Sprenger Keel Rollers are used on boat trailers to support and guide the keel (bottom centerline) of the boat during loading, unloading, and transportation. Their main functions include:
1. Supporting the Boat’s Weight: They help distribute the boat’s weight evenly across the trailer, reducing stress on the hull and maintaining balance during transport.
2. Guiding the Boat During Loading and Unloading: The rollers help center the boat on the trailer, ensuring it stays aligned as it is pulled in or pushed out of the water.
3. Protecting the Boat’s Keel: By providing a cushioned surface, they prevent scratches, dents, and other damage to the keel.
4. Easing Launch and Retrieval: The rolling action minimizes friction, making it easier to slide the boat on and off the trailer.
5. Reducing Wear and Tear: The rubber or polyurethane construction is designed to be durable and weather-resistant, ensuring a long lifespan even in harsh marine conditions.
They are typically installed along the centerline of the trailer and are commonly used with powerboats, sailboats, and other vessels that require reliable keel support.
