Sea anchors stabilize boats by catching water and slowing them down, using drag to keep them on course. They are made from parachute material and can be easily assembled in an emergency. They are vital in high seas and storms, and can also be used to prevent drift and conserve fuel.
A sea anchor is a useful and sometimes vital piece of ship’s equipment. Unlike normal anchors, sea anchors do not sink to the bottom to hold a boat in place, but use the power of the water to provide resistance and stabilize the boat. Sea anchors are widely used by sailors on many different types of vessels; Anglers, pleasure cruisers, and even kayakers can benefit from an anchor of some sort.
Sea anchors work by allowing a cloth-based platform to catch water as the ship travels, which actually slows the ship down. By setting the anchor at specific angles to the boat, sailors can take advantage of drag to keep the boat on the proper course, even if the steering systems or engines fail. The anchor is attached to a flexible line or rope, which is attached to the boat. Some models may also feature a secondary line that allows the anchor to be towed easily, which is particularly important on larger anchors that can be easily weighed down by water.
One excellent advantage of a sea anchor is its flexible design. Commercially available sea anchors are often made from parachute material, which gained popularity during World War II as an upper fabric for the purpose of creating strength. Although sea anchors can be purchased, they are also easy to assemble with available materials in an emergency. Sailcloth attached to a wooden frame can easily function as a sea anchor if a commercial version is not available.
The most vital use of sea anchors occurs when seas are high and storms or winds cause emergency conditions. Although a skilled sailor can handle the boat properly in these conditions, a sea anchor can stabilize the boat against strong seas and winds, allowing sailors to focus on repairs and safety precautions. Trying to steer a ship through a storm can be backbreaking work; By using sea anchors correctly, the helmsman can conserve energy.
Sea anchors are also used to prevent or retard drift. Anglers often use the device for this purpose, in order to take better advantage of large schools of fish in one location. By slowing the boat’s drift with an anchor, fishermen can save fuel and keep engines off while they work. For voyages that require overnight breaks at sea, a sea anchor can also reduce drift to keep the ship in a relatively stable position. In the event of engine or instrument failure, drift reduction can also help rescuers easily locate the vessel based on last known coordinates.
