Those who are not interested in the topic are free not to read it.
Those who are not interested in the nautical/ops aspect are free to open a new thread, where engineering aspects can be discussed at lenght and ad noseam .

Finally those who can not stand the presence of others here simply because of different thinking software c, an free themselves from the torture and ignore and/or block those whose presence is so irritating. So simple.
Finally , last I checked those bemoaners, voting and suggesting closure of the thread because they do not like other comments are kindly reminded they are not on the gCaptain government list of persons deciding what is relevant, what is not and what qualifies as spam.
No gusta?? flag it.
Simple rules and yet…
