Aside
from all the valid points already posted here theres another to consider.
Rules of the road.
As in driving vehicles on the highway.
In MOST countrys of the world eg USA - the road rules are very 'similar' to the boating right of way rules, what with vehicles being left hand drive, & keeping to the starboard (RH) side of the road being the same as for vessels in channels etc.
i.e. for a vast majority of the worlds inhabitants in LH drive vehicles, their natural "reaction" to an approaching vessel is to swerve to the right, which in 'marine rules of the road' is the correct thing to do.
Where the confusion arises is - in having a RH (Starboard) helmed vessel for these poor left hand drivers, who are conditioned to stay to the right!
It would be a LOT more natural for Nations with left hand drive vehicles to so helm their vessels to port so that occupants react naturally the way they would on the road in an emergency situation.
Where the argument falls down of course is when in upside down land where we have RH drive vehicles, and keep the the LEFT of the road.
When in a boat our Natural instinct upon seeing an approaching vessel is to keep left (to Port) while the international nav rules require in fact that we do keep to starboard (right).
This alone is hard enough an natural instinct instinct for us to overcome when in a vessel, without confusing the issue more and putting the helm on the "wrong siode of the boat for us" i.e. Port - you see we are used to RH drive vehicles, and keeping to the left.
I contend to you all that for us downunder - we should helm boats to starboard, just like our vehicles AND that way we ONLY have to overcome the confusion of holding hard to starboard (right) rather than the second confusion of being seated on the wrong (port) side of the vessel compared to our vehicles.
Put an Aussie in a Port helmed vessel, and expect him to obey International nav rules of right of way is to ASK for trouble...
You see Aussie men can't do two things at once - it's a well proven scientific fact - which my dear wife (Mrs T or more often the recipient of the appelation "She who mistakenly thinks she wears the pants") ASSURES me this well known scientifically proven fact is the reason I will NEVER die in my sleep.
So there you have it Port helmed for the Yanks and Starboard helmed for us handicapped Aussies!
Nothing like an each way bet!
Cheers!
