GP Engineering trailers are designed and built in New Zealand. Engineering expertise, innovative concepts and high-quality components ensure our boat and jetski trailers are superior to all others.

Trailers for Wavebreak RHIBs


Standard Skids or Multi-Roller Options

Our dipped galvanized steel trailers come standard with skids which are recommended for inclined launch sites and ramps. For flat launching areas we recommend installing multi-rollers.

Ultimate Hull Support

Unlike "cookie-cutter" mass produced products GP Engineering trailers are designed to complement the Wavebreak, providing superior support to the boat's hull while ensuring smooth towing and easy handling.

Full Alloy Deck Provides Extra Protection

Our stylish alloy trailer not only protects your hull from road debris but also showcases your craft. Built with the same attention to detail but with an extra dash of zing!
