Flexibility, modularity and exceptional floatation

Nos cubes flottants modulaires peuvent s'adapter à tous les plans d'eau et à tous les projets

The assembly by connecting pins every 50cm gives a pontoon made of cubes ​​incredible flexibility, reducing its resistance to waves and allowing it to withstand exceptional tidal conditions and weather.

This foolproof flexibility is undeniably the great strength of these pontoons that can be installed in the open sea or any other body of water exposed to difficult conditions.

With a load capacity of 87,5kg per cube (model A), this solution also offers exceptional buoyancy of 350kg/ m², which value may be multiplied by 2 or 3 by stacking layers of cubes.

In addition, total modularity allows it to adapt to all sites for all projects, but also to all budgets. If this criterion is essential in the development of your project, our double cubes and double cubes with low freeboard will grab your attention.


The assembly of modular floating cubes is extremely simple. Each SunnyDock cube has 4 ears on each angle which enable assembly by the connecting pins tightened by means of a locking key. The cubes are also connected on the periphery using a coupler comprising of a screw, a nut and washers to compensate height differences between the ears.
