Rules regarding alcohol on boats

The same rules which prohibit driving while impaired also apply to boats: you must not operate, assist to operate, or have the care and control of a vessel while impaired by alcohol or drugs.

Liquor must only be consumed in boats or other watercraft if the boat is licensed or it is a boat that the public does not have access to and is equipped with sleeping accommodations, cooking facilities and a toilet. In these cases, liquor may be consumed in the cabin or on the deck of the boat.
