DIY Boat Trailer Bunk Brackets: Crafting Your Own

Before we delve into whether making your own boat trailer bunk brackets is worth it, let’s first discuss how you can create them. Fortunately, boat trailer bunk brackets are relatively simple to make, consisting of just a few components. Here’s what you’ll need:


  • Several 6″ or 8″ long 2×4 pieces of wood
  • Black outdoor rug or marine fabric
  • Staple gun with stainless steel staples
  • Metal mounting brackets (vertical mount brackets, swivel top bunk brackets, or pontoon boat bunk brackets, depending on your preference)


  1. Determine the number of bunk brackets you need. Most trailers have 4 to 8 bunk brackets, measuring 6″ to 8″ in length. If you’re replacing existing brackets, count them and measure the appropriate lengths.
  2. Cut the wood pieces to the desired size. Buying a long 2×4″ piece of wood and using a chop saw for quick cuts is recommended. Cedar or the most affordable wood at your local hardware store can be used.
  3. Measure a square piece of carpet that fully covers each piece of wood, folding it up on the underside. If you’re replacing old brackets with carpet, you can use the old pieces as templates.
  4. Wrap the carpet tightly around the wood and use a nail gun to secure it. Nail the loose ends to the bottom of the board to ensure a flat top surface and prevent any potential damage to your boat’s keel or keel guard.
  5. Attach the covered wooden boards to your trailer using the selected brackets. Consider mounting them in a similar location to the old brackets.
  6. That’s it! You’ve successfully made your own boat trailer bunk brackets.

Now that you know how to make your own bunk brackets, let’s weigh the pros and cons of going the DIY route. This analysis will help you determine if investing your time and effort is worthwhile.

Pros of DIY Boat Trailer Bunk Brackets

  • Cost-effectiveness: By purchasing wood, carpet, and brackets separately, you’ll often spend less than buying premade brackets. Making and attaching your own brackets can save you a couple of hundred dollars, especially when factoring in installation costs.
  • Enjoyable activity: If you relish the opportunity to unleash your creativity and work with tools, DIY boat trailer bunk brackets can be an engaging project. It’s an excellent activity to work on alone or involve younger boaters as a fun learning experience.
  • Customizability: Need a bunk bracket of a specific length that’s not readily available at marine shops? No problem! The beauty of building your own is the ability to customize the dimensions according to your exact requirements.

Cons of DIY Boat Trailer Bunk Brackets

  • Affordability: Premade boat trailer bunk brackets are already quite inexpensive, with prices often hovering around $50, depending on the size. If the cost difference between DIY and premade brackets is only $20 to $30, it might not be worth investing your time and effort.
  • Crucial component: Bunk brackets play a vital role in safely transporting your boat. If a bracket were to break or come loose, the consequences could be catastrophic, potentially causing significant damage to your boat or posing risks to others around you.
  • Time-consuming: Considering the time spent making a relatively straightforward product that can be readily purchased, it’s worth questioning whether your time is better allocated elsewhere.

After evaluating the pros and cons of making your own boat trailer brackets, our general recommendation is that, for most people, DIY may not be the best choice. Opting for premade boat brackets and either installing them yourself or seeking professional assistance tends to be a more sensible approach.

Considering the critical role that bunk brackets play in ensuring your boat’s safe transportation, it’s better not to risk potential errors. Moreover, given the minimal price difference between premade and DIY options, it’s often more cost-effective to purchase them from reputable suppliers.

The last thing you’d want is for your expensive jet boat or reliable salmon fishing vessel to slide off the trailer and sustain hull or offshore bracket damage. However, if you enjoy DIY projects, don’t hesitate to explore our guide to aftermarket leaning posts.
