PRODUCTS & SERVICES Marinetek launches sauna-on-the-move SaunaBoat, an innovative floating sauna concept developed by Marinetek for its private customer base in Finland and Sweden, could find an alternative commercial use in the marina sector. Available in two sizes and with a host of options, it combines a floating terrace and traditional Finnish sauna with a boat, when registered in the EU with the necessary CE certificate. It can move and moor up wherever required. The SaunaBoat 14, a 10.2m (33.4ft) boat with 14m² (150.6ft²) of space is ideal for larger gatherings. Able to host up to 12 people, it is divided into two rooms, i.e. a sauna and dressing room, and a separate toilet cabin. It also has a good sized terrace with space for sunbathing and a barbeque. The smaller model 10, at 8.3m (27ft) in length with 10m² (107.6ft²) of space is perfect for family use and, like the SaunaBoat 14, can be fitted with a sleeping cabin instead of sauna if preferred. It also enjoys plenty of outside deck area. Cabins for both models are of timber construction and sit on timber decking, and the saunas rely on traditional wood burning stoves. The cabin is mounted on a hotdipped steel framed platform with plastic tubes that has been built using Marinetek’s proven pontoon technology. The SaunaBoat is strong but light in weight, can be transported by road if necessary, and is smooth and stable on water. It is easily and safely handled when fitted with an outboard engine of 15 to 20hp and has a cruising speed of 4 to 5 knots. Optional extras include shore power connections, solar power, LED lighting and a grey water tank.

An excellent project example in 2015 involved completion of a floating pier project in Lahälla, Sweden to accommodate up to three tugs weighing 1,100 tons apiece. The special design had to allow for cast-in service tanks and be able to support heavy trucks. Units weighing 250 tons and measuring 2.7 x 10 x 23m (9 x 33 x 75ft) were connected to create a 46m (151ft) long industrial pier with 140cm (55inch) freeboard in an exposed location. The technology for the floating pier, although used in this instance in a commercial application, has been developed as a costeffective, low maintenance means of mooring superyachts and, due to the high degree of engineering involved in elements such as connectors, can be adapted to suit any application requiring substantial freeboard and heavy vehicle access. SF has also been focusing on exciting new technology for the construction of lighter concrete floats. SF X-line and SF Prodock – two SF product lines introduced during 2014/15 – are basalt fibre reinforced pontoons suitable for use in protected locations where wave height is less than 0.3m (1ft). Basalt is a natural volcanic igneous rock that reaches the surface of the earth as molten magma. It is mined as a raw material and there is no limitation in terms of supply. The corrosion-free nature of the basalt enables structures to be lighter at equal or higher strength than The technology for the floating pier in Lahälla was developed with superyachts in mind. concrete as no concrete layer thickness is required to protect the reinforcement from corrosion. This allows for better overall costs as transportation and mooring can be achieved more cost effectively. The lack of any corrosive cast-in material also means that the life expectancy of the basalt pontoons is estimated to be very long (potentially 100 years). In terms of lifecycle cost for floating concrete structures this is a huge leap forward. The technology has been developed in-house at the SF Marina factory in Wallhamn and the technology is now patent pending. Contact SF Marina in Sweden on email: 56 - May/June 2016

PRODUCTS & SERVICES Swift installation for twin module attenuator A new wave attenuator to protect a 36-slip marina at Rosario Resort & Spa on Orcas Island in the San Juan Islands of Washington State was installed in March. The structure was designed and built by International Marine Floatation Systems (IMFS) and is moored by Seaflex. Weighing 700 tons, the attenuator comprises two 230ft (70m) long x 16ft (5m) wide x 7ft (2m) high modules and has a freeboard of 2ft (0.6m). The head end portion is designed for floatplane loading with a 32ft (9.8m) wide x 36ft (11m) widening and has truck tyre bumpers. Designed and engineered with a concrete base to resist any torsional wave impact, it features just one connector joint. This is similar to IMFS’s standard rubber connector but is much larger, weighing 600lbs (272kg) and incorporating 2.5inch (6cm) cable bolts. Conduit chases are built in for water and electricity services, provision has been made for fire protection piping, and safety ladders have been fitted. The attenuator is moored using a Seaflex flexible mooring system. Fourteen units were used, each of which has ten strands or cables and measures 18ft (5.5m) in length. The units were secured using both rock and gravity concrete anchors. The use of Seaflex and the benefit of good weather significantly sped up the installation process, which took place in a single day much to the delight of the IMFS crew and the developer Strandberg Construction. Contact IMFS in Canada on email: imfs@floating and Seaflex in Sweden on email: Sublift for beamier boats Swede Ship Sublift has released a new version of its Sublift 12t machine to enable it to handle boats with a beam up to 4.8m (15.7ft). The modification has been achieved by replacing the 2.5m (8.2ft) wide cross beam with a 2.8m (9.2ft) beam or an optional 3m (9.8ft) tube. The new standard design makes it possible to straddle cradles up to 3.3m (10.8ft) wide although the Sublift machine is still under 3m (9.8ft) wide when in transport mode. The revised design has not affected the price. Contact Swede Ship Sublift in Sweden on email: - May/June 2016 57
