Our drive-on/off modular floating docks are built to handle a 350 kg/m² payload, designed for both mono and twin hull vessels up to 5,000 kg.
Universal Centre float for U-Shape Hulls and suitable for V-Shape Hulls.
 
Made from heavy-duty HDPE (HMWHDPE), these docks deliver outstanding durability, UV resistance, and impact strength. Operating between -60°C and +80°C, they are suitable for Australia’s toughest conditions and provide a service life of 10–15 years.

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.
