Click to view Yacht Chandlers large selection of Anchors
When it comes to safety quality is everything when buying an anchor.They need to have heavy duty components and consist of strong materials.
On board with you should always be a heavy duty Anchors
for all seabed types you can expect to encounter. In tight anchorages you will need both a bow and stern anchor.
There are three type of anchors: Deep penetrating Anchor:
These anchors have lightweight, pivoting flukes and Danfoth and Fortress anchors. These anchors apparently have the greatest holding power.Plow-Style Anchor
: These anchors do not penetrate as deeply as the previous type but have excellent structural strength and include Bruce, Delta, CQC, Spade and Max anchors.Speciality Anchor
: These anchors are specific to particular seabed types.
Studies have shown that when it comes to selecting an anchor it is more important to consider the conditions of the seabed over the design of the anchor.Anchoring to the SeabedAnchoring in Sand:
This surface is relatively easy for anchors to penetrate and most anchors hold very well in hard sand.Anchoring in Mud:
Mud has a low sheer strength on the surface so the anchor needs to be able to penetrate down to an area of greater sheer strength. This requires an anchor with A greaer fluke are and a wider fluke angle. An example of an anchor that works well in these conditions is a Fortress anchor.Anchoring in Rock and Coral -
Plow and grapnel anchors generally work better on this type of seabed. Examples include Bruce, CQR, Delta and Yachtsman anchors.Anchoring Shale, Clay or Grassy Conditions
: All anchors can struggle with this type of seabed; in this situation weight is more important than design. CQR, Delta and Yachtsman anchors have the ability to penetrate grassy bottoms however the roots may cause a "false set" as they can often masquerade as something more solid. What size anchor do I need?
It is important that every vessel has at least one adequately sized anchor on-board. As a general rule of thumb the anchor should weight the same as the vessels length in ft. For example a 32ft vessel should have a 32lb anchor. However the manufacturerÆs instructions and builders recommendations should be adhered to at all times. If in doubt it is always better to carry an oversized anchor than an undersized one.
