Andy,
As you would well know, the British Navy had a quant, yet effective habit of
"Keelhauling" miscreants in years gone by.
You know, tie their feet to one end of a rope, loop the rope under the boat
(just like you do with your kite halyard, probably) and tie their hands to
the other end.
>From there you just throw the miscreant overboard, pull him under the boat
for a good backscratch, and Voila(!), one very messed up, very dead seaman.
It doesn't decrease the ship's drag, not unless the poor seaman has knocked
a few barnacles off the bottom on his way past, but it does discourage
members of the crew from doing undesirable things.
It was also a very good way of discouraging the crew from wanting to CHANGE
THE RULES, IF YOU GET MY DRIFT!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Although not impossible these days:

Clive Watts will probably reply to this but I understand that CST are
really into reducing the mast diameter, I think they produced a Contender
mast with 46mm dia! Of course these masts will be heavier...
Proctor on the other hand have gone for an oval section which is a bit
lighter (our mast is really light!)

Lots of variables to play with!
