FOR SALE – 16 x 1200L Polyethylene Floats (Marine Dock Systems)
We’ve got 16 x 1200L floats up for sale – only used once on a movie set and still in perfect usable condition.
Each float is:
• 2.0m long
• 1.2m wide
• 540mm deep
When assembled tight, they make a platform approx:
9m x 5.2m (see frame drawing included)
✔ Made from tough polyethylene
✔ Built by Marine Dock Systems
✔ Each float rated to 600kg load capacity
✔ Total combined capacity: 9,600kg
💡 Flexible setup:
The overall platform size can be made larger by spacing the floats further apart. Just ensure your frame is designed correctly and you keep the total weight of your structure within the load limits.
They’ve got a few scratches and are a bit dirty from use, but nothing that affects performance – solid, reliable gear ready to go.
Perfect for:
• Floating house / houseboat base
• Pontoon dock (large setup)
• Marina use
• Floating walkway
• Work platforms
📍 Located in Coolum Beach, Sunshine Coast
Total price for all 16 floats $8,000
or $500 EACH
