Navigation Buoys

For demarcation and navigation purposes in marine, coastal and offshore areas.

Ecocoast offers one of the most comprehensive lines of marine Aids to Navigation (AtoN) solutions to aid safe navigation worldwide. A full range of navigation buoys, lanterns and mooring systems is available. More here about Hyperion, solar LED marine lanterns for demarcation purposes, and Ecomoor, the next-generation of mooring systems.

We provide GISMAN Polyethylene Buoys and an in-house designed and manufactured range of buoys under the brand Ecobarrier®. All navigation buoys are successfully being used to demarcate a variety of marine and coastal areas, such as waterways, marinas, rivers, port entrances, ocean and offshore locations. We call our full offering ‘Navigating Smart’ to help you navigate smarter.

All buoys can be customized with mould-in graphics, solar lanterns/panels, signage, radar reflectors or monitoring systems. They are highly visible, conform to IALA guidelines (International Association of Marine Aids to Navigation and Lighthouse Authorities). They are designed for harsh UV environments, using the highest quality UV-stabilized virgin polyethylene. In addition, they seamlessly connect with other marine demarcation barriers.

Get in touch to find out how to navigate safer & smarter. Our team is highly trained in identifying the right specifications & designing navigation requirements, as per IALA norms.

GISMAN Navigation Buoys

Ecocoast - Aids to Navigation

Ecocoast boasts a comprehensive range of high quality, performing Aids to Navigation solutions suiting all marine environments.

Eight more navigation buoys were added to the existing Ecobarrier® range a couple of years ago, suitable for proximity beaconing, shallow waters, fast current zones, port beaconing, semi-exposed or sheltered sites, coastal and offshore applications.

All buoys are manufactured from strong, durable UV-stabilized virgin polyethylene, pre-compounded to reduce colour ageing and with expanded polystyrene (EPS) foaming. EPS foaming offers many advantages, such as higher buoyancy, higher impact resistance, 95% water tightness and no impact on the environment. EPS is used for all GISMAN buoys, offering a clear advantage over other buoy manufacturers.
