Can You Use Pressure Treated Wood for Boat Bunks

Most boat owners will tell you that pressure treated wood is not the best choice for boat bunks. The main reason for this is that the chemicals in pressure treated wood can be harmful to marine life. There are also concerns about the long-term effects of these chemicals on humans.

However, some experts argue that pressure treated wood is safe for use in boats, as long as it is properly sealed.

  • Decide on the size and shape of your boat bunks
  • Pressure treated wood is available in a variety of sizes and shapes at most home improvement stores
  • Cut the pressure treated wood to size using a saw
  • If you are not experienced in using a saw, it may be best to have someone else do this for you
  • Drill holes in the pressure treated wood for any bolts or screws that will be used to attach it to the boat hull
  • Be sure to drill these holes slightly larger than the bolts or screws that will be used so that they can be easily inserted and removed
  • Attach the pressure treated wood to the boat hull using bolts or screws, making sure that they are securely tightened in place

Is Pressure Treated Wood Good for Boat Trailers?

If you’re looking for an affordable and durable option for your boat trailer, pressure treated wood may be the way to go. Pressure treated lumber is infused with chemicals that make it resistant to rot, insect damage and decay, so it can withstand the elements much better than regular wood. It’s also cheaper than aluminum or composite materials.

However, there are some drawbacks to using pressure treated wood for your boat trailer. The chemicals used to treat the lumber can be harmful to the environment, and they may leach out into the water if the trailer comes into contact with it. Additionally, pressure treated wood is not as strong as other options like aluminum, so it may not be able to handle heavy loads as well.

How Long Should Bunk Boards Be on a Boat Trailer?

The length of the bunk boards on a boat trailer is determined by the size and weight of the boat. For smaller boats, the bunk boards should be shorter so that they do not extend past the width of the trailer. Heavier boats will require longer bunk boards to provide support for the entire length of the hull.

The bottom line is to make sure that your bunk boards are long enough to properly support your boat without extending too far past the sides of the trailer.

How Do You Make a Boat Bunk Board?

Assuming you would like a tutorial on how to make a boat bunk board: What You’ll Need: -1/2″ marine plywood

-1×4 boards (8′) -wood screws (#8 x 2″) -staple gun & staples

-ruler or measuring tape -saw (jigsaw, hand saw, or circular) Tools:

-(optional) drill Instructions: 1. Begin by measuring and cutting your marine plywood to the desired size of your bunk board.

Ours was cut to 80″x24″. You will want to use a straight edge and clamps when cutting if you have them available. If not, a good steady hand will work just fine.

Jigsaws are great for curves, but if you don’t have one available a handsaw or circular saw will work for this project as well. Just be extra careful when making your cuts so that they are as accurate as possible! 2. Once the main piece is cut, it’s time to move on to the 1×4’s.

These will be used as trim around the edges of the plywood, and also serve as support for whatever mattress or foam cushion you plan on using. Cut these pieces down to size – ours were 24″ long each – and then use wood glue and screws (we used 2″ screws) to attach them around the perimeter of the plywood. Make sure everything is nice and level before moving on! 3. Now it’s time for the fun part – adding fabric! This step is completely optional, but we decided to add a little bit of personality to our bunk board by wrapping it in fabric first. We simply laid out our fabric wrong side up on the ground, placed the plywood piece on top, pulled it tight and stapled it into place with our staple gun every few inches around all four sides. Be sure to pull tight so there aren’t any wrinkles or bunching in the fabric! 4. And that’s it!

Is Douglas Fir Good for Trailer Bunks?

Douglas fir is an excellent wood for trailer bunks because it is strong and durable. It is also rot resistant, making it ideal for use in wet or humid conditions. Douglas fir is also relatively lightweight, making it easy to handle and install.


Treated Or Untreated Wood for Trailer Bunks

If you’re looking to replace the wood on your trailer bunks, you may be wondering if you should use treated or untreated wood. Here’s a look at the pros and cons of each option to help you decide which is right for you. Treated Wood

Pros: Treated wood is designed to resist rot and decay, so it will last longer than untreated wood. It’s also less likely to warp or crack over time. Cons: Treated wood is more expensive than untreated wood.

It can also be more difficult to find in some areas. And because it’s treated with chemicals, it may not be the best choice if you’re concerned about the environment. Untreated Wood

Pros: Untreated wood is less expensive than treated wood and easier to find. And because it hasn’t been treated with chemicals, it’s a better choice for the environment. Cons: Untreated wood isn’t as resistant to rot and decay as treated wood, so it won’t last as long.


Yes, you can use pressure treated wood for boat bunks. The pressure treated wood will last longer and be more resistant to rot and decay.
