Next question.
Why are the typical fishing boats in the Baltic so large?
Here the typical North Sea trawler does not come anywhere near 5000 tons.
Or is that another one of these ‘examples’ by the professor?
Edit: according to Eurostat, the average size of an EU fishing vessel is 19 gross tons.
You’re saying the typical baltic fishing vessel is 250 times as large?
Edit 2:
According to Eurostat in 2010 there were more than 85000 fishing vessels in the EU.
Of these 85000, there were 90 which were larger than 2000 tons.
Most of these were from France, Spain, the UK and the Netherlands.
Sweden fot example had none (in 2010) of this size, let alone of 5000 tons.
And.... edit 3.
You can find the data for 1994. In the whole of the EU there were then 50 fishing vessels, larger than 2000 tons. None of them owned by Sweden.
So.
Where is your declaration of 'a fishing boat weighing typically 5,000 tonnes' based in reality?
5,000 tonnes travelling at 1.9 knots was Amdahl polar end of the range of possible weight x speed that could have caused a similar impact hole in a ship of the Estonia's specifications, 15.5K tonnes presumably travelling at 15 - 18 knots ranging down to 1,000 tonnes at 5 knots ( fixed factor ditto). He said a fishing vessel as the only likely extreme that could fit one end of the spectrum of possible vectors with the submarine the lower end, as there aren't many submarines below that weight, nor fishing vessels as heavy.
[aside: The Baltic is rich in fish, my uncles often caught fish there, both by throwing hook fishing tackles into the sea as far out as possible, preferably from an island or boat, together with setting overnight nets via boat. One or other would often drop by our summer cottage to leave a freshly caught and smoked fish for our dinner. In fact the Ahvenanmaa - the Finnish term for the Åland Islands means 'perch-land' as it is rich in ...perch and numerous other species of fish. The Baltic Sea is the country of the perch tribe.]
But of course, that doesn't mean Amdahl was claiming there was a 5,000 tonne fishing vessel there, it was as an illustration of the upper end of the range of possibilities. You don't know, poachers could in theory turn up to fish in illegal waters. You've seen the French, the Brits, the Dutch and the Norwegians constantly battling over this in the North Sea.
