GL: Whistles-coming upon a Tow

[The Clares]

Seems like lots of ambiguity on this topic. My take(see John Gills web site
article,also):
Upon sighting a tow,  you should ask what HIS passing or overtaking
preference is,and upon hearing the somewhat mangled "seeyaondaone" He is
saying ,that when you pass or overtake HIM, HE wants to see you on HIS port
side,therefore you steer whichever way puts you passing him on his port
side. Obviously the way you steer to accomplish this is different if you are
passing his front or overtaking. "onthetwo" means the opposite,ie. when you
pass him, either way, he expects to see you on his starboard side.
