The invented sea anchor is made from two sheets of flexible material sewn together to create a generally frustum-shaped body. The body is collapsible and has a first end defining a first opening of a predetermined dimension and a second end defining a second opening of a predetermined dimension smaller than the predetermined dimension of the first opening. The anchor includes at least one fin mounted on, projecting outward from, and extending in an axial direction along the frustum-shaped body. The anchor also includes a flexible stiffener encircling a portion of the first opening. The anchor may also include strapping joined to and extending transversely and axially across the frustum-shaped body. The transversely extending strapping may interconnect a plurality of fins.
A collapsible sea anchor or drogue (50) having first and second hollow frusto-conical body parts (74, 80) which are made from strong flexible material, such as canvas. Four flexible lines (60, 62, 64, 66) connect the two body parts (74, 80) together and to a nose portion (52) to which a towing line can be connected. The sea anchor or drogue (50) is very effective in that the drag is large having regard to the diameter of the body parts (74, 80) and, moreover, it can be compactly stored when in a collapsed condition.
The present invention is a stabilizer ring for a sea anchor, in particular a parachute sea anchor. The preferred embodiment of the stabilizer ring comprises a ring supporting a domed arch. The domed arch has two arch supports that divide the ring into a plurality of sections. Each arch support has a vertex and the two arch supports are connected at their vertices. The domed arch is pivotally connected to a swivel. The swivel has two loops pivotally connected by a bolt.
A drift bag that includes one or more narrowing members to reshape a mouth of the drift bag in the vertical direction to reduce a draft of the drift bag.
