Propulsion and deck equipment for S/V ‘Waratah’
Meanwhile the engine for ‘Waratah’ has been ordered. I chose for a Yanmar 4JH4AE, which provides a maximum output of 54 hp at 3000 rpm. It will be equipped with a straight Hurth ZF30M reduction gear, gear ratio 2.15:1, and multiple mechanical plate coupling. The engine is supplied by IMS Engineering Cape (Pty) in South Africa.
The engine comes with a 12V - 80A alternator for the starting and control system. An additional 24V marine alternator will be added to charge the house bank. The final choice is still pending at the moment.
For the 38 mm diameter propeller shaft, a so called ‘dripless’ PSS shaft seal by P.Y.I will be installed. The propeller is a 2-blade fixed propeller, 18″ x 15″, and will be supplied by Central Boating in Cape Town. I am still looking for a suitable shaft brake, to prevent spinning of the propeller shaft while under sail.
Central Boating will also supply most of the deck equipment, like anchor windlass (Lewmar horizontal anchor winch, 24V DC with gypsy and manual override), hatches (Lewmar), winches (Lewmar), and most of the other deck fittings.
