SS TUI – Kauri Clinker Steam Boat
It thought that Tui’s 15’ kauri clinker hull was built c.1920, then as part of her transformation to a steam boat the hull was restored where necessary and the exterior was fully clad in f/glass.For the steam boys I have reproduced the mechanical specs below from her tme listing (thanks Ian McDonald):

The boiler is of the Ofeldt type with a 6mm thick steel central drum and has 12 1/2″ copper coils surrounding it. The boiler is fast steaming, reliable and safe. Stainless steel cladding and stainless steel funnel. The steel firebox with adjustable dampers runs on char, coal and wood.

The 2hp engine is by Wayne Larsen and is single cylinder double acting 2.5″‘bore x 2.75″ stroke. It has a balanced crankshaft and semi balanced slide valve, with Stephenson’s reversing gear, twin boiler water pumps and a vacuum pump with exhaust steam passing through a feed water heater and keel condenser to the stainless steel hot well. The propeller is 14.5″ x 23″

An auxiliary boiler hand pump and is fitted with an electric water pump as a backup. A Stainless steel top-up water tank is in the transom with a stainless steel hot well placed just in front of the Boiler. A Steam bilge ejector is fitted for removal of any bilge water.

She is fitted with a Windermere Kettle to allow the crew to make a hot cup of tea/coffee on the run.
