7. Jim’ll fix it:
But if Jim isn’t there, you’ll need to fix it so be prepared with some essential spares. You can never have too many essential spares but some of the most important and easy to carry with you are:
Rope (downhaul off-cut; perfect to tie either around your harness hook or end of boom)
Whistle (unbelievably light and tucks just about anywhere)
Day –glow Flag (folds into any small pocket or stitch it into your harness/buoyancy aid)
