Stormforce 8.4 Expedition


The design is a combination of the existing wrap around consoles and the full GRP Cabin versions of the Stormforce 11.

Initially, the basic concept was drafted in 2D from which a 3D model and subsequent renders were generated in house. This allowed the design team, mould fabrication team and the customers to view the design and revise details before construction. The 3D model was highly successful, and was used extensively in the fabrication of the moulds

Design Features

The obvious feature is that the Expedition has a full GRP cabin which has allowed us to manufacture an extremely strong and safe RIB, fitted with wrap a around toughened glass screen for maximum visibility and safety. This has resulted in low noise levels in the cabin, leaving a very pleasant ambience for offshore cruising. Access around the cabin is via wide side decks.


The Expedition also brings several features previously only found on our larger RIBs, such a the hardnose. Over the years, the hardnose feature of the Stormforce 9.1-11 has proven itself very worthy, and it was felt that this feature should be incorporated at an early stage in the development of the Expedition. The hardnose has the most important safety feature of helping to prevent detubing, a risk when offshore cruising in large seas. It also provides a secure anchoring point, and in the Expedition version we have fitted an anchor locker within the nose, to make full use of this benefit. The hardnose has also allowed us to do something that would have otherwise been quite difficult; fitting two berths in the bow whilst also providing a lot more storage space. There is also adequate room to comfortably sit upright in the forward cabin; this was another of the major requirements for the new design. In effect, we have ensured that the total length of the RIB is utilised in some way.


The stern/engine bay arrangement was also developed from design details of the larger Stormforce RIBs. This is highly advanced in reducing and eliminating spray and sea water from entering the engine bay and reduces any risk of the engine flooding. It also provides a large seating/sun lounging area aft.

Interior & Fitout

The most striking feature about the interior is just how airy it is which helps to ensure maximum comfort for all on board when at sea. The interior sides, rear seating, console, exterior deck, sides, bow and engine bay are all taken from the one mould, ensures the highest quality finish, reduced build times and is perfect for the lower sides of the cabin which can be subject to the usual bumps, knocks and mucky fingers!


Along with having two moulded side benches with integral storage aft, Expeditions are normally fitted with four High Back Comfort Seats with storage beneath as standard. The High Back Comfort Seats add a higher level of comfort and security than traditional RIB seating arrangements and Air Sprung Suspension versions are also available.
