Severn Class Lifeboats

Developed in the early 1990s, the Severn class was introduced into the fleet in 1995 and is designed to lie afloat, either at deep-water moorings or at a berth. The severn class is currently the largest in the RNLI fleet.

The Severn has a sheerline that sweeps down for ease of survivor recovery. She is inherently self-righting and should it be knocked over in extreme weather, it will automatically right itself within a few seconds.

Her propellers and rudders lie in partial tunnels set into the hull that, along with the two bilge keels, provide excellent protection from damage in shallow water.

In addition to her twin engines, the Severn is fitted with a hydraulic-powered bow thruster for improved manoeuvrability.

The Severn carries a small Y boat, which is an inflatable daughter boat complete with a 15hp outboard engine. This small craft can be launched with a crane and is used in moderate conditions to access areas where the lifeboat cannot reach.

Severn Life Extension Programme (SLEP)

The largest and most powerful class of lifeboat, the Severn entered service back in 1996 and there are currently 44 of these 42 tonne lifesaving vessels in the charity’s fleet. With an operational lifespan of 25 years, these amazing lifeboats are now approaching retirement age and are due to come off service soon.

However, the charity’s expert in-house engineering team has worked in partnership with academic and industry experts, establishing that the lifeboats’ hulls can continue operational service for another 25 years. Through a life extension upgrade, the Severn’s wheelhouse will be completely redesigned and a wide range of upgrades will be made, ensuring the vessels can operate safely and effectively for another 25 years.

As well as fitting the lifeboats out with more modern and sophisticated technology and systems, the upgraded Severns will have significant safety enhancements to ensure the RNLI’s volunteer crews are as safe as possible while out saving lives at sea in all weathers.

In 2025 the RNLI announced following a following a fleet review, the Severn Life Extension Programme would not be continued beyond the two boats already in the programme.

The RNLI now plan to withdraw the Severn class lifeboat fleet over the next fifteen years.
