Large Boat Trailers

GFAB Alloy Trailers built for large boats

Best suited for boats weighing between 2501-3500kg on their trailer.

All GFAB Alloy boat trailers, are designed & built specifically to suit your boat’s make and model, taking into account any features that make your boat unique.

Our large boat trailers are either tandem or triple axled and rated to 3500kg and they are best suited for boats between 7.5-9m

With a rating of up to 3500kg, these trailers come fitted with an electric hydraulic braking system which is either connected to the vehicle through a hardwired system if fitted, or with a Credo Unit that has wireless in-cab control for total control over your trailer.

Backed by a 12 year chassis warranty, you can be confident that your trailer has been built to last.

GFAB’s boat trailers are all fabricated with care by our team of legends which gives GFAB trailers their strength and good looks. 

We know that reliability is essential when owning a trailer, which is why we choose to only use the New Zealand designed UniHub system on all of our marine trailers. UniHubs are a fully enclosed bearing system that means worrying about re-greasing your bearings is a thing of the past.


  • Chassis is made from C Sections of 6mm Marine Grade, High Tensile Aluminium
  • 13 Inch Black Alloys with high capacity tyres
  • Keel rollers down the centre of the trailer to support most of the boat’s weight
  • Plastic bunks on trailers for alloy boats - Roller bunks for fibre-glass or timber boats
