The boards measure 24″ x 4″ x 2″ with carpet coverage to protect hull surfaces. The frame height is 21 inches with 13-inch adjustable arms on each side, offering flexible mounting for smaller boats.

Two 6-foot carpeted bunks provide longer support for mid-to-large boats on longer trailers. Best for owners seeking uniform bunk length for consistent hull support. Drill-ready and simple to install, with standard packaging and dimensions suitable for many trailers. Limitation: not ideal for ultra-short trailers where bunk length may extend beyond the frame.

Two 8-foot carpeted bunk boards suit longer trailers and boats, with a default size of 1.5″ x 3.5″ x 96″ boards. These are a strong option for extended bunk support, offering durable carpet protection and broad hull contact. Consideration: ensure your trailer can accommodate the 8-foot length without interference on the frame or winch area.

Two carpeted bunk boards designed for easy loading and hull protection. They use marine-grade lumber with soft carpet to cushion impacts and minimize hull scratches. Best for budget-conscious buyers seeking reliable protection with straightforward installation.

Two 4-foot bunk boards provide a sturdy option for mid-length trailers and versatile mounting. They feature soft carpet and marine-grade lumber for hull protection. Choice for those who want longer bunks without moving into the full 8-foot range. Limitation: ensure the 4-foot length aligns with your trailer bed width and mounting hardware.
Buying Guide
Key considerations when choosing bunker boards for boat trailers include: bunk size and trailer compatibility, hull protection level, installation ease, and environmental durability. If you have a short or narrow trailer, prioritize 24″ boards with adjustable frames. For longer trailers, consider 6–8 foot bunks to maximize hull support. Carpeting should be marine-grade to resist saltwater and UV exposure, and frames should be galvanized or similarly rust-resistant for longevity. Always measure your trailer frame before buying to confirm fit, especially frame width, height, and mounting options. Consider whether you need tilting designs for easier loading or center-aligning guides to keep boats perfectly centered during docking.
