The D-class (Dunlop) lifeboat is a class of inflatable boat operated between 1964 and 1969 by the Royal National Lifeboat Institution of the United Kingdom and Ireland.
For more than 60 years the D-class has served as the workhorse of the RNLI Inshore Lifeboat (ILB) fleet. The D-class is one of the few RNLI types not to feature a rigid hull. The D-class was specifically designed as a light and highly manoeuvrable rapid response craft, especially suited to close shore work.
