Cooper Anchors - How to

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.

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.

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.

All size and scope recommendations are as a guide only for relatively calm water in good anchoring conditions. Where conditions are not favourable, rough seas, fast currents or strong winds, more scope or a larger size anchor should be considered.

Frequently Asked Questions

Question 1.    Do I need chain and if so how much?
ANSWER   (See Anchor Guide above)
Question 2.    Will they work on reef?
ANSWER     (see Protecting our Reefs)
Question 3.    How well do they work in mud or shaly bottoms
ANSWER    Because our anchors dig deeper than most, if not all other anchors, they perform well in a variety of sea beds. There are however some areas where no small anchor will work well.
Question 4.    Will the plastic anchor sink?
ANSWER   Yes, there is a heavy weight in the tip of our nylon anchor.
