Stormforce 11


The Stormforce 11 is the flagship in our range, and offers the best that RIBs can offer. The 11 was a natural development from the 9.1, due to customer demand for a larger RIB. Puffin Dive Centre in Oban took the first two boats out of the mould for their operations on the West Coast of Scotland. Since then, the 11 has developed and continued to grow in its popularity; every 11m RIB is unique and customised according to the customer’s requirements.


The Stormforce 11 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; this ensures that the RIB has maximum stability.

One of the major design features is the Hard Nose. This was developed due to several reasons, and has proven itself one of the most successful features on this design after many years in testing. The Hard Nose is primarily a safety feature. When a RIB such as this is driven hard in a large sea state, there is a real risk that detubing could occur. Thus, the nose is designed to offer complete protection to the tubes when operating in these conditions. Furthermore, there are actually two independent tubes on each side of the hull, offering even greater safety.

The other features of the hard nose are mainly from a practicality need. The GRP nose offers a much more suitable platform from which to anchor or moor, without any problems with damaging the tubes. It also offers much more internal space; this was incorporated into a large dry storage locker, and in most models facilitates twin berths.
