For excellent holding power, cast iron or steel mooring
anchors such as these pyramids are far superior to granite or
concrete blocks.
Pyramid shaped one-piece cast iron permanent mooring/anchor for
fresh and salt water use
Mooring will rapidly set itself by presenting a digging edge to
penetrate the bottom
Short shank allows mooring in more shallow water with less
chain wrap-up and potential hull damage
For excellent holding power, cast iron or steel mooring
anchors such as these pyramids are far superior to granite or
concrete blocks. When underwater, concrete loses nearly half its
weight and granite loses over a third. Also, the digging properties
of pyramid anchors in mud bottoms increase their holding
power.
