The Marinova heavy concrete pontoon is a high-stability floating structure designed for use as a main marina walkway and berthing platform in semi-sheltered to open water environments. Its substantial mass, low centre of gravity, and reinforced concrete construction provide exceptional stability, comfort, and durability under operational and environmental loads. The pontoon system is engineered for long-term deployment in marine conditions, with a design focus on structural robustness, minimal movement, and low maintenance. The modular configuration allows flexible marina layouts with straight or angled connections, without the need for intermediate gangways.
