You have to learn which is the cart and which is the horse.

The steering wheel is on the starboard side due to tradition.

Absolutely right. You see? You are both right.

P.S. My jet boat has the wheel on the Larboard side, but it also has a
foot throttle. The reason jet boat manufacturers give for putting the
helm on the port side (those that do) is because there is no prop
torque making it advisable to put the wheel to starboard, and it gives
most drivers the feel they are used to in a car.

But, why to props turn the way they do?
Why does the craft to the Starboard have the right of way?
Why is the helm usually to starboard?

No one but my three-year-old daughter would think me an expert, but I
would bet:
Norse tradition.

And why does Norse tradition put the star to starboard?
Probably because people are mostly right-handed.

So why is the helm usually on the right?
Human nature.
