Ok here is my understanding of the reason.

The propeller issue is one of the main reasons why steering wheels are located on the right side. As propellers spin clockwise, this motion tends to put the left side down. The port side is then pushed by around 2 to 3 degrees physically. In turn, the right side of the boat will significantly rise out. The weight of the one behind the steering wheel may prevent this rise and keep the ship afloat.
