"Crochet hitch"

[Hrungnir]

  With a messy mooring knot, you are not only worried, you are also sleepless  ...(You have to be able to easily inspect the knot, from time to time, because weather conditions may deteriorate during the night, etc...)

Yes, I agree that in many cases (not only mooring) a knot which is easily inspected is preferred. I feel a simple hitch like the Two Half Hitches is easily inspected when tied with a bight, and is also proven as a popular mooring hitch.

Small changes like passing the bitter end through the bight (as in the original picture) or more roundturns, seems to add more visual complexity than perhaps a bitter-end-hitch would.

   The problem in this case, with the round turn and the two half hitches, is that, when we tie it with a double line , we can dress the knot in many different ways... ( something reminding the many different ways we can dress the common double eight bend ). Which is the one that can be tied more tightly, and be more secure to the particular type of loadings the mooring lines have to withstand ?
