What is a Double Keel Roller Assembly?
A Double Keel Roller Assembly is a trailer part designed to support and guide the keel of a boat. The keel is the central structural line along the boat’s bottom. This assembly uses two rollers instead of one, offering greater stability and even weight distribution. It protects the hull during transport, especially for heavier or larger boats.
Key Components and Materials
The assembly includes two rollers, typically made of rubber or polyurethane. Rubber rollers are softer and ideal for aluminum boats. Polyurethane rollers are harder and more durable, making them better for fiberglass boats and saltwater use. The rollers spin freely on a steel shaft, which helps reduce friction. This allows the boat to glide smoothly during loading or unloading. The bracket holding the rollers is made of galvanized or stainless steel. It resists rust and can often be adjusted to fit the boat’s hull shape.
Functionality and Benefits
A Double Keel Roller Assembly supports the keel evenly, reducing stress on the boat’s hull. It also helps center the boat on the trailer, improving safety and control. This is especially helpful in strong wind or current. The rollers guide the boat straight onto the trailer, making loading and unloading quicker and easier. This reduces effort and minimizes the risk of misalignment or hull damage.
Installation and Maintenance
Installing a Double Keel Roller Assembly is simple. The bracket attaches to the trailer frame using U-bolts or similar hardware. The roller height can then be adjusted for best contact with the keel. Maintenance is minimal. Check the rollers and bolts regularly for wear, rust, or looseness. If needed, parts are easy to replace. With proper care, the assembly will last for years and help keep your boat safe.
