Since experimental trials in '63 the ILBs have proved so successful that there are now over 100 of them in regular use as well as the 135 conventional lifeboats. Last year, these tough, nearly indestructable craft, were called out 1,291 times; some two or three times a day.

For this sort of use as ever, reliability is the key word.

That is why with the engines that drive them, Duckhams outboard Two Stroke Oil and Duckhams Dryspark is in regular use giving the performance and protecting the engine.
