Seabrake
Seabrake GP30 Storm Drogue for Boats up to 16.8m
The Seabrake GP30 Storm Drogue is a premium heavy-weather safety device engineered for boats from 10.9 to 16.8 metres (36–55ft). Designed and manufactured in Australia, the GP30 helps improve vessel control in rough seas by reducing speed, minimising broaching, stabilising the boat, and enhancing steering performance in following seas. It has become trusted equipment for offshore cruisers, commercial operators, rescue organisations, and naval vessels worldwide.
Unlike conventional sea anchors, the Seabrake uses a unique variable-drag design that automatically increases drag as boat speed increases. Water is dispersed evenly through four exhaust ports, preventing rotation and tangling while providing significantly greater drag than traditional cone-style drogues. This innovative design makes deployment, retrieval, and handling considerably easier while improving vessel stability in severe weather.
The GP30 is suitable for both sailing yachts and powerboats and is an invaluable addition to any offshore safety equipment inventory.
