Sorry for the delay – only just noticed the add on question…

As for the shank, straight into the anchor locker no problems.
The anchor does sit quite high on the bow roller though and as such any straight locking pins will not slip though.
I guess either a not rigid fixing or a another hole will need to be drilled through the shank.

Another word of warning is that if you have or intend to fit a bowsprit / prodder the oversize anchor head may get in the way!
