The roller's TPU construction resists corrosion, avoids marking gelcoat, and cushions hull contact during launching and towing. With a 5-inch overall width, it's engineered to keep the boat aligned and absorb road shock while preventing bolts or metal edges from scraping the hull.\u003c\/p\u003e\n\n\u003ch3\u003eHow does this roller protect my boat during launch and retrieval?\u003c\/h3\u003e\n\u003cp\u003eThe soft-but-resilient TPU surface reduces direct metal-to-hull contact, so the bow slides smoothly when launching or loading.
