Can You Use Trex for Boat Trailer Bunks

If you have a boat, you need a place to keep it when you’re not using it. Most people have a dock or a boathouse, but if you don’t have either of those, you’ll need to trailer your boat to and from the launch ramp. Trex is a popular brand of composite decking material, and some people wonder if it can be used for boat trailer bunks.

The answer is yes, but there are a few things to keep in mind.

  • If your boat trailer has existing bunks, you can use these as a guide to install Trex boards
  • Otherwise, you’ll need to measure and mark where you want the Trex boards to be installed
  • Cut the Trex boards to size using a power saw
  • Apply marine-grade adhesive to the back of each board and then affix them in place on the trailer bunks
  • Use clamps or heavy weights to hold the boards in place while the adhesive dries overnight
  • Once dry, your new Trex boat trailer bunks will be ready for use!

Can Trex Be Used for Trailer Decking?

You betcha! In fact, Trex is one of the most popular choices for trailer decking. Its main advantages are that it’s incredibly durable (it’s made from recycled plastic and wood fibers, so it’s built to last), and it requires very little maintenance.

Plus, it comes in a variety of colors and styles to suit any taste.

What is the Best Wood to Use for Boat Trailer Bunks?

If you’re looking for the best wood to use for boat trailer bunks, you’ll want to consider a few factors. First, you’ll need to decide if you want hardwood or softwood. Hardwoods are more durable and typically last longer, while softwoods are more affordable.

You’ll also need to decide what kind of wood is best suited for your climate. In general, cedar and Douglas fir are good choices for boat trailer bunks. Cedar is a popular choice for boat trailer bunks because it’s lightweight and rot-resistant.

It’s also easy to work with and takes stain and paint well. Douglas fir is another good option because it’s strong and has a high weight-to-strength ratio. It’s important to note that both cedar and Douglas fir will weather over time if left untreated.

If you plan on leaving your boat trailer bunks outside, you may want to consider treating them with a sealant or waterproofing agent. When choosing the best wood for your boat trailer bunks, it’s important to consider both function and aesthetics. The type of wood you choose should be able to withstand the elements and stand up to wear and tear from loading and unloading boats.

At the same time, you’ll want something that looks good and complements the aesthetic of your trailer. With so many options available, taking some time to research different woods before making a final decision is worth the effort.

Can You Use Treated Wood on Boat Trailer?

You can use treated wood on boat trailers in most cases, but there are a few things to keep in mind. First, treated wood is typically more expensive than regular lumber, so it may not be the best choice if you’re on a budget. Second, treated wood is often heavier and harder to work with than regular lumber, so it’s important to consider how much time and effort you’re willing to put into building or repairing your trailer.

Third, some types of treated wood contain chemicals that could be harmful to your boat or trailer if they come into contact with them, so it’s important to check with the manufacturer before using any treated lumber. Finally, always follow the manufacturer’s instructions for working with treated lumber to ensure the safest and most effective results.

How Long Should Bunk Boards Be on a Boat Trailer?

There is no definitive answer to this question as it depends on a number of factors, including the size and weight of your boat, the type of trailer you have, and the roads and conditions you’ll be driving in. However, as a general rule of thumb, most experts recommend that bunk boards should be at least 8 feet long for boats up to 20 feet long, and 10 feet long for boats over 20 feet. Of course, it’s always best to consult with your trailer manufacturer or dealer to get specific advice for your situation.

And when in doubt, err on the side of caution – it’s better to have too much board than not enough!

Making Boat Bunk Using Plastic Lumber (Part 1 of 2)

Composite Boat Trailer Bunks

Boat trailers are designed to get your vessel from point A to point B with as little drama as possible. However, one of the most common issues boat owners face is hull damage caused by rubbing against trailer bunks during transit. This can be a particular problem if you frequently trailer your boat over long distances, or if you often encounter rough roads or potholes.

One solution to this problem is to switch from traditional wooden bunks to composite ones. Composite bunks are made from durable plastic materials that will not damage your hull, no matter how much friction is generated during transit. In addition, they are also typically wider than wooden bunks, which helps distribute the weight of your boat more evenly and prevents indentations from forming in the hull.

If you’re looking for a way to protect your investment and keep your boat in good shape for years to come, consider switching to composite boat trailer bunks. You’ll be glad you did!


If you’re in the market for a new boat trailer, you may be wondering if Trex is a good material to use for the bunks. Trex is a synthetic lumber made from recycled plastic and wood fiber. It’s an attractive and durable alternative to traditional wood lumber, and it’s also eco-friendly.

But is it suitable for boat trailer bunks? Here’s what you need to know about using Trex for boat trailer bunks: Trex is rot-resistant and splinter-free, so it’s ideal for use in wet environments like boat trailers.
