Fuel Systems

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.

The Hull
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.
