Inflatable lifeboats were introduced to the RNLI fleet to help crews reach areas close to shore, cliffs and caves. These inshore lifeboats remain the workhorse of the RNLI today.

These fast and small lifesaving craft answered the need for a quicker and more agile response to rescues in areas of water that are not necessary suited to the large all-weather lifeboats. 

The first inflatable inshore lifeboats were introduced in to service in 1963; they were constructed using a tough nylon material proofed with neoprene. Powered by a 40hp outboard motor engine, they could reach speeds of 20 knots or more. They measured 15ft 9” (4.8m) in length.

Whitby received its first ILB in 1964, and over the last 50 years, our D Class ILBs has proved itself invaluable in saving lives at sea. This craft has enabled crew to reach, rescue and save people in seemingly impossible situations, including those stuck on cliffs, stranded on rocks and trapped in caves. 

Today’s D class inshore lifeboats can carry up to three crewmembers and are powered by a single 50hp outboard engine. 

Onboard equipment includes both fitted and hand-held VHF radio, night-vision equipment and first aid kit, including oxygen.
