While the SR.N2 and SR.N5s operated in commercial service as trials craft, the SR.N6 has the distinction of being the first production hovercraft to enter commercial service. In comparison to the SR.N5, the SR.N6 was stretched in length, providing more than double the seating capacity. Some models of the craft were stretched further, enabling an even greater capacity. Experience gained in the development of the SR.N6 has been attributed as heavily contributing towards the design and production of the largest civil hovercraft to be ever produced, the

and studies into a prospective 2,000 ton freighter, there was also interest in developing its existing smaller hovercraft range.Paine and Syms 2012, p. 147. In particular, the company had observed there to be customer demand for a model of the SR.N5 that would be capable of carrying a much greater payload; there was a view that the existing craft was uneconomic for what payload it could carry and that an expanded, or 'stretched', model would be able to rectify this. According to Saunders-Roe's own projections, an increase of the craft's payload by 110 per cent would only reduce performance by 10 per cent as the increased payload was in part offset by the expanded cushion area, which meant that cushion pressure would not need to be substantially increased instead. The first craft to be lengthened in this manner, in effect becoming the first SR.N6, was the ninth SR.N5 to have been produced. Following three months of work to adapt the craft to the new configuration, this first prototype was launched for the first time on 9 March 1965. Portions of the SR.N6's development were performed in conjunction with

Further development

The SR.N6 had been designed in such a fashion that it could be extended from its initial 36 seat capacity to 58 without having to perform a major redesign or incurring high building costs.Paine and Syms 2012, p. 188. Work on the stretched SR.N6 was headed by Ray Wheeler, the chief designer of the

engine. Perhaps the most substantial change on the stretched craft, beyond the increased length, was the adoption of a twin-propeller configuration, which was done in order to reduce tip speed and thus noise.Paine and Syms 2012, p. 189. The first SRN6 Mark 6 Twin Prop hovercraft, also known as "Super 6" was conversion of a SR.N6 Mark 1, that had been used by Hoverlloyd and Pacific Hovercraft. Extended by 9 ft 8 in and given two 10 ft diameter propellers, it launched in 1973. Hovertravel produced its first stretched SR.N6, achieved with engineering support from the BHC, by converting an existing damaged SR.N6 and two SR.N5s.Paine and Syms 2012, pp. 188-189.


Design

The Saunders-Roe SR.N6 (also known as the ''Winchester'' class) is a medium-sized hovercraft primarily designed for passenger service.Paine and Syms 2012, pp. 147, 238. The initial models of the type were capable of accommodating up to 38 passengers, which was greater than the maximum capacity of 18 that could be carried by the smaller SR.N5. The SR.N6 was subsequently further stretched to accommodate a further 20 passengers; this capacity upgrade let to it being considered to be more viable for commercial operations than any previous hovercraft design. By eventually increasing the capacity to 58 seats, the SR.N6 Mk.1S became the first hovercraft to be capable of transporting a typical coach load of people. In a military configuration, the SR.N6 is capable of carrying up to 55 fully equipped troops, or alternatively up to 6 tons of equipment. The SR.N6 was powered by a single marinised model of the Bristol Gnome

.Paine and Syms 2012, pp. 148, 180-181. Around 20 per cent of the operating costs of the type have been attributed to maintenance of the 4 ft flexible skirt, which reportedly lasted for up to 500 hours, while similar cost levels have been reported for fuel.Paine and Syms 2012, p. 181. Early on, the SR.N6 was outfitted with an improved skirt, featuring ''fingers'' and forward puff ports, which resulted in improved forward control and reduced skirt wear; fingers had not been present upon the initial version of the skirt used prior to 1966.Paine and Syms 2012, pp. 134, 176-177. The endurance of the fingers would be progressively improved over time, issues with salt spray negatively affecting both the engine and propeller were also encountered early on. An initial experience of some components having short overhaul lifespans or being unreliable was encountered during early days.Paine and Syms 2012, pp. 221-223. During the early years of not only the SR.N6 but other hovercraft as well, the hovercraft skirt remained an unresolved area of difficulty during this era.Paine and Syms 2012, p. 166. The SR.N6 was piloted from a forward-seated position at the front of the main passenger cabin.Paine and Syms 2012, p. 148. The pilot would exercise control over the direction of the craft via a series of control surfaces that was located immediately behind the variable pitch propeller. Early on, pilots were normally aviators who had been recruited from the
