The Original Rocna Anchor

The Original Rocna Anchor

Introduction:

The original Rocna anchor was designed by New Zealand sailor Peter Smith. Among all the anchor types, the concave anchor claw has greater resistance. The sharp anchor claw of the Rocna anchor can penetrate even on the harder seabed. For Rocna anchors, all sizes that we can provide can be made of stainless steel or hot-dip galvanized.
