There are basically three different types of anchors:
* Stockless bower anchor
* Stocked bower anchor
* H.H.R (High Holding Power) anchor

For anchor approved as H.H.P anchor the weight stated in the equipment tables may be reduced by 25%.
Stocked bower anchors are frequently used for mooring of semi-submersible drilling rigs.
We market and stocks huge varieties of anchors.
