Surprised that you wouldn't use at least 5/16" HT on a NT42.
Also sort of surprised that you could find a 1/4" chain head for a windlass that size.
What size shackles are you using with 1/4" chain? 5/16"? If so the shackle has a breaking strength of 1500# where the chain has a working strength of 1900#. It's ratcheting the overall strength of the rode downward.
The Dashew's use high strength G7 chain on their projects. For example working strength of 1/4" HT is 1900# on G7 it's 3150#. G7 is also expensive.
