Utilization

There were only 4 Avon S650 utilised by the RNLI as part of the D-class, the workhorse of the RNLI inshore lifeboat (rescue) (ILB) fleet. Significantly smaller in comparison to the rest of the inshore fleet, the D-class is also one of the few RNLI types not to feature a rigid hull. The main aspect of the boat would be both its size and weight, the D-class was specifically designed as a light and highly manoeuvrable rapid response craft.

Design and construction

The D-class lifeboat consists of two sponsons, together housing four inflatable segments intersected by baffles.[2]

This was one of the smaller classes of lifeboat operated by the RNLI, and while there were only 4 Avon S650s in the fleet, the D-class were a common sight at lifeboat stations around the coast. Unlike other members of the ILB fleet, the D-class does not have a rigid hull; all others, with the exception of the Arancia, hovercraft and ALB Tenders, are Rigid Inflatable Boats (RIBs).
