or cut it with your knife.<<<<<

This is the system George Gronseth advocates (or at least did last I knew).
Release is very simple, the loop is quite oversized, all you have to do is
put your forearm (on the side not over your shoulder) inside the loop in
front of you and sweep the arm up and out ward to take webbing loop off over
your head. Quite simple and quick.

Paddle park cleats and bow u-bolts, sounds like maybe you have a Mariner (or
maybe a Nimbus) kayak. Short quick release towlines are a standard fixture
front and back on most of our sea kayaks (quick release anyhow as long as
you have retied the slip knots once they have shrunk after the first use).
The slip knots keep the line from going through the hole in the cleats but
they pass through easily once the knot is slipped. Simply jerk the slip
knot's loose end and you are free of the tow.

A few more words on towlines. We settled on 3/16" (6mm) nylon solid braided
line because of its strength, easy knotting and its stretchiness. Thinner
line is probably plenty strong for towing at sea but is much more subject to
tangling into a "birds nest" while being deployed and if ones hand slides on
a thin line when it is under tension it much more likely to cut you like a
rudder cable can. Heavier line is bulkier does not stretch as well to absorb
shock. It likely also needs the extra complication (and bulk) of a bungee
shock absorber in the line (when used with a relatively short towline
anyhow). A longer towline should be carried for tows in rough seas but for
most uses a short towline that is handy and can be quickly deployed is all
that is really needed. It is nice to be able to adjust the tow length so the
towed boat can "surf " on the towing boats wake (rather than always be
climbing up a wake wave). If I had to clear a rudder (as the boats yawed
back and forth) I'd probably use George's chest loop system to get the
towing point higher. I have no experience with a body mounted tow system in
rough seas or for long distances but I've towed kayaks for several miles
many times using a boat mounted towline. Not much of a problem other than
slowing me down maybe up to one knot. But you better not be dragging your
fingers in the water back there, I'll know if you are.

If the possibility of being in surf exists I'd avoid towing during that time
unless you can release your tow instantly if necessary. I've tried towing a
swamped boat in through surf with a 3/8" WW throw rope line. After the first
jerk I quickly uncleated the rope from my 5" back deck cleat before the next
wave did the uncleating (of the cleat from my deck) for me. After that quick
lesson I was still able to tow the swamped boat in through the surf by
holding the 3/8 rope in one hand while I paddled. I'd have to circle back to
pick up the (floating) rope again whenever my boat was surfed forward on a
breaker and I had to drop the line. However, the towing by tugging the towed
boat forward (as my right hand pushed the paddle shaft forward) actually
worked better than I thought it would. I wouldn't want to do it for long
distances though.
