Hello,
I am interested in becoming an ordinary seaman but I am totally inexperienced and do not possess any degree/certificate regarding seafaring; also, I am almost 26 and because I want to complicate things a bit more, I am not British but remain continental [I do possess higher education degrees, if that helps

].
SO after some digging over IP, I have found that the Yankee term for OS in the UK is actually Deck rating grade 2 and that :
successful completion of the approved basic training - in this case they must also hold a navigational watch rating certificate
an efficient deck hand certificate
a level 2 vocational qualification in marine vessel operation, in which case they must obtain a watch rating certificate within one month of joining the vessel
are required; which sucks.
Is there any way whatsoever to bypass these mandatory certificates and just get enrolled on a ship ?
And no, I do not wish to come back to my old country.
