Boats in this section that are identified as 'Sailing' are made for play in water. Each is carefully tested for the appropriate use and are listed in a category based on your play needs. You can always “down grade” and use a more serious boat in calmer conditions. (As an example you can use a Pond boat in a pond, or in a pool or a tub. Just nothing larger than a Pond.) Boats labeled for ground play cannot be used in water.
