation makes it suitable for regattas. The international presence of the 30er Schären class offers opportunities to compete. The fact that it can be trailered broadens its range of use. The combination of traditional class rules and modern design appeals to sailors who value something special. The Shipyard appeals to owners with a penchant for classic lines and contemporary build quality.
