Ø3000mm Seagull Navigation Buoy


JFC are delighted to introduce our new range of Seagull Navigation Buoys, which aim to set a new standard in floating Aids to Navigation. This modular buoy is designed for use for both inshore and offshore applications.

This buoy has been designed with an emphasis on durability, flexibility, and economy throughout. It features a unique hull, central core and ballast arrangement, with a modular adaptable day mark. It also boasts excellent structural stability characteristics, power versatility and environmental credentials.

Made from rotationally moulded UV stabilised virgin polyethylene designed especially for marine applications (UV15 rating). Extra strength mooring and lifting eyes ensure ease of manoeuvrability and improved mooring flexibility and service life of the buoy.

By addressing key design criteria it can reduce costs and maximise servicing intervals. Safe access for maintenance personnel and ease of operation have been prioritised as have all deployment, mooring and retrieval requirements.

The Seagull buoy range is manufactured in accordance with the IALA (International Association of Marine Aids to Navigation and Lighthouse Authorities) high visibility colours and shapes to suit a arrange of installation requirements. (Guideline No: 1006)
