Pontoons 3300, 3800

The Breakwater Pontoons 3300 and 3800 are popular and widely used floating solutions to protect marinas. The pontoons are extremely strong and designed to endure all sea conditions. Due to their massive and stable construction these pontoons are also used as landing stages and overpass bridges. The Marinetek Breakwaters without keels work best when the sea wave length is less than 18 m. The Marinetek Mooring System and Seaflex mooring arrangement is a standard for easy and safe mooring. Chain mooring can also be used.
