A sea anchor comprising a body of flexible material, a plurality of connectors linking the periphery of the flexible material to a centrally positioned rigid stem, a piston member slidably mounted within said stem and adapted to project from said stem when the sea anchor is in use, the outer extremity of said piston member being secured to the flexible material, a first tow line being secured to the closed end of the central stem and a second line passing through the central stem and being connected to the internally mounted piston member, withdrawal of said second line resulting in the retraction of the piston member and the collapsing of the sea anchor. |
