Factors to Consider When Buying a Boat Trailer

Quality trailers do all the heavy work of transporting, launching, and storing your boats. The best-designed and manufactured trailers can do all these tasks without issues. Boat trailers for sale in NZ follow similar standards and expectations, which is important as Kiwis love recreational boating and other water-based activities.

This article is for boating beginners on the hunt for your first trailer. Below is a list of the features to look at before closing the deal on a boat trailer.

Features to Check When Purchasing a Trailer for Your Boat

Consider these factors before buying your first boat trailer.

Boat Type

For starters, your choice of a trailer should depend on the kind of boat you have. This factor will determine the required dimensions. Small boat trailers can accommodate boats and watercrafts under 20 feet and 3,600 pounds. Longer vessels within 21 to 36 feet, exceeding 5,200 pounds, will naturally require large boat trailers.

Most importantly, check the trailer’s gross vehicle weight rating or GVWR. This rating will determine the total amount of weight your trailer can carry. Ensure your chosen option can hold 15% more than your boat needs.


The type and size of your boat will also determine if you need a single or multi-axle trailer. Smaller trailers have a two-wheel and single-axle mechanism. This axle type also allows convenient manoeuvrability and is much easier to maintain. Multi-axle boats are for large trailers to meet the weight and dimensions demand. While they are harder to control, require more maintenance, and are more expensive, they are safer and more stable.

Trailer Regulations

Before buying a trailer, make sure that you’re looking at models that fit your country’s trailer regulations. 

The standard rule is to use trailers equipped with turn signals and working brakes. These features are not just accessories. They are essential components to ensure road safety and manoeuvrability. The requirements may also vary depending on the trailer’s dimensions.

Materials and Coating

Your boat’s trailer should withstand harsh elements. Make sure that it is built to last, with the best materials in the market today: aluminium, steel, and composites. 

Steel and aluminium trailers are ideal for freshwater boating. However, they are vulnerable to corrosion and rust when used in saltwater. A trailer made of galvanised steel will solve this problem. Composites, on the other hand, offer lightweight, sturdy, and corrosion-resistant qualities. 

Condition and Performance

Finally, check your chosen trailer’s overall condition and performance of your boat trailer, especially if you are buying used or having it customised. 

Before making the big purchase, search the frame for rust, corrosion, or misalignment. Test the brakes. You should also test the springs and tyres, especially if transporting through uneven terrain. Lastly, check the wiring and lights to ensure they’re working and ready for the road.

That is everything you should know before buying a boat trailer for sale in NZ. Hopefully, these factors will help you purchase a trailer that meets all your needs.
