STRONG Tides, wind direction against the current and lively seas can present a raft of anchoring problems.
Ground tackle has to be spot-on, otherwise anchors will slip, causing chaos and frustration.
This is a common problem where it is necessary to anchor in sand so craft lay back towards or over wrecks and other bottom structures.
In this scenario, SARCA anchors excel and are superior to grapnel or fluked patterns.
The inverted blade toe is specifically designed to penetrate the sand. The anchor has no prongs, which can foul rope. When this happens, an anchor will drag under pressure.
A semi-circular ring above the blade eliminates this tangling problem and those caused by wind and tide changes when a craft swings 180 degrees at anchor. The ring also acts as a selfrighting system. Ground tackle must be set up correctly with any type of anchor.
The universal rule is to use a section of longlink galvanised chain at least three-fifths of the craft’s length. Pay out a 3:1 rope length to depth ratio in calm, windless conditions. In rougher seas, this might need to be increased beyond 5:1.
