Benefits of technology

This patent describes a sea anchor device that can be used to control the speed and position of watercraft with respect to the wind. The device includes a link for securing the anchor to watercraft and a cable or rode that is attached to the link and a connector. The connector is also affixed to a durable rigid funnel which is attached to a sea anchor. The sea anchor is affixed to the boat using a link and a removable clip or other suitable means. The funnel is made of a rigid and durable material to prevent entanglement with the cords and is easier to open and close than a fabric canopy sea anchor. The stem of the funnel may have holes to attach additional sea anchor devices for increased resistance or to connect with another sea anchor device in series. The technical effects of this invention include improved control and stability for watercraft, as well as increased safety and durability of the sea anchor device.

Problems solved by technology

However, these canopy style anchors suffer from several disadvantages.
The canopy style anchors are not easy to deploy, store, pick up, or retrieve.
The canopy style anchors are prone to tangling cords, wear and tear, and do not allow for connection of additional canopies.

Embodiment Construction

[0018]The present invention is a sea anchor 10 that is durable, easy to retrieve, pick up, and store, deploys quickly, is always open, and reduces the chances of the cords fouling. The sea anchor 10 is useful in controlling the speed and position of watercraft such as a small boat, kayak, or paddle board. In one embodiment shown in FIG. 1, the sea anchor 10 includes a rode 14 affixed to stern of a boat 40 by a link 12. The link 12 may be a removable clip, carabineer, knot, or any other suitable means for affixing the rode 14 to a boat 40. The rode 14, which may be a cable, rope, or chain, may be affixed to the link 12 at one terminal end and to a connector 16 at the opposite terminal end, thereby joining the sea anchor 10 to the boat 40. A rode 14 may be made of strong materials in order to resist the tensile forces created by the interaction of the boat 40, wind, and water. Additionally, a rode 14 may be elastic to absorb some of the shock load and tensional forces created by the i...

Abstract

A sea anchor that is durable, easy to retrieve, pick up, and store, deploys quickly, is always open, and reduces the chances of the cords fouling is disclosed. The sea anchor is useful in controlling the speed and position of watercraft. In one embodiment, the sea anchor includes a link for securing the anchor to watercraft and a rode attached at one end to the link and at the other end to a connector. The connector is also attached to a multitude of funnel cords which are affixed to a durable rigid funnel. In one embodiment the connector is a hollow conical shape with holes for attachment of the rode and funnel cords. The funnel can have tabs adjacent the mouth of the funnel for the connection of the funnel cords and fins around the stem for orientation of the funnel when in use.

Description

CROSS-REFERENCE TO RELATED APPLICATION[0001]This application claims the benefit of U.S. Provisional Application No. 61 / 953,406, filed Mar. 14, 2014.BACKGROUND OF THE INVENTION[0002]Sea anchors have been used to control boat position and speed of drift in heavy seas for hundreds of years. A variety of modern commercial sea anchors exist including a parachute style canopy made of fabric which is connected by many cords to a single line that is then attached to the bow of a boat. To slow or stop a boat from drifting downwind, the sea anchor is tossed into the water. Once the anchor is in the water, the canopy opens and catches the water and creates resistance, which slows the drift of the boat and positions the bow so that it faces into the wind and waves. This anchoring device has saved many ships and smaller craft from rolling sideways and capsizing in heavy winds and seas.[0003]However, these canopy style anchors suffer from several disadvantages. The canopy style anchors are not ea...
