Answer A: Why do snowshoes have a hole in the front deck?
I believe key parts of your question concern both the size of the toe hole and the length of the pivoting, clawed sole plate. I suspect that an ideal adult snowshoe would come in different sizes, large, medium and small, say, and that the length of the sole plate and size of hole would be a closer ma...

Answer A: How to explain unexpected success following a bearing taken from an iPad
Let's address what you refer to as "Grid declination". Unfortunately, there are two competing definitions: First, the definition you are conforming to, is that it is the angle from grid north to magnetic north (see NR Can) -- another name for which is grid-magnetic angle. A different definition is...

Question Comparing and combining paddles and pedals for sit-on-top kayak speed and endurance
Sit-on-top kayaks are a popular alternative to traditional sit-inside kayaks. One advantage is that they sometimes come with a foot pedals for propulsion. The foot pedals are linked, via gears, either to a propeller or to flippers. This leaves the hands free for activities like fishing or photography...

Answer A: Why does a manufacturer recommend normal detergent instead of wool detergent?
The folks at Smartwool explain why you should not use fabric softener on Merino wool: Machine-wash on gentle cycle in warm or cool water (avoid hot water as heat may shrink wool). Use mild soap, no bleach or fabric softener (bleach destroys the Merino wool fibers, and fabric softener coats those...

Answer A: Are snow shoes useful in mountaineering?
Yes, snowshoes can be very useful when mountaineering. The ideal conditions for their use are lots of snow and fairly gentle slopes. The deeper the snow, the greater the advantage snowshoes have over just boots. The steeper the slopes, however, the more difficult and dangerous it becomes using snowsh...

Question How to prevent strap slippage through buckle?
A strap running through a buckle is typically easy to loosen and tighten as desired. Usually, it stays in place. Sometimes, however, it slowly (or quickly) works its way loose, as though the thickness or smoothness of the webbing doesn't quite match the size or shape of the buckle. What can I do to m...

Cold-water shock likely ca...

Question How well do mosquito clothing patches work?
They are said to be little patches that simply stick onto clothing, lasting for 12 hours. They are made from "natural ingredients" and DEET-free so I have my doubts. How well do they work?

Answer A: How is elevation gain and change measured for hiking trails?
There are three different ways of describing elevation gain/change for hikes. The least useful &ndash; and sadly a very common &ndash; method is simply to subtract the starting elevation from the ending elevation. This should be called the net elevation gain and mathematically is identical to the s...

Answer A: How common are tandem kayaks?
Tandem kayaks are extremely common. That said, some degree of qualification is needed. Unlike "solo" and "tandem" canoeing, the terms "single" and "double" are used. (They can be abbreviated to S and D -- allowing the D-kayak to also mean "divorce-kayak".) Double sea or touring kayaks are very popu...

Answer A: Is it likely to be my technique or my muscles that cause my arms and shoulders to ache so soon after I start kayaking?
Short of seeing a video of your technique, here is some general advice. A very common but poor technique in the forward stroke is where you keep your torso relatively still and repeatedly push and pull your arms in opposition. It will lead to tired arms sooner or later. Your arms are much weaker tha...

Answer A: Where to buy ethanol in Canada?
Ethanol is usually sold as bio-ethanol in Canada, although, strictly speaking, it is really denatured alcohol (i.e., it has an additive to prevent people from drinking it).

There are four common types of stove alcohol: methanol, ethanol, denatured alcohol, and isopropanol. You can usually find them in hardware stores and (but not always) in camping stores.

Answer A: Reusing disposable water bottles vs. buying dedicated bottles
I reuse "single-use" plastic bottles many, many times. Generally, they do not break. The big advantage of many outdoor-use plastic bottles, however, is that the lid remains tethered to the bottle. So, if there's some risk in losing a lid &ndash; such as when kayaking or backpacking &ndash; I'll use ...

A key part of your question -- "...in its stuff sack..." -- is not addressed here (or in the original, duplicate question).

Answer A: How important is thermal underwear for skiing?
You did not say whether you were going downhill skiing or cross-country. The difference is significant: When downhill skiing you are being carried uphill each time between runs and so are not generating much of your own heat and so are not going to sweat much. You are also never very far from warm s...

Answer A: Can you find your location using the angle between compass bearings?
The problem you describe is known in surveying as three point resection &ndash; essentially you need to observe angles, from an unknown point, between three points whose coordinates are known.

Answer A: Kayaking in the UK
Regarding Q2, a sea kayak might be a little too big and expensive for your needs, as beginners. A recreational kayak -- a bit of a cross between a sea kayak and a whitewater kayak -- is more general-purpose, and is often far less expensive than a sea kayak or a whitewater kayak.
