Challenge, Adventure and Fun on Land and Sea

ANCHORS Everyone knows about anchors; they are used to fasten things to something else. Anchors are particularly important on boats to attach the boat to the bottom of the sea, lake or river. To stop for lunch, overnight or to moor your boat you need an anchor. You also need an anchor in emergency situations like the time I and a friend were caught in a tropical storm on the Little Bahama Bank. The wind was so strong that the dinghy that we were pulling was lifted out of the water and was twirling like a propellor. Fortunately we had a storm (large) anchor on board and after untangling the line, being careful not to be caught up in it, safely anchored. There are a number of types of anchors useful in different situations. Desirable features include good holding power in all bottom conditions and not breaking out in shifting winds and tides. Fluke style anchors are good in sand and mud, but not good in weeds, rocks or hard sand or clay. They are light in weight and very popular, but tend to break out in shifting winds and tides. The aluminum Fortress anchor (www.mountains-and-seas.com) with its excellent holding power, life-time warranty and adjustable fluke angle is the best performing example of its kind. Plow style anchors are heavier than fluke style anchors and are shaped as the name implies and hold well on most bottoms except deep mud and tend not to break out with changes in wind and tides. Grapnel anchors are good for such small boats as canoes, dinghies, etc. The folding type is very compact and easy to store. In choosing an anchor consider the size of your boat and the bottom conditions where you will be boating. Also it is wise to carry an extra anchor or two on board. Anchors are attached first to a chain which because of its weight tends to pull horizontally on the anchor helping to set it and then to a line, called a rode. A ratio of 7 to 1 between length of rode and water depth is usually sufficient; however, in extreme conditions the ratio should be increased. In the situation mentioned above we let out all the available line. In anchoring many boaters throw their anchor; however, the recommended procedure is to drop it vertically and then to back down on it with the motor, wind or tide to set it. Be careful not to get your feet entangled in the rode as it plays out.
