RAPAKI


RAPAKI 1993 - Delivery voyage to NZNMM

Rapaki, the NZNMM steam crane, is moored at the northern end of Hobson Wharf in Auckland as a static display vessel and also acts as a breakwater for the museum's marina.

She was built of steel at Paisley in Scotland, by Fleming & Ferguson Ltd. and was equipped with a crane constructed by Sir William Arrol & Co., the builders of the Forth Bridge.

The Fleming & Ferguson yard and engine works had gained a world-wide reputation for quality small ships and steam reciprocating machinery. On 24th December 1925 Lyttelton Harbour Board ordered the 80-ton self-propelled floating crane RAPAKI for £42,000 to meet the port's demands for a heavy lift crane.

Four months later, on the 9th of April 1926 under the Scottish delivery master, Captain H. Liddell Mack, she made her delivery voyage to New Zealand under her own steam. The voyage, which took 109 days via the Panama Canal, was an eventful one, and RAPAKI faced a number of storms and shortages of food and coal. She was believed lost for a time when she almost ran out of coal on the East Coast of the North Island, eventually limping into Gisborne. Finally RAPAKI arrived in Lyttelton on 27th July, during a strong southerly gale and high seas. After a period of maintenance, on October 14, 1926, she was ready to work.

RAPAKI spent most of her working life at Lyttelton but saw war service in Auckland, and in the Pacific. She was retired from service in 1988 and purchased by the NZNMM in 1993. Towed to Auckland by the Navy Tug ARATAKI she has since performed as a floating breakwater and static display.

RAPAKI has a unique welded Scotch Boiler but the logistics of firing her systems by coal are immense, expensive, and difficult in a central city location.

She was steamed under coal for the last time in Feb 2001. The ôLive Steam Project' commenced with work to make the machinery spaces readily accessible to the public. The propeller shafts have recently (July 2003) been disconnected and modifications to the pipe-work have commenced to enable the main engines and auxiliary machinery to be operated (under no load) using steam from a self-contained boiler powered by gas or diesel.

We acknowledge funding support for this project from the Chisholm Whitney Family Trust and advice on boilers from Eaststeel Ltd as we move to bring live steam to RAPAKI as part of our exhibition and education programmes.

RAPAKI's sister vessel, HIKITIA is maintained in an operational status in Wellington NZ. She was converted to diesel fuelled boilers in the 1980's.
