The D class inflatable is small and highly manoeuvrable, making it ideal for rescues lose to shore in fair to moderate conditions, particularly in the River Tay with its dangerous sandbanks. It has a single outboard engine and can be righted manually by the crew following a capsize. Broughty Ferry was one of the first RNLI stations to operate a D class in 1964 and the design of the class has continued to evolve since its introduction. The details given are for the latest version that was introduced in 2003 and stationed at Broughty Ferry in 2008.
