Mobilis Trackless buoy

The Mobilis Trackless unit is a cost-effective, streamlined platform designed to minimise the heeling problems associated with buoys in strong tidal flow conditions. The carefully designed combination of hull and rudder plate attains superior stability and six times less drag than a conventional buoy of similar size. Manufactured using rotationally moulded medium density polyethylene (MDPE), the buoy’s simple construction is low maintenance, low cost and extremely lightweight. The 0.9m wide and 2.0m long hull will accept the same daymark and topmark sections as the M 1200 buoy and can easily be fitted with a small self contained light..

DataFish marker buoy

For extreme wave and tidal conditions the Mobilis Trackless buoy would be too small a platform.  The DataFish platform is suitable for up to 5m/s tidal flows and wave heights of up to 9m.  It is manufactured using infused GRP with marine grade aluminium parts. Two sealed compartments provide accommodation for battery packs and instrumentation. For more information on the DataFish buoy see the datasheet above or visit: http://northseasystems.com/
