If you could peel back the hull of a TRACKER^® boat, you'd see why they're so brawny and long lasting. Marine-grade aluminum forms the hull, longitudinal stringer system, compartment lids and the all-aluminum transom. Precision manufacturing equipment guarantees a consistent, tight fit. Internal support systems are designed to provide stiffness and rigidity. Pressurized foam, which provides maximum flotation that meets or exceeds U.S. Coast Guard requirements, is injected to reduce flexing and to improve rough water performance. Special tools and techniques, created by our master craftsmen, boost the strength and sturdiness of individual pieces and the welds that join them. Every all-welded hull on a TRACKER boat has a 5 year warranty from date of original purchase on the hull, transom and internal structure. See your local dealer for details.
