Waverley Excursions

Steam Engine

Steam Power

Waverley has everything to offer the steam enthusiast. At the heart of the Ship is her magnificent 2100 horsepower, triple expansion reciprocating steam engine, open to full public view.

Watch the Chief or 2nd Engineer operate the engine as we arrive and depart from piers on your cruise. The Engineer on watch will be able to answer any technical questions you may have (if he is not too busy!).

Also visible through portholes in the ship’s hull are Waverley’s famous paddle wheels, hear the clang of the telegraph as the Captain sends instructions to turn the paddles ahead or astern. View Waverley’s Engine Room here.

On deck, the crew operate Waverley’s steam powered Windlass at the bow and the Capstan aft as the ship arrives and berths at the piers we visit.

Almost all of Waverley’s machinery including the steering and all the main pumps are powered by steam from her two massive oil fired boilers.
