"I do not paddle in high winds without my boat leash.
I use two pieces of nylon webbing (one of which is bright red) connected

together in the middle via a cam buckle. This provides a quick release.
Pulling the end of the red strap releases the buckle."

Dan Hagen

How do you attatch the webbing to yourself?  How long is the tether you
use?  How and where do you attatch the tether to what kind of boat?


"Uhhh... (or duhhh..) what's a slip-ring? e"

Elaine,  A slip ring is (in my case) a stainless steel ring that has a
slightly larger inside diameter than the two inch webbing that I use as
a tow belt (worn around my waist and fitted to my pfd).   The tow line
is attatched to the slip ring, the slip ring is slid onto the tow belt,
the tow belt is buckled arround my middle with a quick release buckle.
When I release the quick release buckle the slip ring slides easily off
the free end of the tow belt, releasing the towed object and freeing me
from potential entanglement.

I attach the tether to a web belt at the bottom of my "shorty" PFD,
which is about in the middle of my torso. (This works with my torso
shape; some might need a harness with a keeper strap passing under the
crotch.) The other piece of the tether attaches to a 6mm line that
passes through six pad eyes on the deck of my Caribou. The pad eyes are
laid out in a parallel fashion, three on each side. The line begins with
a stopper knot (at one of the pad eyes furthest from me), passes through
the three pad eyes on one side, across the deck in front of me, and
through the three pad eyes on the other side, ending in another stopper
knot. I don't recall the exact composition of the line, but it has a
braided nylon or polyester sheath and some sort of core material (as
with climbing rope or rescue rope). 

The two pieces of webbing are attached in the middle with a cam buckle,
which provides a quick release. You just need to pull the end of the
strap that passes through the buckle to release it. The advantage of a
cam buckle is that it can be released fairly easily when under tension,
unlike the more common side-clamp buckle, which is extremely difficult
to release when under tension. With my current setup the strap that one
pulls to release the tether is red, but I am planning to replace it with
yellow since yellow is easier to see when it is wet. As for length, I
would estimate that it is about three and a half feet long. (I can't
measure it right now since I am at my vacation home. If you want an
exact measurement e-mail me tomorrow and I will measure it for you.)

Happy paddling!

I have been thinking for some time about boat tethers.  I have tied onto the 
boat at times when I found reason to get out and spend time in the water, but 
have never used one on a continual basis.

One idea that appealed to me was that of attaching the grab loop of the spray 
skirt to a biner clipped onto the front painter, using a nylon strap which is 
wide enough to avoid tangling and a side-release buckle at the grab loop for 
a quick-release.  The presumed advantages are:  1. It would not interfere 
with a forward-roll wet exit;  2. The strap could be easily folded and stored 
on the front deck, where it would be easy to manage;  3. In the water, the 
pull would turn the swimmer toward the boat;  4.  In the event of a strong 
pull from the boat, the skirt would spread the force over a large portion of 
your body;  5.  As the boat drifts downwind / downwave, the biner would slide 
along the painter to the bow of the boat, turning the swimmer's back to the 
waves and the bow into them, decreasing drift and pull against the swimmer 
and allowing the swimmer to tow the boat with a strong backstroke;  6.  Its 
presence would discourage placing the grabloop inside the skirt when the 
going gets tense. 

I would appreciate all your thoughts on this.

Thanks

Harold

This is an interesting idea. The potential drawbacks I see are: (1) The
length of the tether. It would seem to me that using the bow painter as
the tether increases the possibility of a nasty entanglement. That's a
lot of line floating around with you in the water. (2) The use of a
side-release buckle. These do not release well when under tension. (See
my earlier comments on this.) On the other hand, as you noted your idea
does have some advantages.

Dan,

Thanks for your comments.

1.  Using the length of the painter could be a problem.  But I didn't mean to 
imply hooking onto the end of the free painter.  I was talking about clipping 
the biner onto the painter rope while the clip/biner on the (free) end of the 
painter is still clipped onto the boat near the cockpit.  The separation 
between the body and the boat would then be limited by the length of the 
tether (maybe 4 ft?).  Since the tether biner could slide along the length of 
the painter, you would have the freedom of moving anywhere from four feet aft 
of the aft painter attachment point to 4 ft beyond the bow.  You *would* have 
the option of unhooking the painter hook/biner and attaching it directly to 
the tether biner, giving you another 7 to 8 ft of freedom beyond the bow, 
which would be handy if you wanted to swim-tow your boat. 

2.  True, but since the side-release buckle is in front of you, within easy 
reach, you could use one hand to release the tension as you released the 
buckle with the other.  I know that SRBs have drawbacks, but I have started 
to use them in place of other hooks and biners because they are:  (a) 
lightweight (don't sink the towline so quickly when released);  (b) cheap; 
(c) unaffected by saltwater;  (d) unlikely to hook onto deck fittings or 
other catchalls and entrap you as a biner can so easily do; and (e) a bit 
more likely to break in the event of the system being loaded beyond what my 
body might survive (acting as a weak-link).

Happy Paddling,
Harold

Surely none of us uses non-locking biners!

Interesting. That weakness has stopped me from considering using them to
fasten anything, but you have a point. Another thing, however: in cold
water (or with neoprene gloves on) are you going to be able to release it
easily? e

I'm sorry, I simply misunderstood your suggestion. This makes more
sense.

Regarding the use of side-release buckles you wrote:

I certainly have never suggested using a 'biner. The plastic cam buckles
that I use (also referred to as lever buckles) are also lightweight,
cheap, and unaffected by saltwater. I do not believe that they are any
stronger than a side-release buckle. But they are easier to release when
under tension, particularly if you only have one hand free. Your
approach of using one hand to release the tension requires two hands.

Dan, 

Didn't mean to imply you advocate biners in this application.  I was just 
running off at the keyboard. :^)

I've also used plastic cam buckles in certain apps.  Sometimes they slipped, 
sometimes they released too easily, and sometimes they were juuust right!  
Sure wish there were perfect answers to (my) perfectly absurd questions. :^)

Thanks again,

Harold
