I though a little longer about the load on the reefing block and the answer
is not quite as simple as I wrote. If the reefing line goes though both the
reefing clew and reefing tack (front and back of the reef), the load may be a
little higher.

So you may want to go with a minimum working rating of 500#, rather than
400#, for the reefing turning block. 400# would probably be okay, but I'm
not sure, and as they say in Maine "nuthin too strong never broke".
