Haba Terra Kids Cork Boat Kit. Easy to put together kit. Anchors aweigh, and it’s ship ahoy! This boat takes only a short time to put together before it is ready to sail into uncharted waters in any weather. It consists of compressed cork granules and is thus virtually unsinkable. Ideal for a weekend trip to the water or a family holiday on the beach. Young boat builders can upgrade this cork vessel with elements they find lying around in nature to make a sail. There are some great suggestions for this in the enclosed instructions. Made of natural materials with optimum floating properties. For use in shallow water, sea or bath tub.
