The Eye Splice and its variants are for mooring, tow lines, and other long term or critical applications. Modern synthetic materials, however, tend to be slippery and, now, a minimum of five complete “tucks” is required, seven tucks are recommended. As in weaving, each of the strands is passed first under and then over alternate standing strands. In the process, the free ends tend to untwist and become untidy. Handle each strand with care to retain its original twist: after each strand is threaded, twist it to try to restore its original fimness – at least for the first two or three tucks.
