If you have spent time around a boat, you know at least a half a dozen types of knots. Those usually are with larger ropes, but the same principles apply.

Knots work because counter tension, build friction – meaning a knot stays snug because there is another layer of rope, fabric or in this case paracord counter acting with tension, the tendency under pressure of most things is to tighten (It's why double knots on sneakers.)

Knowing how to tie a secure knot is a critical skill for the survivalist. A well done knot ensures you can secure your pack, make sure a boat is docked, even secure a makeshift raft's timbers.

In boating a loose knot at best loses your boat; at worst, it can mean something comes loose and that can kill you.

On the next page, we show some simple knots you must learn and master.
