Understand the Basics: Roller Trailers vs. Bunk Trailers

Boat trailers come in two main types: roller trailers and bunk trailers. Each has its strengths, depending on where you launch and what type of boat you have.

• Roller Trailers: Ideal for shallow ramps, these trailers allow you to roll the boat on and off with minimal backing into the water. They’re perfect if you’re launching in places with lower water levels.
• Bunk Trailers: These use fixed bunks (supports) to cradle the boat. They work well with deeper ramps and provide a bit more stability for the boat, especially during transit. Bunk trailers tend to be more affordable and are generally easier on aluminium hulls.

For those who want the best of both, roller bunk trailers combine elements of both types, offering support and easy launching.

Upgrade to Better Parts for Longevity

Many stock trailers come with basic parts, but investing in high-quality boat trailer parts can improve your trailer’s performance and protect your boat. Consider the following upgrades:

• HDPE or Polyurethane Rollers: These materials are less likely to crack or split than rubber, offering smoother support and preventing damage to your boat’s hull.
• Sturdy Winches and Jockey Wheels: Quality winches make loading and unloading easier, while strong jockey wheels improve stability when maneuvering your trailer.
• Durable Skids and Bunks: Look for corrosion-resistant skids or bunk covers for extra protection, especially if you use your trailer in saltwater.

At Trailer Spare Parts Australia, we provide a wide range of trailer parts and accessories that enhance durability, protect your boat, and simplify maintenance.

Choose the Right Material: Steel or Aluminium?

Boat trailers are typically made from galvanised steel or aluminium, and each has its pros and cons:

• Galvanised Steel: Strong and rust-resistant, but not rust-proof. It’s a great choice if durability is your priority and you want a trailer that can handle rougher conditions.
• Aluminium: Lightweight and corrosion-resistant, making it ideal for saltwater environments. However, aluminium trailers may flex more, which some boaters find concerning for larger boats.

Regardless of the material, always rinse your trailer with fresh water after each use to extend its lifespan, especially if you’re launching in saltwater.

Match the Trailer to Your Boat’s Size and Weight

Ensuring your trailer can handle your boat’s size and weight is critical for safety. A trailer with the right load rating prevents excessive wear and keeps your boat securely in place.

• Load Capacity: Check your boat’s weight, including fuel and gear, and make sure the trailer’s capacity exceeds this. An overloaded trailer isn’t just a hassle—it’s a serious safety risk.
• Boat Length: Trailers are also designed for different boat lengths, so measure your boat accurately. A trailer too short or too long can make launching and towing more difficult.

Consider the Axles: Single or Tandem?

The right axle setup can make a big difference, especially if you’re towing a larger boat. Single axle trailers are lighter, easier to manoeuvre, and have lower maintenance costs. However, if you have a larger, heavier boat, a tandem axle trailer provides more stability and a smoother ride on the highway.

Think About Your Launch Site and Routine

Consider where you typically launch your boat. If you frequently visit shallow ramps, a roller trailer will make things easier. If you use deeper ramps or travel longer distances, a bunk trailer might be the better choice for added stability on the road.
