Due to the non-skid surface on our vessels, being barefoot provides you the best natural grip, in addition to keeping our decks nice and clean. The captain may make an exception if you have a medical condition that requires you to keep your footwear on. Please mention this at booking time or when you check-in so you can speak with the captain, as it’s a case-by-case basis. In cases where someone keeps their shoes on, it may be requested that you stay seated for most of the tour. We will collect your footwear just before boarding the vessel and they will be returned immediately after disembarking.
