KM PR Range RIB's locates their fuel tanks under deck, maximizing the console space and lowering the centre of gravity thus improving trim and handling. Using stainless steel under–deck fuel tanks enable us to accommodate an impressive fuel load onboard, making extended voyages a reality.
Köser Marine GmbH are able to supply the engine of your choice and our preferred brands are Outboard engines: Suzuki, Yamaha and Mercury. Inboard engines: Volvo Penta, and Steyr, Z.- or Jet Drive.
The PR hulls are commercial strength Glass Reinforced Plastic (G.R.P.), into highly polished tooling moulds Lloyds approved chop strand mat and roving cloths are placed and laminated into position by PR's highly skilled laminators. All stages of construction are closely monitored to ensure correct humidity and temperature resulting in even curing and an immensely strong blister free hull. The cross linked inner matrix is then installed and once laminated into position the interior of the hull is gel washed to prevent delamination in later years. The hull is then de-moulded and stainless steel fuel tanks installed, the deck and internal mouldings are bonded into place and final deck finishing completed. The hull is now ready for the attachment of the inflatable collar.
The Inflatable Collar
PR is one of the few manufacturers to make their own Inflatable Collars. These are handmade to an Individual application or requirement by experienced experts. Buoyancy tubes are constructed from Hypalon®. Inflatable collars are unquestionably the leading material for the tubes due to its durability and more importantly ease of repair. The Hypalon® inflatable collars are cut and abraded on all bonding surfaces by our unique computer controlled cutting machine. The collars are formed into shape by hand, all internal and external seam tapes are bonded with Bostik® adhesives, the world leader in adhesive technology. The finished tubes are pressure tested to International standards before installation.
Köser Marine GmbH offer complete packages including engine, propulsion system, electrical/ electronic systems, trailers and stainless steel fabrication. All options can be tailored to individual requirements and professionally fitted to the highest standards by PR's factory-trained technicians. Köser Marine GmbH can design and install special equipment such as fully immersion proof electrics as seen on their lifeboat specification boats.
Console and Seating
Our consoles and seats are designed and manufactured to be practical and user friendly. We construct these by using the latest composite moulding technique known as Resin Transfer Moulding. This process ensures the highest possible level of strength and finish.
All PR boats from 4.2 m to 12.0 m are MCA (Maritime and Coastguard Agency) type approved. This means that the boat has already passed the relevant buoyancy, stability and approved build standards. You will need to have the relevant safety equipment on board and after inspection by the appointed MCA representative a license can be issued. For more information contact Köser Marine GmbH.
