Frequently Asked Questions (FAQ)

Expert answers regarding installation, durability, and global shipping for modular pontoons.

How does the Floating Dock system hold up to typhoons?

Floating Dock's modular design and superior quality hold up quite well in a typhoon depending on the installation. Our customers are reporting excellent results for the docks that were hit head-on in all typhoons. Proper anchoring and flexible connecting pins absorb extreme wave energy effectively.

Can I get a Floating Dock system if there is no dealer in my area?

Yes. In areas where there is no local dealer presence, we can ship your Floating Dock system directly to your local freight terminal for convenient pickup, complete with comprehensive assembly guides.

Can I leave my dock in during the winter season?

Absolutely. The dock can be left in all year even in salt water. The Floating Dock system is designed to be left in the ice for the winter. The special design of the cube allows the dock to pop up safely on top of the ice.

How does ice affect the system?

The main issue with ice is water flow. If there is a heavy current or moving ice blocks that could smash stationary structures, caution is required. If the ice simply thaws and dissipates in place, our dock can safely remain in the water all year round.

How many cubes wide for a stable walking platform?

The available walking platform must be at least three cubes wide for optimal stability. The dock is extremely stable to walk on and comfortably supports body weights due to the balanced buoyancy of each cube (approx. 200 lbs buoyancy).

Will the system work in shallow water?

Yes, you can use the dock anywhere you can drive your watercraft. The cubes only draw about 2 to 4 inches of water. The system is completely fine resting on the bottom during low tides as long as there is sufficient depth at the stem for craft maneuvering.

How long have you been in the floating dock business?

Our factory started our floating dock business in 2019, emerging as one of the earliest specialized floating dock manufacturers in China, delivering super quality products to worldwide clients.
