I remember asking this question loooong ago and my Dad and Uncles explained it this way: in a single engine boat the rotation of the crank and prop tended to raise the starboard side of the boat. To balance this effect the helm was placed on the starboard side to compensate for the torque lift. I always figured twin engine boats had the helm starboard also simply to avoid re-tooling for a port side location.

Mostly foot throttles don't need right handed throttle

Let be honest... nobody knows...

This is the main theory behind it all but oddly enough the last 6 out of 7 boats I've had all had port side steering.

A conspiracy it is, blame it on Obama

This one from Miami has a Port side helm and LH rotation drive...

Noah had a starboard helm so he could oversee the animals being loaded on the right side of the Ark. It's in the Bible.

Hi!

In a single performance boat your steering wheel is on your starboard side to offset prop torque. Normally your battery too to balance the boat running high on the pad / keel.

Spent my entire lift driving right hand side boats with throttles to the right. Most higher performance boats put throttles between driver and left side passenger, probably so a qualified throttle man can sit to the left.

While I'd prefer my future cat to have throttles to my right, if Tres Marine wants to teach me to sit on right and use left hand on throttles, that's what I shall do.
