What to use to re floor your pontoon?

To re-floor your pontoon, you can use marine-grade plywood or composite decking materials, as they are designed to withstand moisture and resist rot. Marine-grade plywood is often treated for durability and can be covered with a non-slip marine carpet or vinyl for added safety and aesthetics. Ensure to use stainless steel screws and sealants to prevent water damage and corrosion. Additionally, consider installing a waterproof barrier beneath the flooring for added protection.
