I can't take any credit for already knowing this, all my information comes from an article from Penn State University, entitled Deer-Forest Study: The eyes have it! Some of the information in this...
Like you said, there are probably a hundred classes of adhesives available today, each one totally unsuitable for the things the others excel at. So we need to take a diagnostic approach here. Yo...
Yes, pretty much every Inflatable PFD is designed like this. To give some indication, have a look at this model: Mustang Elite 38 and its owner's manual. (Note: this answer is not intended to be ...
I didn't intend to self-answer, but after hours of 'net searching I seem to have stumbled on the answer, provided by an Olympic Gold Medalist sailor from Australia, so I hope we can trust it. You ...
The other day, this question (Why did wetting down canvas sails increase the speed of a sailing ship?) was asked regarding the historical practice of wetting down sails. The current answer quotes ...
First, a note on terminology. There are several groups of knots that have a certain what I call topology. When that topology in the rope is tied around a fixed object, the resulting knot has one ...
One thing not yet mentioned is quickness and ease of rescue. In my younger years, I was a trained lifeguard, and though my certification is long expired, I remember most of the concepts. A strugg...
This answer applies only to signal mirrors which are two-sided and have an aiming hole in the middle, which should be the case with any good signal mirror. My answer will partially duplicate a pri...
Burn an ordinary paraffin candle. There are several claims floating around that describe how some well-intentioned people are actually increasing their total CO2 emissions, by turning off their el...
If you imagine cutting a canoe or kayak along each axial plane, you get three shapes. If you cut along the waterline and look down from above, you get the plan. Cut thwart-wise at the widest poi...
To expand on an earlier answer, and what the OP himself mentions, I will add a few more elements. First, the count of persons on the trip. The rescuers need to know when they are done. If they'v...
Eventually some part of your brain is going to start thinking, "Holy (expletive), Rattlesnake! I'm gonna loose an extremity! I'm gonna die! What's going to happen to my family? Why did I even co...
You don't need a compass, nor any mechanical tool at all. You just need your fingers. I've linked an article with illustrations at the end, but here is the basic idea: Stand facing the sun, ext...
You need something else. You need a sextant and a marine chronometer (a fancy watch). The sextant measures the inclination of a star or the sun, and helps to determine latitude. Once you know tha...
I currently live about 25 miles northeast of Cincinnati, Ohio, USA. On February 20-21, 2015, a fairly significant snow and ice event struck the area. On February 29-March 1, 2016, a smaller event...
The OP provides an nicely detailed self answer, but I would like to add that when such areas exist, they are of particular concern to mariners1, and are therefore well-documented for nautical navig...
Based on the comments, it seems that you are looking for some sort of fabric that has moisture wicking capabilities. There are several fabrics that have this desirable trait. Many of them are syn...
My answer is that as soon as a thing begins being thought of, even potentially, as being involved in a sailing craft, it takes on the sailing term. If I am going to the hardware store to buy somet...
I've been geocaching for 12 or 13 years. I'm no power cacher, but I do have a few hundred finds. But you know what? I also have a couple hundred no finds. Some may have been missing at the time...
Let's please begin with the understanding that I have already sought and received professional medical advice. Also, about two weeks have passed, my heart and lungs still work and nothing has turn...
I found these structures while hiking in Wayne Township, Clermont County, Ohio, USA, on June 7, 2016, at approximately N 39° 12.5 W 084° 04.0. I only had my phone, and not a real camera, so sorry ...
There is already an answer that gives the basics, and this official page from the Coast Guard adds several details, so here is my summary. The system of ratings for Personal Flotation Devices (PFD...
It seems like you simply need to reverse the procedure you give. Since you initially had to pull the rope up far enough to tie the stick in to it, you can still pull it back up to the same point i...
To get the complete answer, you would need to study up on your Navigation Rules, International and Inland, also known as NAVRULES and as the 1972 COLREGS (Collision Regulations). This book is the ...
