Re: Steering on the right
I think your right. It is late and you've had to much time to think. lol
In searching the internet, you will find tons of theories from Nordic influence, British influence, the way props rotate, throttles set up for right handed people, etc. I don't think anyone really knows.
Many large bridge yachts have the steering in the center.
My project boat, 81 Sea Ray Sedan Bridge, had the steering on the left. That's now gone as I am putting the steering on the right. Not for any of the reasons people are likely to post here. Its because the bridge is small, the ladder (converting to staircase) is on the left and it will make bridge access and layout nicer.
Hope you get a real answer, if there is one. Good luck.
