At Novamar "It's About You, Our Client"
We would like to remind you that you are required to have a boating license while you are navigating your boat in Mexican waters. Every boat owner, operator, and captain at the helm of a vessel must have a valid boating license that states you are qualified to operate the vessel. If you have a foreign flagged vessel in Mexican waters then you must have the proper operating license issued by the state or country where you registered your vessel. EVEN IF A BOATING LICENSE IS NOT REQUIRED IN YOUR HOME COUNTRY.
Mexican citizens operating vessels in Mexican waters must have a “Libreta de Mar” license issued by the Mexican government’s Secretaría de Marina through its Unidad de Capitanías de Puerto y Asuntos Marítimos (UNICAPAM).
The Mexican authorities will likely ask for a copy of a boating license if you are involved in an accident aboard your boat. Plus the Mexican insurance companies require this license in order to pay claims.
