Oh, you don't even know. It's fucked. There are multiple licenses. I'm getting the third most basic one: only motor boats, up to 15 meters long, and only 12 miles off the coast xD So, not even sailboats, and I can't even go to the closest island from where I am, which is 100 miles away.
Oh and to top it all, apparently it's valid only within Spanish waters because Spain doesn't adhere to the international treaty that convalidates boat licenses -- even though they accept foreign licenses! But it's not reciprocated because reasons (basically it's because Spain is a third world socialist country that regulates leisure boating under the jurisdiction of the Merchant Fleet instead of being like a normal civilized country)
That's crazy - apparently I need qualifications if I'm going to bring her to Spain...mad, when I can just sail at my own leisure, all around the UK. If anyone told us we needed permission to float here they'd get told to fuck off 😆
I think you wouldn't have any problem if you brought your own boat over here. What you may not be able to do is rent one locally. Although I am certain many British tourists and residents do, so I don't know. You don't have any sort of piece of paper that says you "can" handle a boat, at all?
Nothing, I mean, they're available but not essential, I think they actually let Darwin have his way in at least one area of our lives
