Since boats operate on public waterways, liquor may only be consumed in boats or other water craft if the vessel is licensed or it is being used as a residence. In this case, residents and their guests may consume liquor in the cabin or on the deck of their boat.
Having open liquor and drinking liquor in open vessels, small water craft, or vessels which are not equipped to be living quarters is not allowed.
Operating or assisting to operate a vessel or having the care and control of a vessel while impaired by alcohol or with a blood alcohol level more than .08 (eighty milligrams of alcohol in one hundred millilitres of blood) is a criminal offence. The same rules which prohibit driving while impaired apply to vessels.
Persons using smaller vessels for a special event, such as a day charter by a social club for its members, may obtain a Special Occasion Licence to allow for the sale and service of liquor to the participants.
Cruise ships and larger motor vessels that ply scheduled routes or travel from one destination to another may be licensed if they provide a service that, while primarily marine oriented, is consistent with the services provided by other sectors of the hospitality industry (for example, luncheon and dinner cruises).
