If you don't have a shelter, then you want to find somewhere as safe as possible with solid walls surrounding you, at the core of your building. Garages don't usually fulfil this role, as while yo...
The abilities required are developed through practice and mostly focus on three areas: increasing the oxygenation capability of the body retraining autonomic apnoea responses minimising the metab...
As you mentioned, a vertical sail gives you more power, so where possible that should be your goal, but the drag caused when heeling is enough that for most catamarans you want to minimise it as mu...
If your concern is regarding broaching, then the two actions you take are: allow the head to come towards the wind, reducing the sideways force. This can be instant. if needed, slacken the main, ...
If we exclude the birdwatching explanation Shem gives, the only possible ecological reason for a bird feeder is to counteract the negative effect we have on the bird's habitat by having our house t...
Condensation is usually caused by high humidity combined with a temperature differential. It sounds like you have a very humid atmosphere, which in a tent is added to by the high moisture content o...
One aspect not yet touched on is that for beginner climbers, upper body strength is not actually as important as you might imagine. If we exclude overhangs (which is reasonable for early stages of ...
The three risks that are relevant here are the risk of fire, suffocation and carbon monoxide poisoning I'll take suffocation first. A gas leak can exclude oxygen to the point that you can no longe...
Typically, using 3/4" (19mm) plywood board is strong enough for this use. And the bolts you want are 3/4" (19mm) plus enough each end to screw into the hold and to accept a nut. Bolts used for mos...
The concern here would be if the helmet could move far enough that it doesn't protect your skull adequately. If you can move it significantly I'd want to sort it - remember in an emergency it could...
I swear by Thule for transporting anything on the roof. Over the years I have had various vehicles, and various transport requirements, and this type of bar has: replaceable mounts, so for the ca...
The ocean floor is almost entirely undisturbed by waves - What you are finding comes from the coastal littoral. You can gain some general estimates from direction and strength of storms, but the m...
Once you are past uphauling, it is not a move you are likely to use again. It is a high effort move that in high winds is next to impossible. The moves you will need to learn are: beach start tac...
Here are a few quick and easy ones that will help your strength: Squats will be the most useful. Not exactly at your desk, but you can definitely do it next to your desk. Seated leg raises. Keepi...
The simple answer is yes, you can definitely use waste paper or cardboard to stop an arrow. Various folks have used cardboard boxes, flattened, and piled up to anywhere between 6 and 12 inches thic...
For certain types of hiking, lightness is key. I can't talk for everyone doing that (some may just be unaware of the consequences of their kit choices) but I really like speed hiking / fell running...
This is why most snowboarding and skiing gloves these days have a wiper built in. Rain-X and other coatings can help a little, but there appears to be no all purpose solution, so just get a pair of...
If your reason for not wanting camo is that you want to be obvious (maybe to other hunters so you don't get shot) then you can always flash a backpack with reflective material, or use a hi vis pack...
Paul and Kevin are correct here - any corrective lens has to alter what your eye sees. Your brain very rapidly corrects (a few minutes) but it is a basic function of optical physics that is unavoid...
If you wanted to avoid the 4WD areas* my suggestion would be to make your start point for a multi-day hike at one of the furthest reaches of a 4WD trail. And if that trail is one of the lesser used...
They are examples of a round turn and two half hitches. Sometimes known as an anchor hitch or a fisherman's hitch. http://www.animatedknots.com/roundturn/index.php?Categ=boating A Useful Boati...
Most applications will let you minimise your margins, which reduces waste, then all you do is cut the margin off one page, and then stick that page over the other one, which gives you a solid conne...
Yes - 50lbs draw means you need to be able to pull 50lbs, unless you have a pulley/gear reduction. So if you increase to a higher draw, you'll need to be able to pull it.
It can happen, sure, but because of the way a climbing harness fits (you sit in it) and because of the way falls typically happen (you fall straight down from an upright position in many cases) it ...
My solution to this is a Hohner G3T and a 1 Watt Marshall amp. The Hohner fits easily down the side of my bigger rucksacks, and the amp is tiny. They don't add a huge amount to the weight of my...
