Previously used for towing duties and now utilised for warping the ship alongside when berthing the Aft Winch has plenty of power with its 12in by 12in stroke!
The boilers were constructed by Messrs. Barclay, Curle & Co., Ltd., of Glasgow and are of the cylindrical type, 13ft. 6in. in diameter by 11ft. 6in. long, and are arranged for coal-burning. Arrangements for forced draught on the Howden system are incorporated. The feed pumps have been supplied by Messrs. G & J. Weir, Ltd., of Cathcart, Glasgow, and each is capable of dealing with the requirements of both boilers. A Hocking combined feed-heater and filter is also fitted.

The centre fires are lower than the wings and are used for lighting up as they are low and assesable as well as create even convection currents around the cicular boiler. Copyright Godfrey Down

With 13 separate steam engines in one room, the Daldy’s engine room can get to be quite a busy place. My personal favourite is the main port engine. It always seemed to respond better than the starboard one!
The cylinder diameters are 15, 25 and 40in., the stroke being 30in. The high-pressure cylinder is fitted with a piston valve having Moss Philip rings, while the intermediate- pressure and low-pressure valves are of the Andrews and Cameron type. The piston rings are of the Lockwood and Carlisle type, and United States metallic packing is fitted to all the piston and valve rods. The exhaust from both engines is led to a common condenser, arranged athwartships at the after end of the engine-room. Two independent air pumps of the Weir design and a Drysdale centrifugal circulating pump are installed.
The W C. Daldy is generally handled from the flying bridge, otherwise known as the Monkey Island. There are various Masters and the minimum requirement to handle the vessel as Skipper is a Commercial Launchmasters Certificate.
The funnel received a major overhaul in 2002. The outer skin was patched and rivet tops were welded on to make it look as original as possible. It received a complete stand blast and a fresh coat of paint. The internal flue will eventually need to be replaced as it is in poor condition! A funnel cap which works in a butterfly fashion can be opened and closed internally from on top of the boilers, using a lever and pulley arrangement.
The original coal range has been removed due to extensive rust. During the delivery voyage, the ships Cook was said to have gone mad in the heat and disembarked the ship at Darwin. the galley also contains a steam powered tea urn.
The current lifeboat on the W C Daldy is merely there for show and is a lot smaller than the original, which was hung in davits on the starboard side of the tug. It was soon relocated to its current position and then later removed as it hindered towing operations.

This area houses the only non steam powered engine on the tug. It’s a single cylinder Lister-Petter diesel engine of ancient origins. It has a decompression lever and is crank start. Most often, it requires a good sniff of ether before it coughs into life as the emergency fire pump. It is a requirement by NZ maritme law to have an alternative fire fighting pump. If there was a real emergency I’d put my money on the real fire pump in tne engine room!
