A multihull series drogue can help prevent capsize or pitchpoling
Catamarans and trimarans have greater windage and generally less body below the surface. This creates an increased risk in storm conditions, when it is critical to control boat speed.
A multihull series drogue can greatly reduce the danger of capsizing and is a prudent addition to safety equipment aboard catamarans and trimarans. The simplicity of the series drogue design and its ease of use, make it the most effective choice for multihull sailors, whilst minimising the risks to crew and boat. By reducing speed to around 2 knots and keeping the boat’s head pointing downwind, the crew can retreat to safety below decks.
In our opinion, a drag device that requires continual adjustment or a helmsman to steer, should be avoided. In these situations, when crew are fatigued or unwell, the chance of a capsize or pitchpole is greatly increased. Despite claims by manufactuers, a parachute anchor is not effective in these conditions. The concept of a parachute anchor is to stop a boat going backwards, whereas a series drogue is to control a boat going forwards. In practice, parachute anchors are either full and exerting dangerous loads on deck fittings, or collapsed and doing nothing ! A series drogue with its multiple cones, directs the boat with constant and manageable forces. The US Coast Guard report concluded “that they could not recommend a sea anchor deployed from the bow of a boat” whereas by contrast they highly recommended the series drogue…
An Oceanbrake multihull series drogue can be custom made specifically for your catamaran or trimaran.
NOTE:- Multihull drogue design differs from mono-hull, resulting in a greater number of cones for equivalent displacement weights.
