The holding power of any anchor is directly related to how deeply it sets and holds the sea bed. Most anchors on the market today are restricted by design to ploughing along near the surface of the sea bed and rarely, if ever disappear completely below the sea bed. Cooper Anchors very simple design with its weighted tip and straight streamline shank are designed to completely disappear below the sea bed and stay there even through wind and tide changes. The small area between the shank and the tip, (see diagram below) allow Cooper Anchors to change direction with less effort, especially during anchor retrieval. As the boat is pulled forward, over and above the anchor, the anchor rotates with the vertical pull and is easily retrieved.

The small blade on the shank of the Cooper Anchor completely eliminates the possibility of the anchor staying on it’s back. By creating a new balance point that rolls the anchor onto its tip and sets immediately. The small blade also increases holding power and stabilizes the angle of attack as the anchor buries because the small blade and the main blade are at the same angle and support each other. All of these features ensure the anchor sets deeply and provides the maximum holding power for your safety and pleasure.

When anchoring in sand, mud or through a change of tide or sleeping over night, shackle or tie your rope/chain through the main hole.

Protecting Our Reefs

Shackle or tie your rope or chain through hole B and use a cable tie through the main hole A. If the anchor becomes stuck, as you pull up, the cable tie will break and the anchor will release backwards without damaging the reef or the anchor.
This method should only be used in reef.
*Hint; When using a cable tie, put it through the anchor twice before going around the rope or chain so you don’t leave it behind when it breaks.

Cooper Anchors are sold as a bare unit without rope/chain for purposes of shipping.  Chain (if required) and rope are available from most hardware stores.

Anchoring/Rope Guide:

Option 1:  (No chain)  7:1 = 7 meters of rope for every 1 meter of water depth (shallow areas)

Option 2:  (With chain)  4:1  = 4 meters of rope, including a small lenth of chain, for every 1 meter of water.

Instructions:  Attach chain on d-shackle through hole closest to the scoop.  Run chain to back and use a small tie down to attach chain to rear hole.  If the anchor ever becomes lodged, the tie down will break and allow the anchor to pull free.
