Well Frederico,, SAR and such do not have much to do with Port State Control issues.
I was not in spanish ports for a whole while but according conversations between me and two others Masters of our fleet who were in Spain, the main tenor was, that they search until they find something. Of course one can say that the way it has to be, but running a ship is 10000 things to think of and the regulations are changing
quicker then they can be announced in these days were ships switching from standard navigation to paperless navigation systems for all ships withhin the next 2 years. I do not say that they should go too easy on ships, but personally I had a problem on a ship, where life rings were stored inside in order that they are not stolen in ports, and the PSC in that port wanted to make out of that a major deficiency.
A in port inside stored embarkation ladder for the forward life raft was also listed at that time as a major defie !!! I know personally from another ship that a stolen cap (copper) of the fireline was also written down as major defie. It looks sometimes the PSC think, they have to find and write down something as they are otherwise not doing a good job. But I agree fully with you a good PSC system should exist world wide.
