In our stand there were three anchors:
the 400kg stainless steel HV anchor, the king of welded anchors, suitable for any type of seabed.
A galvanized HVFB 410 Kg anchor with stainless steel bottom, FB stands for Fully Balanced: anchors that remain with the flukes raised instead of lowered; when the bottom is present they are always balanced.
Both the HV anchor and the HVFB allow a weight reduction of up to 25% compared to a normal anchor.
The smallest was “only” 97 kg, a galvanized PTW+ anchor with stainless steel plate. Super High Holding Power anchors allow a weight reduction of 50% compared to a normal anchor.
The plate can be made of a different material than the anchor. In these last two models the anchors were hot-dip galvanized with a mirror polished stainless steel plate. Both HVFB and PTW+ can have the shank shortened by 10%.
