Build-A-Boat comes with 10 colorful pieces that allow you to build a fireboat, tug boat, freighter, oil tanker, fishing boat or the boat of your dreams. The secret lies in our hidden magnetic locking system that makes both assembly and disassembly a snap. Once you've built your boat, you're ready to launch her in your bathtub, sink, or swimming pool. Our waterproof hull guarantees a safe voyage and hidden wheels make her easy to push for those who are landlocked. We call it creativity on the high seas!
