Forgive an ignorant question: are you not out of EU waters at any point between the UK and the Canaries? Or even if you are, do you have to be in non-EU national waters, and not just international one, to reset the clock?
To get around customs / immigration rules on ships ... just sail outside territorial waters - make a log entry backed up by data archive ........... bobs the proverbial.
