Carpeted BUNK Board 6′ 2PK

Best for lightweight-to-moderate loads and quick swaps, the Carpeted BUNK Board 6′ 2PK from SMITH provides a simple, affordable way to refresh trailer bunks. The package includes two boards, each sized for typical 6-foot trailer frames. While wood-backed bunks with carpet are easy to cut and install, they require periodic inspection for wear and moisture exposure. This option is well suited for occasional trailer use, smaller boats, or quick roadside upgrades.
Who this is for: boaters needing a budget-friendly, simple install that maintains hull protection without specialized hardware. Why chosen: compact length and dual-pack convenience make it ideal for smaller trailers or as a starter replacement set. Caution: wood bunks can absorb moisture over time; check for loosening screws and turf wear after salt use.
(2) 8′ Long Marine Carpet Black Bunk Boards – 2×4

This set offers two 8-foot carpeted bunk boards sized at 1.5″x3.5″x96″ (2x4x8). The fabric is UV-stabilized polypropylene nonwoven, designed to stand up to sunlight and water exposure. Best for: trailers with longer bunks or wider hulls that require steady hull support along a longer surface. Limitation: carpet and fabric wear over time with heavy use or rough road conditions, so inspect for fraying periodically.
(2) 8′ Black PermaBunk Boards – Marine Trailer Runners – 2×4

Best for durability and rot resistance, these 8′ PermaBunk boards are made from recycled HDPE. They will not rot, fuzz, zipper, or unravel, and they resist moisture, mold, and mildew. This makes them suitable for frequent or saltwater use. Choose this if you want a long-term, low-maintenance bunk solution. Caution: HDPE boards can be stiffer than carpeted boards, so ensure proper fit and alignment to prevent hull contact with hard surfaces.
Desunqin 2 Pack Carpeted Marine Boat Trailer Bunks

Desunqin offers a 2-pack of carpeted bunk boards designed to protect boats from scratches while providing extra trailer support. Each bunk is sized for easy handling and installation, with marine-grade wood built for repeated use. Best for: budget-conscious buyers seeking straightforward, carpeted support that fits common trailer frames. Limitation: verify size compatibility before purchase to ensure fit with your trailer’s bunks.
(2) 8′ Long Marine Carpet BLACK Bunk Boards w/PADDING

These bunk boards combine carpet with HD padding underneath to cushion the hull. The boards measure 1.5″x3.5″x96″ (2x4x8), matching standard trailer frames. Best for boats that require extra load distribution and hull protection. Choose this if you want a softer landing and reduced hull impact. Caution: padding can trap moisture if not properly ventilated; inspect for wear and replace when padding compresses.
Buying Guide
What material should you choose for bunk boards?
- Carpeted wood bunks are affordable and easy to install but can rot without proper maintenance. Best for light to moderate use and frequent hull protection at a lower cost.
- HDPE or PermaBunk boards offer rot resistance and low maintenance, ideal for frequent or saltwater use. They are longer-lasting but may require different mounting hardware or alignment checks.
Which length is right for your trailer?
- 8-foot boards provide longer contact surfaces, better support for wider hulls, and are common on longer trailers. They reduce point load but may require more drilling space.
- 6-foot boards work well on shorter or narrower trailers, offering a quick replacement option for smaller boats or DIY projects.
What about padding and protection?
- Boards with padding under carpet can cushion hull contact and reduce wear, particularly for lighter boats or surfaces that bounce on the road.
- Padding can trap moisture if not ventilated; ensure proper drainage and periodic drying during storage.
How to install and maintain bunk boards?
- Confirm the mounting pattern and screw types compatible with your trailer. Pre-drill holes to prevent splitting, especially on wood versions.
- Inspect for wear, rot, and carpet fray after exposure to road salt, frequent launches, and heavy use. Replace boards showing significant wear to protect the hull.

FAQ

- Do bunk boards require special hardware?
- Can bunk boards be cut to fit a non-standard trailer?

Lifetime varies by material and use. HDPE PermaBunk boards generally offer longer service with less maintenance than carpeted wood boards, especially in salty or humid environments.
Installation usually uses standard trailer hardware, but some boards may require different screw patterns or brackets. Confirm fit before buying.
Yes, many bunk boards can be trimmed for a custom fit. Use a saw appropriate for the material and recheck alignment after cutting.
Clean the carpet periodically, check for fraying, and inspect for moisture build-up. Replace if padding or carpet shows significant wear.
Rot-resistant options reduce maintenance and increase lifespan, especially on boats stored near saltwater or in damp climates.
