This model suits buyers who want a robust, configurable guide-on that minimizes hull contact damage and helps align the boat quickly on ramps. Caution: ensure the width adjustment is tightened to prevent rotation under load.
CE Smith – Trailer Pontoon Bunk Board Guide-On

Best for corrosion resistance and long life in marine environments. The guide-on uses galvanized steel with zinc-plated hardware for durability. It is designed to fit frames up to 3″ wide by 4-1/4″ tall, making it a fit for many trailer configurations. Rubber rollers provide minimal friction to guide pontoon boats smoothly onto the trailer. Ideal for boaters who need a reliable, maintenance-friendly option with straightforward installation. Limitation: may require precise frame sizing for optimal performance.
KUAFU Universal Boat Trailer Guide-On (24″-36″)

Best for bunk-style pontoon trailers with box, channel, or L-beam frames up to 3″ wide x 4-1/4″ tall.

The package includes two bunk boards with ready-to-install hardware and instructions. The guide-ons are made of sturdy steel and feature a simple mounting design. Choose this if you want a universal fit with easy setup, but beware of slightly taller installations requiring extra overhead clearance on low-clearance ramps.

This set is designed to help guide your pontoon quickly onto the trailer, reducing the effort required for loading.

This option is well-suited for occasional to moderate use where a compact, straightforward guide system is preferred. Caution: verify compatibility with your trailer frame height and crossbeam spacing before purchase.

It features carpeted boards to protect hulls and galvanized steel brackets for corrosion resistance. Height adjusts from approximately 13″ to 21″, making it versatile for ski, fishing, and sailboats.
