The hull of this model is moulded in lightweight glassfibre, with a moulded in rubbing strip that forms seating for the 1.5mm PLASTIC deck.
The superstructure cabin is a vacforming in hi Impact styrene sheet and all deck structure parts are in pre-printed 1mm colour plastic.
To complement this most attractive model a full set of fittings in cast metal and resin is included along with propeller shafts, tubes and rudders.
To assist in the construction a full size colour plan with digitally embedded pictures of the prototype model is provided along with a complete set of comprehensive instructions, plus a set of decals to give a colourful finished model.
These high speed craft were designed and constructed in 1941 by British Power Boat Co for the Royal Navy as coastal Anti Submarine craft. Power by 3500 b.h.p Power Napier sea lion engines giving a top speed of 30 knots.
The craft were numbered from 22-39 + 49 The concept was that the craft sat in harbour and when a surfaced submarine was spotted these fast craft left harbour at high speed and attacked the submarine with depth charges. The twin .5 Vickers machine guns were used to keep the submarines guns crews suppressed. As these craft had no asdic fitted and the only methods of finding a submerged submarine was to stop and lower a hand held hydrophone over the side it quickly became clear that the concept was flawed from the start.
These craft were then used a Motor Gun Boats, but as they only carried light weapons and the top speed of approx 30 knots loaded they came off the worst when faced with German E boats with armed with 20mm machine cannons and a top speed of 40 knots.
At the time, early1941-42 they were used in the coastal force battles in the narrow seas of the channel as M.G.B.s the depth charges were dropped close to the enemy ships in the hope that the explosion would damage the hull. Lightly armed and with 3000 gallons of high octane fuel aboard they suffered horrific losses until replaced with more heavily armed craft.
Later used as Rescue launches even in this they were not effective as the access to the cabin was complicated and there was no space for stretchers for any wounded airmen and the harsh ride in anything but flat calm was very uncomfortable and could result in broken bones for the rescued survivors.
