Burke Marine


Like all good inventions Seabrake was born out of necessity in a life and death situation in Australia's notorious Bass Strait. Overwhelmed by 80 feet seas and 100mph winds Captain John Abernethy conceived the Seabrake principle when conventional drogues and sea anchors failed.  Seabrake is approved by the Australian Maritime Safety Authority as a sea anchor: Solas certificate #4126 and is compliant with the AYF as an emergency steering device.
