CATAMARAN BUOY FOR RIVERS & ESTUARIES IDEAL FOR FAST CURRENTS

By adapting the well known twin hull catamaran design to carry lighting equipment for night navigation and large daymark for day navigation, a new type of floating navigational marker is now available for use in rivers, partially sheltered estuaries and bays with fast flowing tides. The small draft is ideal for shallow water or where sites dry out and the twin-hull design is exceptionally resistant to rolling. The catamaran buoy weighing very light is easy to handle, and its good towing characteristics and light weight moorings, enables it to be towed to and from site, laid and recovered by a small Service Launch.

The hulls are made from strong Glass Re-inforced plastic (GRP) and filled with polyurethane foam to render them virtually unsinkable. No painting is required and maintenance is minimal.

The catamaran buoy is offered with our self contained LED beacon type MLB-200-6 The solar panel and the battery is assembled on the GRP beacon body. The beacon is designed to give in excess of  6 n. mile range with 21 days of autonomy period.

·         A radar reflector is fitted inside the daymark.
