Hello, want to move to Spain.?

I don't live in Spain, but I can tell you right now that it isn't warm all year round. Spain isn't close enough to the equator for that. If you are from the US, it shouldn't be hard at all to get a resident's visa, which last for years at a time. As for living on the ocean, be sure that it is going to be very expensive, just like anywhere else in the world.
