Here is a little more detailed answer from NCL's FAQ's:

 

With the exception of Alaska and Hawaii itineraries, (Where you must be 21 years of age to consume or purchase alcohol of any kind) NCL permits guests between the ages of eighteen (18) and twenty (20) to purchase and personally consume wine and beer while on NCL ships with the consent of an accompanying parent or legal guardian on the same sailing once the vessel is outside the US state territorial waters (3 miles out). Complete details and special consent form are only available onboard at the Reception Desk.
