ABSTRACT:
A sea anchor having a leading edge that is outfitted with a flexible, resilient hoop member that biases the leading edge to self-expand. The hoop member is constructed from a material having no shape retaining memory and in a presently preferred form comprises a looped length of a coated spiral spring. A relatively substantial float extends along a substantial portion of the leading edge circumference and is mounted between a pair of short tether lines. Weights are mounted to the leading edge diametrically opposite the float and between a pair of longer tether lines. Vents mounted between the float and trailing edge release trapped air as the anchor inflates with collected water. A retrieval line is secured to guides along the length of the anchor and a storage strap is secured to the anchor.
