Like can I just jump in my boat and go? Do I have to alert any authority about my trip? What are the chances the coast guard boards my boat to search it? How do you find a marina in Mexico? Do I have to alert the Mexican government of my trip? I assume I need a passport.
This is to settle a very polite heated discussion between my partner and I. Where neither of us know what we’re talking about.
Awesome this along with skyketcher’s link seems to be the right answer.
I’ll admit that it’s slightly more involved than we thought it would be. My partner was of the opinion that the all knowing coast guard would swarm your boat as soon as you hit American waters. I figured it was more likely that if they see you they just come talk to you, but of course the answer is an app.
