Twin Hull & Multi Docks

Twin Hull & Combo Docks
Tailored Setups for Vessels Up to 5000kgs
 
Our Twin Hull and Combo Drive-On Docks come fitted with advanced 3-Roller Centre Floats, making them a top pick for boats and watercraft weighing up to 5,000 kg. Designed for strength and simplicity, these docks support a heavy payload of 350 kg per square metre and can be customised to suit your exact needs—whether you prefer slide-on or drive-on access for smooth launching and retrieval.
 
Built from heavy-duty HMWHDPE, this dock system is engineered for long-term performance. It stands up to UV rays, temperature extremes, and rough conditions with ease. With operating range from -60°C to 80°C, and an expected service life of 15 years or more, it’s a reliable choice for year-round use. Manufactured using a one-time blow moulding process, it offers exceptional quality, is odour-free, and complies with Australian health and safety standards.
 
These modular docks are easy to handle and quick to install, even in deep water or uneven areas. With non-slip surfaces, no sharp edges, and fully customisable layouts, they’re a smart option for residential waterfronts, private marinas, or even floating walkways.
 
Made from 100% recyclable materials, our HDPE docks provide high load capacity and long-term durability. Available in a range of colours, these docks are designed to be safe, practical, and built to last—with certified tensile strength of over 1950 kg, giving you peace of mind for every launch.

Dock Configurations
Modular Floating Docks can be configured to any Shape & Size (LxW in multiples 0.5m).

For vessels under 5 metres long, we suggest allowing an extra metre in dock length to make sure there's enough room to safely park and secure your vessel. For boats over 5 metres, it’s best to add 1.5 - 2.0 metres to the overall length for safe docking.
 
It's also important to factor in the width of your dock. Be sure to let us know how much side space you need for moving around comfortably and handling your vessel with ease. This ensures your setup is practical, safe, and tailored to how you’ll be using it.
