What is the Pontoon 330 kit?
The Pontoon 330 is a DIY floating dock kit measuring 3.7 metres x 2.46 metres. It is designed for residential waterfront applications and can be supplied as a complete kit or as individual components.

Can I build my own pontoon?
Yes. Marine Dock Systems supplies pontoon kits with detailed drawings and assembly information, making them suitable for DIY construction by homeowners, boat owners and waterfront property owners.

What comes with the Pontoon 330 kit?
The kit includes polyethylene flotation modules, aluminium brackets, stainless steel fasteners, cast aluminium mooring cleats and PVC buffer systems. Timber is supplied separately unless otherwise specified.

What size is the Pontoon 330?
The Pontoon 330 measures approximately 3.7 metres long by 2.46 metres wide, making it ideal for residential waterfront properties, rivers, canals, lakes and marina berths.

What flotation system is used?
The Pontoon 330 uses four UV-stabilised polyethylene flotation modules with a capacity of 650 litres each, providing excellent buoyancy and long service life in marine environments.

What decking options are available?
Two decking layouts are available. Option 1 features decking installed crossways, while Option 2 features decking installed lengthways. Both designs use the same flotation and bracket system.

What timber is recommended?
Marine Dock Systems recommends quality marine-grade hardwood timber such as Queensland Blackbutt F27 hardwood for durability, strength and long-term performance in waterfront environments.

Are the floats made in Australia?
Yes. The polyethylene flotation modules are Australian made and manufactured using high-quality UV-stabilised materials designed for harsh marine conditions.

What materials are used in the pontoon kit?
The kit uses polyethylene flotation modules, marine-grade aluminium brackets, cast aluminium cleats and 304 stainless steel fasteners to maximise corrosion resistance and durability.

Can the Pontoon 330 be supplied fully assembled?
Yes. The Pontoon 330 can be supplied as a DIY kit or delivered fully assembled and ready for installation, depending on customer requirements.

What applications is the Pontoon 330 suitable for?
The Pontoon 330 is suitable for private jetties, residential docks, waterfront homes, boat mooring platforms, fishing pontoons, swimming platforms and recreational marine access structures.

Does the kit include mooring cleats?
Yes. The standard Pontoon 330 kit includes four cast aluminium mooring cleats designed for securing boats and watercraft safely alongside the pontoon.

Does the pontoon include protective buffers?
Yes. The standard package includes large PVC buffer sections fitted to three sides of the pontoon to help protect boats and the pontoon structure from impact damage.

What tools are required to assemble the pontoon?
Basic construction and hand tools are generally required. Detailed assembly drawings are supplied and Marine Dock Systems can provide technical assistance if needed.

Why choose a Marine Dock Systems pontoon kit?
