Larger yachts occasionally have spring-loaded chain stoppers for this purpose. We prefer to tie light-duty three-strand nylon between the bow cleats and the chain. In heavy winds we use a 20-foot (6-meter) long piece, which will stretch 4 or 5 feet (1.3 meters) under load.
The chain is left in a loose loop between the cleat and the end of the nylon, so as the nylon reaches the end of its stretch, the chain again takes the load directly.
This line should be the smallest that will take the load, in order to provide the most elasticity. (The smaller it is, the more elastic.) On Intermezzo, a moderate windage vessel, we used a piece of 5/16-inch (8-millimeter) nylon and never had a problem. Intermezzo II, with perhaps 50-percent more windage, used a 3/ 8-inch (9.6-millimeter) piece of line. On both Sundeer and Beowulfwe use 7/16-inch (11-millimeter) three-strand nylon.
In a really heavy blow, or with a sea running, even if you have unlimited swinging room and lots of chain veered, at some point the chain will snub up tight. If this happens the single-shock line shock absorber should be augmented with a second line.
Another way to reduce loads is to lower the attachment point of the rode on your bow to an eye at the cutwater. The lower pull flattens the angle point of the rode to your bow.
A chain hook (shown above and in the drawing below) is the easiest way to connect a snubber to the anchor rode.
The longer the snubber line, the better the shock absorbing characteristics. The snubber in the photo above is much too short. In the drawing below, note the attachment for the snubber line at the cutwater. This substantially reduces the amount of rode required to achieve a given scope, especially in shallow water where the freeboard forward can increase rode needs by 30 percent or more. Note: In the absence of a chain hook a series of half hitches will work, albeit not as efficiently.

Lets start by identifying what exactly certain boats are. Sometimes the terminology can get lost on beginners, so well look at some of the most common boats and what theyre called. These boats are exactly what the name implies. They are meant to be used for fishing. Most fishing boats are powered by outboard motors, and many also have a trolling motor mounted on the bow. Bass boats can be made of aluminium or fibreglass.
