A school, a coastline and a problem
The rigid inflatable boat, usually abbreviated to RIB, has an unusually well-documented beginning. It came out of Atlantic College, an international school founded in 1962 at St Donat’s Castle on the Glamorgan coast of South Wales. The school was started on the ideas of the educator Kurt Hahn, and from the outset it included service to the community as part of its programme. Because the college stood on a stretch of coast with strong tides and a record of casualties, its students set up a sea rescue service.
Early on, the college’s rescue service was run under the guidance of Desmond Hoare, a retired naval officer who was the school’s first head. The students were not experienced rescuers, so the boats had to be easy to operate, fast and forgiving.
What they started with
The college began with the types of boat then available, including conventional rigid boats and the inflatable craft that had become common after the Second World War, as described in the article on rubber boats. Each had drawbacks. Rigid boats were liable to be damaged in surf and were hard on anyone or anything they struck. Early inflatables were soft and safe to approach a casualty with, but they were slow to plane and difficult to steer in a seaway, and their floors were flexible.
According to the usual account, Hoare and the college’s people combined the two ideas, giving an inflatable collar a solid, shaped bottom. The result was a boat with the stability and impact tolerance of an inflatable but a hull that could be driven at speed. The precise sequence of prototypes and who contributed which detail is told in various ways in different sources, and it is safest to describe the invention as a collaborative development in the early 1960s rather than the work of a single designer.
Why the idea worked
Several features made the combination attractive. The inflatable collar gave buoyancy and stability, and meant that a boat could be driven alongside a vessel or a person in the water without causing injury. A rigid V-shaped hull allowed the boat to be steered accurately at higher speeds than an all-inflatable boat. The craft were also light enough to be launched from a beach or a trailer by a small crew. The engineering of the hull, collar and attachments is described in a separate article on the rigid hull inflatable.
Adoption by the RNLI
The Royal National Lifeboat Institution was already taking an interest in inflatables. It began using small inflatable inshore lifeboats in the 1960s, and its trials showed that fast inshore boats could save lives in situations where a large lifeboat could not reach, such as close to cliffs or in shallow surf. Atlantic College’s example led the Institution to consider rigid-hulled versions, and in the early 1970s it introduced the Atlantic 21, a RIB developed with the college and named after it. It was a 21-foot (about 6.4 metres) craft with twin outboard engines, and it became the basis for a series of successors. Later versions of the type, with names such as Atlantic 75 and Atlantic 85, followed in the decades that came after, and the RIB remains an important part of the lifeboat service today.
The adoption of RIBs sat alongside the Institution’s larger all-weather lifeboats, not in place of them. A RIB’s strengths are speed and manoeuvrability in moderate seas near the shore; larger boats remain better suited to long offshore work in severe weather.
Spread to other services
Other rescue organisations noticed the design. Coastguards, fire brigades, harbour authorities and independent rescue groups around the world adopted RIBs for inshore and river rescue. Some independent lifeboat stations, which are community-run, chose them because they were cheaper to buy and to operate than traditional lifeboats. Naval and police forces also adopted the type for patrol work, boarding and harbour security. Their further military and commercial use is covered in a separate article.
Safety and limitations in history
Historically, RIBs were not free of problems. Their speed could be a hazard in rough water, and early crews had to learn how the boats behaved when driven hard across waves. Over time, builders and operators developed improved seating, handholds and training, and the design settled into a recognisable form. This remained an evolving field rather than a finished one, and the type continues to be adapted for different tasks.
Legacy
The RIB is an example of an innovation that arose outside the usual shipbuilding circles. A school and its students, working on a practical need, produced a type that became widespread. Its influence on sea rescue in particular was substantial, and it changed what coastal rescue looked like from the 1970s onwards. The type is now found across the world, from rescue stations to ships’ boats to leisure craft.
