12 ROLLING HITCH AROUND A SPAR
A slightly different form of Rolling Hitch from the basic one described already is
used when securing a rope to a spar rather than to another rope. In this case the
initial turns do not cross over each other, they simply roll around the spar. The
final Half Hitch is still formed beyond the point where the standing part of the
line meets the spar.
