Our Research and Development started over 8 years ago. Our aim was to produce smaller more effective anchors that would bury deeper, in fact, completely out of site. With each design improvement we were able to reduce the anchor's size and weight. This process was repeated hundreds of times. We now have a small aluminum anchor range. Our smallest weigh less than 1.5Kg and easily hold Jet Ski's or small boats to 3.7m in length.
How and Why They Work (or Click On Video)
Most one piece anchors use either a long curved shank or a roll bar to assist in rolling the anchor off its back. We tested these options with our own prototypes early in our R&D program. We found they added extra weight and resistance to its movement down into the sea bed. Prototypes with role bars had areas that became blocked with rocks, coral or mud that stopped the anchor from working and had to be cleared by hand. Cooper Anchors have now overcome these imperfections with the addition of a small blade.
The Small Blade completely eliminates the possibility of the anchor staying on its back by creating a new balance point. This new balance point enables a greater percentage of the anchors total weight to be exerted by the tip, onto the sea bed, causing the anchor to set 
quickly and more reliably. The small blade also provides additional surface area, and 15% more holding power. In addition the small blade assists in maintaining a perfect angle of attack as the anchor buries into the sea bed.
The Shank can now be made straight, shorter, lighter and thinner as a result of the new small blade. All of these improvements mean less resistance to the anchor moving down deeper into the sea bed. The shank is also mounted further forward on the main blade. The new forward position of the shank makes it easer to retrieve, and minimizes the chances of becoming permanently hooked on reefs. This new position eliminates the need for slotted attachment points that can cause the anchors to come out at times that are undesirable, for instance during changes of tide or wind direction, especially when boats are left anchored and unattended.
Protecting Our Environment - An Old, But Very Good IdeaSimply move the D shackle to the hole at the
base of the shank. Then cable tie the chain to the
top hole. |

If the anchor becomes stuck, the cable
tie brakes and the anchor is removed backward.
You get your anchor back without damaging the reef
or the need to carry an additional reef anchor. When
anchoring in anything other than reef the main hole
should be used.
Field tests have been carried out over a number of years in a variety of sea beds and as many of our customers have testified, they set fast and hold very well in most sea beds. Because Cooper Anchors are smaller than most anchors, there maximum holding power can take a few seconds longer to be achieved. It is as the Cooper Anchor moves deeper into the sea bed, that their outstanding holding power becomes very evident.
