The major issue that tent designers have to deal with is letting
one type of moisture out of
the tent while preventing another type from coming in. The moisture
that we don't want to come in is rain - the moisture that we
want to get rid of is vapour from breathing and perspiration.
The way that tents accomplish this feat is by using a two-layer
system. The actual roof of most tents is a breathable material
which lets out vapour from the inside of the tent. This roof
system is covered by a waterproof fly which is stretched over
the tent to shed rain.

When we are shopping for
a tent we have to keep in mind that manufacturers are often very
optimistic about the number of people who can comfortably sleep
inside their tents. The little diagrams on the tent box which
show the silhouettes of people laying comfortably side-by-side
do not show the flashlights, day packs, spare clothes and Ziploc
bags of toilet paper which invariably end up scattered around
the tent. These capacity ratings should be taken with a grain of
salt. If we need a two-person tent, we should probably buy one
rated for three people. If we want to comfortably sleep three
people, we should buy a four-person tent.
The most common
configurations are dome and A-frame. Both types can be light and
pack down to a compact bundle. The A-frame is sometimes a little
easier to anchor down and therefore more stable in high winds,
but either type will do the trick.
Modern tents are usually
self-supporting, using a system of shock-corded poles which
either slide through pockets in the tent fabric, or fastened to
the tent with plastic clips. Aluminum poles are almost as light
as fiberglass poles, but much stronger. Tents with aluminum
poles are more expensive, though.
We should think twice
about purchasing any tent which is not self-supporting. The thin
soils and rocky terrain of much of Ontario means that it could
be difficult to anchor a tent which relies on pegs to hold it
up. We can replace suspension systems that rely on pegs with
ropes tied to rocks, logs and trees.
When we select a tent, we
are looking at trade-offs between size and weight. Obviously the
bigger the tent we carry, the more weight we will be hauling
along the portage trails, but we don't have to over-compensate
for this. There may be days that we are camp-bound due to bad
weather, and being crammed into a tiny tent too low to sit up in
is a miserable way to spend such a day. We are paddlers not
backpackers, and for the most part our tents are sitting in the
bottom of a canoe or set up on the campsite. A few extra pounds
to lug across a portage is not an unbearable hardship if it
means that we will be comfortable in our tent.
What do we look for in a canoeing tent?
- The fly should completely
cover the tent. Some cheap tents have a partial fly which
only covers the top of the structure. Whatever is not
covered with a fly will eventually drip on us while we
sleep. If there is one part of the tent that we're going to
rub against as we toss and turn, it's the bottom part of the
walls, and this is exactly the part that isn't protected by
a fly on the less-expensive tents.
- We should examine the
location of the door and window and how the fly fits around
them. Will the fly divert water from these openings during a
downpour? A screened door or window isn't going to do much
for us if we can't take advantage of a breeze without water
pouring in.
- How substantial are
the anchor points for guy lines and tent stakes? These loops
take all of the strain exerted by the wind. If they look
like they may tear or pull off, they probably will.
- What is the floor
construction like? In contrast to the tent walls, the floor
should be made of waterproof material. The "tub"
floor, which extends part way up the wall of the tent will
do the best job of keeping out water which may be running
along the ground.
Prices for tents vary considerably, from $100 to $500. As with
any piece of equipment, we get what we pay for. It is best to
buy the highest quality we can afford, but we should never allow
budget to prevent us from hitting the lakes and rivers in our
canoe. I have sat out some severe storms in tents which cost
only $100 and they worked like a charm.
