the only licensure i know of for boats that mexico had was the fishing
licensure--conapesca will answer your questions. you HAVE to have one of these BEFORE you bring fishing equipment
into mexican waters. they take poaching very very seriously--and it takes 6 months to get the license online--san diego downtown is the only place to get these in the usa. if you know anyone who lives there / here, then send them to get it for you so it only takes 5 min.. look up conapesca online and see the current fees
. mine were nearly 100dollars for 2 people for one year.. each crew member
needs one. no longer needed for boat or dinks,. as used to be the case.
other than that--i know of no licensure required for mexican waters and i have been boarded by the mexican navy
in their waters--this is to be expected, they will look for fishing equipment
and drugs and firearms. bring none of those. this will be reinforced in downwind marine's cruiser guide for the baja
haha and southbound sailors....
