The present invention of MagDrag relates to methods and apparatus of a magnetic hull attaching sea anchors to slow down and impair the forward motion of sea vessels. The basic MagDrag device includes four major components, a large magnet, a pump, a sea anchor bag and a buoy.
Claims15
Apparatus for attaching a sea anchor to a ship, the apparatus comprising:
- a buoyancy device for supporting a magnetic plate and an inflatable sea anchor while placed in water;
- a magnetic plate attached to the buoyancy device and supported by the buoyancy device while the magnetic plate and the inflatable sea anchor are in water;
- and
- a pump for pumping sea water into the inflatable sea anchor and thereby inflate the inflatable sea anchor with sea water such that when a vessel comprising a steel hull impacts the buoy, the magnetic plate becomes fixedly attached to the steel hull and the inflatable sea anchor provides drag on the steel hull.
