Having the right anchor and cable for your boat is important. If you don’t, rough winds and water can cause it to drag, leaving your boat to drift. This is especially dangerous if you are asleep or swimming nearby. Make sure that your boat is well anchored and that the swivel is properly locked, and keep watch to detect signs of dragging.
When selecting an anchor, its holding power and the type of seabed in which it will be used must be considered. As well, the anchor must be of proper size depending on the pleasure craft. It is best to have a heavier anchor than needed, because a lighter anchor will not keep the pleasure craft in place during bad weather conditions.
Regardless of the type of anchor, it must fitted with not less than 15 m of cable, rope or chain or any combination of them, carefully secured to the bow of the boat. Transport Canada require a minimum length 5 to 10 times the depth of the water when dropping anchor line on a pleasure craft. Neither rope nor chain is fundamentally superior. They each have their advantages and disadvantages. However, for small boats, it is recommended to attach an elastic element such as a bending or a shock absorber to the anchor line, in order to absorb sudden shocks that can occur.
