Whipping is a specific knot (wrap) used to hold the ends of lines so they don't unravel. It's not made up of half-hitches. Here's a link. As an alternative to whipping, I've used some goop they sell at marine stores that you dip the end of the line into. I'ts like that liquid grip stuff you can dip tools into to form a plastic grip. Stays pliable and soaks into the threads real good.

For whipping here's a link:

: In the current issue of Sea Kayaker there is an article on deck rigging. In
: this article the mention using whipping twine for tying deck lines and
: bungee cords. Well I have tied the whipping with half hitches but do not
: know how to end these knots. Should I coat this with epoxy, varnish or
: fingernail polish to keep the hitches from untying?
