American Pontoon is the premier custom work platform builder. We have built and designed hundreds of custom platforms. We can build them from the ground up or retrofit your existing platform. We are a certified USCG-compliant shop. We have worked closely with the USCG for our customers to insure that their vessel is in compliance. We have large diameters available, up to 36 inches. Our commercial-style tube is sectioned and bulkheaded every 5 feet. Included are inspection ports and the side and bottom keel. References are available upon request.
