Rope ends made of synthetic fibre are usually not tied off with a whipping knot, but by melting
with a special rigging heat-cutter
(SVB no. 12015), by dipping into liquid rope whipping
(STAR BRITE Dip-it Whip-it SVB no. 61140), with self-welding tape
or with heat shrink tubing
(GLEISTEIN Heat Shrink Tubing SVB no. 55053).
