21ft Bumblebee Is almost finished!!

Okay, so many of you have been asking about the materials we're using for our 21ft Bumblebee, especially those sleek black structural components you've seen in our updates! Well, the secret ingredient is Coosa board, and let me tell you, it's been an absolute game-changer for this build. For those who aren't familiar, Coosa board isn't your typical plywood. It's a high-density, fiberglass-reinforced polyurethane foam panel. Think of it as a super-tough, super-lightweight composite material engineered specifically for marine and other demanding applications. It comes in different densities, and we opted for one that gives us incredible strength without adding unnecessary weight. When we started planning the 21ft Bumblebee, durability and longevity were top priorities. Traditional marine plywood, while good, can eventually succumb to rot and water damage if not perfectly sealed and maintained. Coosa board, on the other hand, is completely rot-proof. It doesn't absorb water, so we don't have to worry about delamination or fungal growth – a huge relief, especially for a boat that's going to see a lot of action on the water. Plus, it's incredibly stable and resists warping, which is crucial for structural integrity. Working with Coosa board has been surprisingly easy. It cuts beautifully with standard woodworking tools, which made shaping those intricate structural components a breeze. You can also bond and fasten to it just like wood, but with the added peace of mind that it won't degrade over time. We've used it for the inner hull structure, creating those strong black panels you've seen, and it gives the boat a really robust, almost factory-finished look even before we've added the final layers. Seeing how neatly these panels fit into the framework has been incredibly satisfying. Right now, we're laying down the wooden strips that will support our level floors, and underneath, you bet we're considering more Coosa board for the decking. Its excellent screw retention and ability to withstand constant moisture make it ideal for areas that get a lot of foot traffic and exposure. It’s definitely an investment, but for a boat we plan to enjoy for years, it’s worth every penny. If you're thinking about building or renovating a boat, or even tackling an RV project where moisture resistance and weight are factors, I highly recommend looking into Coosa board. It's a premium material, but the peace of mind and performance it offers are unparalleled. We're so close to finishing our 21ft Bumblebee, and knowing it's built with such high-quality, durable materials like Coosa board makes us even more excited for its maiden voyage!
