Mariner Multiple Citizenship Turkey/UK

Dear Guys!

I really wonder a thing. I m from Turkey and my seaman’s book is also Turkish. I have a Turkish and EU citizenship. But because of countries alphabet my name is different on passports.
e.g Güner(on Turkish passport and seaman’s book) / Gyuner ( on my EU passport).

So when I embark the ship from EU, do I need shengen visa?

Normally I dont have any problem for travelling but I have never embark the ship from EU so I want to ask.

I am looking for your answers and thx in advance…

Removed due to old thread. Let us know how it went - thx.
