Power Profile

Yanmar Australia

The Southwinds was designed in 1948 and built in Sydney in 1950 with Huon Pine planks.

The Ketch has even competed in Sydney to Hobart yacht races.

Purchased by Finn Irvine, the Southwinds went through a complete restoration at Noakes’ yard in North Sydney, which included replacement of the old engine with the state of the art YANMAR 4JH110 marine engine driving a Gori 3 blade folding propeller.

There were many challenges along the way, trying to fit the engine into the engine space available and also fitting the Gori folding propeller, which required some special modifications of the rudder to make it fit.

The owner is very happy with the end result, with a very quiet and fuel efficient engine installed, great performance and maneuverability from the Gori propeller, making the Southwinds one of the best charter yacht experiences you can have on Sydney Harbour.
