Well, browsed the website for a while, used search engine as well and first few results that came of were about incidents where to blame were people of following nationalities:
- British
- Indian (or something similar, judging from his surname, when it’s not about Poles they don’t give nationality, which proves my point).
- Russian
- Polish
- British.

Thats all data from your website two years back. Somehow I fail to see significance of the Polish thread to British Marine Safety…
Now I try to look for your examples, sadly you did not bothered to provide any sources, googling.
First example from your list is back in 2007. Yes, he was Polish.
I can’t find any info about second example of yours, but it might be the situation where I was involved as an interpreter. If yes I can’t speak about it, but obviously I can confirm he was Polish.
Third example of your list: the man in question was Ukrainian. Ukraine, Belarus, Russia is quite a different world, altough still Slavic.
Fourth example of your list: Ukrainian (you worked with the guy and you can’t say the difference if he was Polish or not? That for sure makes you expert on the subject 
)
Don’t really have the time to look for the last one.
So what does it tell me?
Of your 4 examples of allegedly Polish people, one of them was Polish and one was likely to be Polish if we think about the same case.
If you look at the general list of the incidents, the Moon incident is a first serious one in last 5 years.
So what does it tell me? It tells me that you see what you want to see and therefore further discussion is futile. I made my point, you can feel free to believe whatever you want.
Alcohol on the rigs is a big no no, get your so called experienced friend to get his facts right, stick to your knowledge of little vans if I were you.
Yeah, keep believing in your perfect world 
Anyway, what he said was that “on the sea all nations drinks the same”.
Whiskey Galore was a fictional story about the factual sinking of the ss President and as a film may just have contained a wee bit of poetic license.ie.
Off course, but it is a picture of the culture in question. I refered to it as to example of drinking culture, not as a reference to marine incidents.
I’m on a roll now you got me started…
Oh, have fun. I hope you forgive me that I won’t be following it any more. I spend already 15 minutes vetting your claims and I already establshed that you just pick the incidents that are to support your theory.
I am not saying that all Polish seaman are golden boys, I am just saying that they are no worse, or no better than anyone else.
