Open Alcohol on Boats in Arizona: Illegal

No. Arizona law (ARS § 4-244, § 5-395) prohibits open containers of alcohol on any watercraft—boats, sailboats, yachts, jet skis, rafts—on all state waters.

• Applies to operators and passengers.
• "Open container" = any bottle/can/cup with broken seal or partial contents.
• Penalties: Class 1 misdemeanor (up to 6 months jail, $2,500 fine); enhanced if OUI (Operating Under Influence).
• Exception: Licensed commercial vessels with onboard liquor license (rare).

Arizona also enforces OUI laws (BAC ≥ 0.08%) strictly. Designate a sober captain; keep alcohol sealed until ashore.
