No, it's intended for water rescue. If one falls overboard and is thrown a rope, this knot allows one to hold onto the rope with one hand and tie a very secure knot with the other.

That's one benefit to the one-handed bowline, also once you do it 2-3 times, you'll realise it is one of the fastest and reliabley holding knots to tie, period.
Yes, I know how to do that. It's the first knot I learned after the square knot. In Poland, it's called: wezel ratownicy (rescue knot). Forgive me, but I've learned everything that I have about yachting in Poland, so some of the vocabulary will be different.

It also goes by "rescue knot" in english and "the king of knots" or simply "the king", or on most the boats I sailed on, it was simply "
the knot", but ya got to be careful there because most knots used by professional search and rescue personel here go by that term of rescue knot and are variations of the bowline (LA City and County fire used to teach the double bowline as their standard "rescue knot" for example, and that made tying the standard bowline a bit of a training no-no).
And best start calling your square knots as reef knots offshore unless you want to be mistaken as a land lover on your first day.
