Your boat is designed, licensed and insured for either four or six berths, depending on its size and no more than that number may sleep on board. If you turn up at the marina with five people or more for a four berth or 7 people or more for a six berth you will not be allowed to occupy the boat. This is not negotiable. Children, of whatever age - including babies - count as part of this complement. Please don't tell us that additional passengers will find alternative accommodation along the way, as others have been afforded this concession in the past and abused the privilege. It is therefore a firm rule that only the prescribed number (or less) will be allowed to take the boat.
