Motor recomendations for arab Dhow
« on: May 11, 2007, 04:42:46 AM »

I am going to build an Arab Dhow for my next project. From plans MM2097

I need recommendations for an auxiliary motor, ESC if needed, prop, and propshaft, batteries etc.
I am looking at spending the minimum.

She will be 72 cm long overall (50cm at CWL)
14cm beam
7 cm draft.

Primary propulsion will be sail.

What do you guys recommend. Main aim is cheap and cheerful

Mobile Marine Models do a reliable motor about the same physical size as a 480, but loads of power, I havew one driving a 55mm prop in a river launch. they are about a tenner and bryan does the coupling as well.

For a boat of this size and type, a 15 volt 385 type run on about 6 volts should be very adequate.  Dhows rarely planed.  Prop? Anything that looks sensible.
If its really just aux. power to limp back, it needs nothing more than a servo motor driving a small home-made prop.  The small prop should minimise the drag when not being used, the very modest power consumption could be provided for from a 4 or 5 cell RX pack.
