Children have fun on the boat at any age, the only question is what effort needs to be made to ensure their safety. Children between 8 months and 2 years need a personal babysitter when they are awake and the boat is moving. If a child can already understand and follow the first rules, one person should still keep an eye on the toddler. Make sure that children wear life jackets that are suitable for their size and weight as soon as they are on deck.
