Monkeys on the road

I pushed myself Close to the North Racon.

I wanted to make this picture from forecastle.

There are not so many rules of the road which regulate collision avoidance. And they haven't been changed for many years.
Yet, many Officers can not see the full picture when applying rules.
Singapore Straight. Eastbound. My vessel is going Slow Ahead. There is a tanker behind.She is an "Overtaking vessel". Should overtake me and be responsible until I am past and clear.
She was following me for quite some time with the course showing intentions to overtake me on my straboard side.
Instead, the Officer there called me and asked me to slow down, so he could pass ahead of me to jin left part of the channel designated for deep draught vessel. The explanation was that he was Vessel Constrained by her draght. VTS also contacted my ship to advise me about vessel on my starboard side. But they mentiond that the vessel was also a vessel on my starboard side, which according to the rules I should also give a way.
Those are all good comments if You are not overtaking vessel.
I told that I would make a space for her to pass, so she could overtake me. In reality I made a lot of room, as I almost disappeared from her way.
There was plenty of room for both of us. I made a turn around Racon bouy in about 50 meters.
But many people who does not know and follow rules, they are also jerks.
That guy cut me moving to close. Maybe he wanted to come close to that Racon as well, but ended creating very unsafe situation. The closest distance in what he overtook me was about 40 meters. From his stern to my bow. And that was done on purpose.
Hey, You know what? Deck Officer and I am pretty sure that Captain was also on the bridge. So those guys on "BW UTAH" are bunch of assholes.
