Part one....A right hand prop, when viewed from astern spins a)
clockwise or
b) counterclockwise when operating in the fwd direction?
"A propeller that drives a boat forward when it rotates clockwise - as
viewed from astern - is called a right handed prop.
Part two.....a RH prop, when backing with rudder amidships imparts
movement
to a) port or b) starboard?
"A single right-hand wheel will tend to push the stern to starboard when
going forward ( to port going astern)".
Part three...is RH or LH rotation more common for trawler sized
(40') single
screw boats?
."Right handed props are almost, but not quite, universal on single screw
boats".
Is there a good mnemonic to remember this?
