If it sinks, it could get entangled on stuff you can't see and you'll
lose your tow rope.   Or the snag will result in two boats in trouble.
WW paddlers always prefer floating rope for these reasons.

One thing - a little off topic - that I've been thinking about the past
couple of days is: how strong should the tow rope be?  New rules
in Canada require "buoyany heaving lines" at least 15 metres long
on all kayaks.  I've checked the web site Philip has pointed us to
and can't find anything on how sustantial the heaving line should
be.  WW paddlers usually use 450 kg (1000 lb) static load for
rescue ropes and most tow ropes I've seen are about 225 - 300
kg (500-650 lb approx).  On the other hand, I don't think I want to
handle more than 100 kg* tension unless I'm on land with a
solid object to attach to.  Light line is murder on the hands, heavy
line is easier to pull, but won't break until after it's damaged you.
I've thought of, say, 250 kg line with a weak point on the tow
system of 100 kg capacity.  That way under tow it will limit
its effect on me but the basic line strength is there when I need
it.

*100 kg allows for some reserve for impact loading.  When paddling
a kayak that's still a _lot_ of force.
