Concrete Pontoons


SF Marina offers a wide and versatile range of concrete pontoons. Pontoon widths range between 2.4 and 10 meters. Freeboards range from 50 cm to 100 cm. Almost without exception any length can be custom made, any angle can be manufactured and any configuration can be built. Utility ducts can be customized to any need, large or small. The SF Marina concrete pontoons are all wave attenuating, due to a low center of gravity, which allows for installations where swells and waves are predicted to be somewhat more severe.

Thick cover layers of strong, high-quality concrete protect the reinforcement, delivering the longest lifetime of any concrete pontoons on the market today. Concrete pontoons will deliver an esthetic, clean, uncluttered, and safe mooring for all marina guests, in all weathers.

All concrete marina pontoons are fitted with a pressure treated wood fenders, bolted to the concrete body using marine grade stainless steel bolts in stainless sockets, adding 250 mm to the concrete width of the pontoons.

Anchoring points for any concrete pontoon can be either eyes or anchoring wells when chain/rope and anchor is to be used for anchoring. If pile anchoring is to be used, cast in tracks for attachment of pile guides alternatively internal pile guide recesses are cast in.

Stainless steel sockets can easily be cast in for any auxiliary equipment such as flag posts, safety equipment or bollards.

In many cases, the concrete pontoons are decked with various materials ranging from exotic wood to plastic composites.

Choosing a concrete pontoon

A Pontoon’s wave dampening properties are determined by its width, weight, depth and presence. All concrete pontoons are wave dampening and can be simplistic to say that a pontoon moderate waves with a wavelength corresponding to the pontoon width. Our terminology is based on the first two digits of the type name specifies concrete height in dm and the last two digits indicate the breadth of dm.

For large wavelengths, or deep-improved path loss on the pontoon equipped with turbulence chamber (wings). Our pontoons are equipped with “wings” out in the type name of the concrete width in cm, ie a SF400 has a concrete width of 4 meters.

The freeboard is determined by the pontoon’s own weight versus the volume of water which it replaces to float. Heavy pontoons flows for a given geometry with a lower freeboard.
