Poldo tackle

This ingenious tensioning device has been around in one form or another since at least the

eighteenth century; and is named after Poldo Izzo, an Italian sailing instructor. It can be applied
to a clothesline, a tent guy-line, or in any other situation where a taut line must periodically be
slackened off, then tightened again.

Tie an angler’s loop (see pages 110–111) in one end of a line, which must be at least three times the

length of the required range of movement in the completed tackle (1). Pass the other end through
the knotted eye, leaving a large running loop (2), then make a second loop by passing the working
end through the first loop (3). Tie another angler’s loop (4). To apply tension, pull the two knots
apart; to release it, push them together.
