Single Canoe Self-Recovery
Canoe safety traditions have it that if you go flatwater
canoeing, either you go with other canoes so you can do the
canoe-over-canoe recovery, or you stay within swimming distance
of shore. Of course, we all know violations of these
guidelines are typical. Sometimes lone canoes suffer fatal
accidents as a result, but even multiple canoes can get into
trouble. One outcome of this is that the non-canoeing
public likely regards canoeing as an inherently unsafe
recreation.
So it would seem valuable to investigate deep water, unassisted
canoe recovery. Deep water meaning being out of reach of
shore, and unassisted meaning the presence of only a tandem
canoe, perhaps even a solo canoe.
Canoe literature pays scant attention to spraydecks, and has
nothing to say (that I've seen) about recovering a spraydecked
canoe in deep water. I guess people assume the canoe will
be accompanied and will be de-spraydecked and emptied in
preparation for a canoe-over-canoe recovery. My opinion is
that spraydecks should be regarded as typical canoe equipment,
not something reserved for expeditions and whitewater.
What little advice there is about using a canoe spraydeck
completely fails to recognize that capsizing and recovering a
spraydecked canoe is completely different from an open canoe.
The situation in fact has more in common with capsizing a kayak.
The key factor is that a spraydeck will prevent most water from
invading a capsized and righted canoe.
This, in turn, has two unfamiliar results. The first is that the
capsized canoe will be difficult to right. The second is
that the righted canoe is relatively empty of water and so is
viable for immediate continued travel -- as long as the crew can
get back in.
I have to point out that the scope of our experiments included
only one model of canoe, a total of three people, and a modified
NorthWater spraydeck. The cord lacing on the spraydeck has
been replaced with thick shock cord, which attaches to nylon
hooks bolted to the sides of the canoe. I shouldn't
speculate about how the methods described below would work with
other arrangements, but our spraydeck attaches and detaches in
seconds.
The Capsize
Now, it's plain that sufficiently rough seas can prevent any
recovery. We have tried to find a usable recovery method,
not so that we can blithely go out in storms or open ocean, but
to recover from isolated circumstances. Such as a capsize
resulting from a rogue wave, boat wake, crew error, or a wave
dropping one end of the canoe on a submerged rock. We will rely
on other means to avoid extended threatening situations, such as
watching the weather.
It seems canoeists agree on the observation that spontaneous,
totally unexpected capsizes on flat water just don't happen.
But since we can't control everything, it's important to be
prepared anyway.
I have only capsized in pools. Even that is disorienting
for a few moments. While it's important to brace and know
how to brace to prevent an incipient capsize, things change when
you know you're going over. Keep a hand on the gunnel as
it rises past you. You can use that hand to keep the canoe
from bonking you on the head as it goes over, and it's important
to be holding onto the canoe immediately after the capsize.
Take some time to collect your wits and relax and recover from
the cold shock. Even in cold water, as Dr. Gordon
Giesbrecht points out at this
link, you have time to gather yourself without using up the
time needed to sort things out. Take a minute to calm
down, check on the others, and agree on a course of action.
Even in freezing water, you have at least 10 minutes before
you're too numb to get out of the water, and at least an hour
before you die. On the other hand, panicking because
you're in a big rush to get out of the water NOW, can sabotage
your recovery before it even gets started.
I've read this elsewhere, and will repeat it here: don't worry
about flotsam drifting away. You can retrieve that stuff
later, or do without it. But try to keep hold of your
paddle, and stow it in the canoe as soon as it's upright.
It cannot be overemphasized that these techniques should be
practiced to the point of being drills. Being in a
life-threatening situation is no time to experiment or try to
teach someone else what you're proposing to do about it.
While running these scenarios through my mind the last couple of
years, I was certain some things would work that turned out to
be completely useless, or very difficult. Some things were
easier than expected, while other things were simply not
foreseen.
Righting the Canoe
Again, this is completely different from righting an open
canoe. The good thing is that there will be little water
in the canoe. While practicing this, we could do 3 to 4
capsize/righting cycles before needing to empty the canoe.
The bad thing is that the upside-down canoe has to roll and lift
its weight up over the bulging side of the canoe.
We tried several ways of doing this. The first way is for
the crew to go to the ends of the canoe, and twist on them to
flip the canoe.
Last time we practiced this, I was unable to right the canoe
this way by myself. I know someone who has done this by
himself in waves, and perhaps the waves help. My wife and
I were just barely able to do it. This time, with a
friend, it was almost easy. I don't know if that was
because of improved technique, or a stronger partner, but we
were able to do it easily enough that I would be willing to bet
my life on it.
The second way is a little harder to describe. We
positioned ourselves so that we could each reach under the canoe
and grasp the opposite gunnel. At the same time we lifted
on the adjacent gunnel, we pulled the far gunnel towards us.
Presto, the canoe rolled upright. I was surprised at how
easily we did this, but I'm wary that a loaded canoe might not
come over as easily.
The third way was the easiest. For each of these stages of
the recovery, I wanted to find a method that one person could
accomplish. Partly so that they would be usable by solo
paddlers, and partly so that a recovery would still work in bad
conditions or if your partner was unable to help.
While cogitating about our first evening's attempts, I got the
idea that a strap tied to a thwart, and draped across the bottom
of the inverted canoe could be used to right the canoe. I
mentioned this to a friend who has been a river raft guide, and
is a CRCA instructor. He immediately said: "Yes,
absolutely, it will work." He added that this is how
river rafts are righted.
So I made up a strap and tried it in the pool. The canoe
righted so easily it wasn't funny. Actually, it was funny.
It took seconds, and worked whether I started with my feet
against the side of the canoe, or just pulled on the strap.
The latter was a failed attempt to get on top of the inverted
canoe by using the strap. The canoe righted before I came
anywhere near getting on top of it. It worked whether the
strap was tied to the center yoke, or one of the mid-point
thwarts.
I used tubular climbing webbing for the strap. It needs to
be only about 4 feet long. Doubled, with simple knots
gives both loops and the knots to aid as your hands get stiff.
I found it very easy to grip. We will keep it attached to
a thwart and bundled up under the side of the spraydeck.
There was a method of righting the canoe that utterly failed.
I inserted a double paddle between the spraydeck and both
gunnels, and attempted to use it as a lever. No way could
I get enough leverage on it to do anything. Maybe it would
work with two people, but since the other methods worked so
well, there's no sense pursuing it.
Reentry
Ok, the canoe is upright, and there's less than an inch of
water in it. Now for the tricky part.
The first thing we tried was for one swimmer to hold a gunnel,
and the other person climb in. This worked surprisingly
well, but the other person did it much more easily than I did.
He is a lot stronger than I am, but was wearing a wetsuit rather
than a pfd. Last time, my wife was unable to do this.
So this ability will vary considerably from person to person.
If the gunnel submerged, the spraydeck kept water out of the
canoe.
Next it was time for the second person to climb in. We
were able to do this by having the person already in the canoe
lean far to the opposite side of the person reentering.
Once, our timing was off and we rolled on over. I suspect
a loaded canoe would be less skittish. This seemed simple enough
that I wondered why I had thought it couldn't be done.
Exactly how you reenter is an issue. It's best to reenter
at the center, where the canoe has the most stability from
width. But it's also too far to reach the far gunnel.
An important disadvantage of the spraydeck is that it covers the
thwarts you could otherwise grab to haul yourself across the
boat. It might be worth attaching webbing handgrips across
the width of the spraydeck.
Another important thing to point out is that you should be
horizontal in the water before initiating reentry. This
means you have less of your body to lift, and will not be trying
to somehow haul your folded body over the gunnel.
There are several ways to get horizontal. Obviously one
way is to kick your legs to the surface behind you. Being
on the windward side of a boat being blown downwind will help
this. Another way is to hook a leg into the cockpit, and
shift your weight onto the canoe until you can reach the far
gunnel. There's another way, but I'll get to that soon.
I've had a lot to say in the past about using a paddlefloat, and
we always carry one on deep water trips, alone or not.
Ours is made of two Mohawk paddles that clip together like a big
kayak paddle. We have clip-on T-grips to convert them to
spare regular paddles, and a kayak paddlefloat that goes on one
blade.
Last time we tried this, we found it hardly worked because the
assembly was not securely attached to the canoe. I rigged
up some straps, but still found the arrangement came apart too
easily. Better was having the paddle inserted between the
spraydeck and the gunnel on both sides of the canoe, but it
still wasn't good enough. I think an additional paddle
pocket on the spraydeck is needed, plus some sort of strap for
the handle.
Our first paddlefloat was a cheap kayak paddle with a stuff sack
containing a chunk of styrofoam attached to one end. Now
we have the Mohawk, and a real NorthWater paddlefloat. In
one way, the homemade version was better. The stuffsack
would fill out with water, and the resulting weight would help
keep the canoe from capsizing to the side away from the float.
The latest paddlefloats have a water pocket for this purpose.
I was able to reenter the unoccupied canoe unassisted using the
paddlefloat, but it was more difficult than with someone holding
the other side of the canoe. It was not hard to sink the
float. I suspect it just needs more practice, but it can
be done.
I tried attaching a webbing stirrup to the shaft of the
paddlefloat, but this mostly succeeded in dislodging the paddle.
Attaching the stirrup to a thwart was far more stable and made a
"vertical" reentry easier, but not much.
Initiating reentry from a horizontal position works better, and
there's no use for a stirrup then.
Reentering the canoe with the paddlefloat, and someone else
already in it counterbalancing me, was better. Then I
discovered that if I hooked an ankle over the shaft of the
paddlefloat, it was even easier to get back in the canoe.
The paddlefloat meant that in an emergency, we would be that
much more stable to regain our positions, bail, etc.
Where you get back in the canoe is something to consider.
With an empty but spraydecked canoe, it might be best to open a
center hatch (if so equipped), and get in there because you're
using the width of the canoe. But once there, you probably
still need to get to your seat. Probably this is best for
the first person, to keep the canoe trimmed better. The
second person can reboard at their seat. For a loaded
canoe, a center boarder will end up atop the baggage, raising
the center of gravity. As mentioned before, we suspect
reentry would be easier with a load due to the canoe having more
inertia and riding lower.
We didn't test reentering over an end of the canoe.
Upside Down Paddling
Since the capsized, decked canoe has so much initial
stability, it would seem logical it could be used to advantage.
A friend extricated himself from a capsize in ocean surf by
mounting the inverted canoe and paddling it to safety.
Well, I don't know how he did it. I could not get on top
of the capsized canoe. The other fellow succeeded, but it
immediately rolled him off. Verdict: not a reliable
technique.
PFD's
I have speculated that movements such as reentering a canoe
work better if your pfd is propery positioned on your trunk.
My pfd is a reasonably decent one, but despite not being
overweight and having plenty of time to fuss with it, I was
unable to keep it from riding far up on my chest during this
practice. Unless one has the priviledge of a waist size
somewhat smaller than one's chest, I don't see what's to keep a
pfd without a crotch strap from riding up, no matter how tight
it is. You're asking something to slide the wrong way on a
cone. On the other hand, pear-shaped bodies should float
better and stay warmer in the water.
Chotas
Chota boots have been promoted by many, including myself, as
the cat's ass canoe/kayak boots. One thing not mentioned
about them so far, is how they perform in a capsize. For
some of the testing, I donned my knee-high, neoprene Chota
mukluks.
Your first dunking with them is an eye-opener. Being
neoprene, they float. But there's another consideration.
The well-designed top strap and seal means there is air trapped
inside. The skinnier your lower leg, the more air.
This is a pretty significant amount of flotation, and when you
enter the water, your feet zoom to the surface. Depending
on what you want to do, this can be a curse or a blessing.
I'd hate to be in this situation without a pfd to float the
upper body.
For instance, to reenter the canoe, you want to be facing down,
with your body horizontal. But the favoured resting
position for someone wearing a pfd and "inflated"
Chotas, is on your back with your feet at the surface in front
of you. It is difficult to change to the desired position.
This effect can interfere with swimming, and the easiest way to
deal with it would seem to be to let your legs float out behind
you and paddle with your hands.
Fortunately, as you struggle to get your feet where you want
them, they will go deep enough that water pressure will force
the air out of the boots. That leaves you with the
flotation only of the neoprene, which is enough to be helpful
but not a nuisance. Some water will get into them, but not
a whole lot, and you don't notice it until you leave the water.
I got about a cupful in each of mine over a half hour of
submersion.
One thing we didn't test was removing the boots while in the
water.
Lastly on the Chotas: entrapment. Our canoe has very low
seats. I tried kneeling, which requires the boots be under
the seat. They were so jammed under there that I was not
willing to even test a capsize in the safety of a swimming pool.
I know that in the past I've claimed this is a theoretical
problem only, with no known fatalities resulting from it, but
after this test I won't be poo-pooing that concern any more.
In Conclusion
I'm aware that these methods involve more "gizmos",
and in emergencies you don't want to be fussing around with
stuff. But the techniques do work, and I believe that
sorting them out greatly expands the safety envelope.
Then there's politics. I'm free to experiment and advocate
such things because I have little vested interest in the canoe
scene's status quo. Some will simply ignore these ideas.
Some will just respond that novices shouldn't use spraydecks,
stay out of danger, and not go out alone.
Some will claim that adoption of the methods will cause
beginners to venture to their demise due to misplaced faith in
the promise of safety from the ideas. I don't buy that.
While that is one consequence of any safety advance, like pfd's,
the advantages to the sensible far outweigh the lure to the
dumb. What I would like to see is for highly respected
canoeists try out these methods, hopefully agree on their value,
and endorse them within the sport.
Embracing such methods would not only make canoeing more
appealing to gear junkies, but could help advance an image of
canoeing being inherently safe. I'm afraid it sounds
grandiose, but I do believe these methods could save lives and
widen the appeal of canoeing.
So all in all, we were quite pleased with the session, which we
crammed into one hour. It took place at UBC's awesome
more-than-Olympic standard pool, where, due to peculiar
circumstances, we had the vast pool to ourselves with no
spectators or staff. We will do another session some time,
just to refine the moves, and my wife needs to learn them.
We're also not sure yet whether the more agile person should be
the first or second to reboard the canoe.
