The boundary line referred to in the CFR's for a near-coastal license is 12mi for the Gulf of Mexico, It is NOT 3 MILES. This is the link for the Coast Guard Policy letter refering to boundaryintheGOM:

100 ton Licenses have specific minimum sea-service tonnage requirements, 6 pack licenses have no tonnage requirements, and 100 ton Licenses require twice the sea-time of the 6-pack license. You guys offering advice on stuff without the factscould really screw people up.I would recommend anyone needing info on licensing contact a reputable training school like Passport Marine in Pensacola or contact theCoast Guard NMC directly. Advice online should always be taken with a grain of salt. Hope this helps, best of luck guys. Later.
