Stormforce 9.1 Cabin


The Stormforce 9.1 by necessity is a deep V hull form which is one of the reasons that this RIB has such fantastic abilities in rough offshore conditions. The Deep-V hull is combined with sprayrails to produce additional lift and improve the hydrodynamics of the hull. The tube is designed to sit firmly in contact with the water surface while at rest, ensuring that the RIB has maximum stability.


The cabin has been shortened, but still provides adequate seating for 4 on Air Sprung Suspension Seats and the cabin also includes a spacious double berth and the standard 11m console. Other internal options could include a small galley and toilet cubicle etc.


On the decks, wide side decks run the length of the RIB giving excellent access around the cabin and a large engine bay occupies the rear of the vessel, with enough room for a twin diesel installation.

This RIB is ideal with twin diesel sterndrives, which offer a good turn of speed with excellent fuel efficiency.


The Stormforce 9.1 was designed and developed inhouse to meet the needs of our customers who required bigger and safer RIBs. The main instigator of the 9.1 design was our longstanding customer, Julian Cooke, who had worked his way up through the range of smaller Ribs. Julian originally bought a 6.1 Redbay fitted with a 100hp Suzuki which he used for a season before moving onto a twin outboard 6.1. Next move was to a 7.4 fitted with a single Mercruiser 180 diesel engine and with the Scottish Islands on our doorstep, Julian began discovering the delight of many of these Islands. With longer weekend trips and the need for more reliability, we began discussing a twin inboard engined RIB. For improved reliability and safety, one of the main design criteria of the new RIB was that it must have twin engines.

All Julian’s cruising experience and recommendations were recorded and a new design was built around these. We decided on a hard nose boat with safety at the top of the list. Then the boat had to have twin diesel engines (capable of 15-20 knots on one engine), independent electrical and fuel system, large storage areas and a well protected seating area etc. From our cruising experiences, we recognised that the bow of the RIB was only used to strap down luggage and as an anchor locker/platform and that mooring or anchoring is often difficult with a conventional high bow. Furthermore, a diesel RIB driving its weight into a bad following sea would run the risk of detubing if stuffed into the back of a wave.

Our hard nose overcomes all these problems and provides a mounting area for three cleats and bow roller, anchor and anchor winch. The hard nose is entered through a fibre glass door and inside it houses an anchor locker, space for an inflatable tender and masses of dry storage. The last and most important feature of the highly flared nose is that it gives total protection to the tubes, and in the event of a big sea, the buoyancy provided by the flare pushes the bow up immediately.

Julian’s boat was almost a year in the planning and development but it was worth the wait!

Shortly after the 9.1 entered production, Puffin Dive Centre in Scotland approached Redbay with the need for a longer version of the 9.1. Subsequently, we lengthened the mould, with the intention of returning it to the original length after the two Ribs were built for Puffin. However, the mould was never shortened, and the 11 metre has proven to be one of the main success stories of Redbay Boats.

The RIB can accommodate the side by side open console, with additional POD seating if required
