The tug Lyttelton and her engines were built in Scotland in 1907 by Ferguson brothers Ltd. of Port Glasgow, and was sailed out to Lyttelton through the Suez canal which had been open for almost forty years. The machinery has been very little altered throughout the ship's long period of service with the Lyttelton Harbour Board and gives the visitor a glimpse back in time to the heyday of British steam engineering. On a visit to the engine room and stokehold you can very easily imagine the ship steaming out across the Indian ocean in 1907 lit only by oil lamps, with every spare space loaded with coal for the long voyage.
