Boat Building with Composite Materials | Coosa Board | Sailboat & Trawler Restoration (Ep17)

In this episode of Motor City Boat Werks, Joe shows you step-by-step how to build custom boat cabinets using PVC foam board (Celtec/Komatex/Sintra). This ultra-practical material is waterproof, rot-proof, lightweight, and easy to work with, making it perfect for DIY boat restoration and marine cabinetry projects. I discuss Coroplast, Coosa Board, HDPE King Starboard, PVC Foam Board, Celtec, Komatex, Sintra, and Fiberglas G10. I also talk about building boat cabinets out of Celtec or PVC foam board using the Screw & Glue Method. This week I cover a Nav Pod and Refrigerator Stand Celtec boat building project. 00:00 Composite Materials 02:33 Coosa Board 04:18 PVC Foam Board 08:00 Cost 10:00 Construction Methods 11:46 Projects 15:00 Boat Works Today ⛵ WHAT THIS VIDEO COVERS ✅ What PVC foam board is and why it’s ideal for boat interiors ✅ Celtec vs Komatex vs Sintra — which PVC board to buy ✅ How to build marine cabinets using simple tools ✅ Screw-and-glue construction method explained ✅ Best epoxy for bonding PVC foam board ✅ How to pattern with cardboard or pink foam ✅How to mount cabinets without making them permanent ✅ Boat Furniture Examples: nav pod, refrigerator cabinet, aft cabin cowling If you're rebuilding a boat interior, cruising long-term, or looking for durable cabinets that won’t warp or rot, this video will teach you everything you need — from mockups and templates to epoxy bonding, shaping, and final installation. ⛵ FOLLOW THE FULL RESTORATION SERIES Watch the complete Albin 27 trawler rebuild — fiberglass work, epoxy tips, structural repairs, cabinetry, custom builds, and more. 🎥 Featured Projects & Playlists ➡️ Coosa Board & Composites    • Coosa Board and Composites For Boat Building   ➡️ Albin 27 Pocket Trawler Restoration    • Trawler Restoration | Albin 27 Family Crui...   ➡️ Skipper 20 Sailboat Rebuild    • Small Sailboat Restoration   ➡️ Small Sailboat Pilothouse    • How to Build a Small Sailboat Pilothouse   ⭐Join our community on Patreon for exclusive behind-the-scenes content, Technical Library articles, project plans, and boat restoration coaching: 🔗 Patreon.com/MotorCityBoatWerks 🔔MotorCity Boat Werks channel provides how-to tips and tricks for boat sailboat restoration and boat building.
