About CPI Marine

Our manufacturing and quality processes are rigorous. Our design and manufacturing experts can create new designs to meet the boat builders specific requirements using a state of the art CAD/CAM system, or can reference the hundreds of patterns already on file. Each collar is accurately cut out by computer-controlled cutting table, ensuring a perfect fit every time. Every product is pressure tested for 24 hours prior to delivery to ensure no pressure loss. All products come with a one year parts and fabric warranty.
