Of course you can drink alcohol on board. However, we would like to remind you that the risks are greater on the water than on land. Moreover, alcohol increases the risk of seasickness. Therefore, we strongly advise you: drink in moderation!
In certain weather conditions, the skipper or captain may ask the group not to drink alcohol. This is done only if it is essential for the safety of the guests. This request, in the interest of your own safety, must be followed.
On some ships, alcohol is allowed only when the ship is in port or at anchor.
