The vessels are returned to the base on Friday afternoon/evening with an overnight on board till Saturday morning between 8am and 9am, when the check-out procedure is done. At that time the guests should leave the boat, so that it can be cleaned and prepared for new guests. The vessel can also be returned to the base on Saturday, but make sure it is before 8am, in order for guests to have enough time to fill the tank before leaving the vessel.
