I had my dinghy come unhooked about a dozen times last year due to
exactly this reason. It can happen with any spring latch hook, even
on a jackline if the line gets around it the right way. This is one
of the reasons I was asking about snap shackles.

You might want to look here
http://www.setsail.com/c_central/techtalk/harness.html when thinking
about "biners" for the boat side of the harness. Experience in the
98
Sydney-Hobart showed that drowning can occur if the harness can not
be
released by the wearer. I use a snap shacle on the harness side and
a
biner on the boat side of my tether, but suspect there are better
set-ups.
