any loops that could possibly be used by a front foot are
bad news. If it is meant for the crew's back foot, then the
helm may inadvertently use it with his front foot.
In a pitchpole, the front foot will twist rapidly and is
easily broken.
A rear foot, ideally looped over the toes, and not hard in
will allow the foot to slide out and release as necessary
to prevent you hanging upside down by your ankle.
A rear strap for helm is a great idea, and popluar on
many boats, including '16, but you rarely see a forward
loop anymore.
i know two people who have had footloop mishaps
resulting in plaster - both were forward foot incidents.
