D Class

The D class lifeboat is one of three classes of inshore lifeboat (ILB) – the B, D and E classes.

The D class has been the workhorse of the service for over 50 years. The inflatable D class is highly maneuverable and usually operates closer to shore than all-weather lifeboats and is specifically suited to surf, shallow water and confined locations, often close to cliffs, among rocks or even in caves.

In 2010, D class lifeboats launched 2,401 times and rescued 1,639 people, saving 103 lives.

The D class lifeboat has a single 50hp outboard engine and can be righted manually by the crew after a capsize.

First introduced into the fleet in 1963, the design of the D class has continued to evolve since its introduction and the latest version was introduced in 2003.
