Bob's questions (>>), followed by Harold's responses (>), followed in turn
by Bob's further comments:

.....It's a very appealing thought to avoid snagging the tow line on the
stern.  I recently experienced (was responsible for) just such a problem
which resulted in a dangerous situation.  Happily, the worst of it turned
out to be my embarrassment, but it could have been nasty for my towees
(there were two hooked up together in a training exercise that nearly went
very wrong).  I can see that attaching the system close to the cockpit might
avoid the alignment problem, but the system seems -- at least as I imagine
it at this point -- pretty cumbersome.  Seems to me that when a tow becomes
necessary, one would want to hook up and get going ASAP.  But, as I envisage
it, you'd have to rig it before you could hook up to the towee.

Bob:>>     3. How would you disconnect quickly in an emergency (say, a
capsize)?
Harold:>3.  Connect the bridle line through two jam cleats, one on each
side, near

Bob:....The disconnect would work well (although you'd want to have a small
supply of spare slip rings handy).  Threading the bridle under the boat gets
back to my previous suggestion that the system might be a bit clumsy in a
situation when you want to hook up to someone in a hurry.  And do you think
the procedure would be practical in rough conditions?  On another point:  if
you make the bridle fairly long, say halfway to the stern, then I believe
you run into that alignment problem, although it would indeed by mitigated
by the slip ring.  For reasons of speed and maneuverability, I think it
would be preferable to learn how to free the tow line from one's stern, and
to learn that it's necessary to check the line at frequent intervals.  Given
my recent experience, I've practiced this and find little hardship in it.

.....Indeed, many boats have these things.

To work through the problems inherent in towing and rescues in general *well
in advance of actual need* is the best way to ensure that they will succeed.
Surely the fouling of the tow line is a serious potential problem and a
workable mechanical solution would be very welcome.  But the mechanics are
not the only factors we need to consider.  I believe that rescue procedures
and equipment solutions should be conceptualized in the context of the
conditions under which they are likely to be needed.  This must include
rough conditions in which the rescuer's abilities and stability may be
compromised.   Accordingly, towing systems must be easy to deploy, easy to
attach, and easy to escape.
