    Basically, each bottom that you fish requires a different type anchor. Mud requires a fluke style anchor, or a mushroom that will dig into the muck and hold your boat. here is more of the anchor data.



    Anchors and Ground Tackle

    If you go boating long enough, sooner or later you're going to need to anchor. Knowledge of your anchoring equipment (called ground tackle) and the ability to use it is an absolute necessity. Many of today's power boaters just go from marina to marina and, as a result, are unfamiliar with their ground tackle and how to deploy it. Worse yet, some boaters don't even have an anchor aboard!

    Think about it. You and your family are out for a fine day of boating, when your engine breaks down and cannot be restarted. The wind is blowing you towards a rocky shore and the waves are getting larger. At this point, you need an anchor and the knowledge of how to use it. Otherwise, you risk losing your boat or, possibly, worse things!

    Let's take a look at the 3 basic types of anchors available:

    Patent Anchor: The Danforth© anchor is the best known of this type. Its advantages are that it is lightweight with good holding power and stows flat. However because of its light weight, it has difficulty penetrating thick weeds or hard bottoms.

    Plow Anchor: The plow anchor is so named because it looks and performs like a plow. It holds well on almost any type of bottom conditions. The plow anchor, however, is heavy and very difficult to stow unless you have a bow pulpit and roller.

    Mushroom: The mushroom will sink down into the mud or sand. If left long enough, it will have tremendous holding power. Most permanent moorings use a large mushroom anchor.

    Since storage space is always at a premium on boats, the number of anchors you carry and the type you decide to have must be compromises between safety and convenience. Anchors are rated by their horizontal load capabilities.

    Here are some approximate horizontal load requirements for various boat lengths:


    Boat Length (feet) Protected Waters (lbs) Unprotected Waters (lbs)

    20 360 720
    30 700 1,400
    40 1,200 2,400
    50 1,600 3,200


    When looking for an anchor, check the manufacturer's stated horizontal holding power. If you have any doubt, remember that an anchor that's a little too big is much better than an anchor that's a little too small!

    Your anchor line is called a rode. Nylon line is the best choice here because of its strength and ability to stretch. It's also a good idea to have a 6-foot to 12-foot piece of chain between the anchor and the nylon line. The chain really helps to keep the anchor (stock) parallel with the bottom and also acts as a shock absorber.

    Your anchor rode must be long enough to create a horizontal, rather than vertical, pull on your anchor. Anchors are designed to dig in deeper when they are pulled horizontally. They are also designed to come free when pulled vertically.

    There is a simple formula which helps calculate the proper scope (length) of rode you need. Take the height of the boat's bow from the water line and add it to the depth of the water. In this example, we'll say the height of the bow from the water line is 3 feet, and the depth of the water is 12 feet.

    Example: 3 feet + 12 feet = 15 feet

    If you are in a well-protected area (no waves or wind), multiply the total by a factor of 5.

    Example: 15 feet x 5 = 75 feet of rode needed

    If you are in normal conditions (some wind and some waves), multiply the total by a factor of 7.

    Example: 15 feet x 7 = 105 feet of rode needed

    Finally, if you are in rough conditions, multiply the total by a factor of 10.

    Example: 15 feet x 10 = 150 feet of rode needed

    REELFUN,we call those wreck anchors down here.There are two theories;1 get the kind with the soft aluminium tines that you can straighten out easily.;2 get the kind,usually locally manufactured that have a ring on the bottom that you tie the anchor line to.Then you fasten the line to the top of the shaft with plastic ties so when it gets stuck,(Notice I said when not if) you pull hard ,the tie breaks and you can pull it out backwards.These work great and generally 98% can be retrieved with a little work.:tounge_out:
