A raft would be any flat craft used to traverse over water. If there ever was a need for water transportation in a survival situation, options being scarce, its value you cannot undermine. Capable of transporting you and your equipment over water easier.
These are the survival raft basics for water crossing survival.
Let us first get these things out of the air.
We also have simple and inexpensive flotation/floatation devices, so why not just use them? Perhaps because a raft would be a much safer option although it would require much more work to set up. On a raft, you see, you have the benefit of staying above water. This means the likeliness of getting wet and thus becoming cold is lower. That and a whole lot of other benefits.
Then how about canoes or similar long “vessels, boats”, whatever you want to group them by? Well, a raft generally would be sounder and less quick to capsize because of its square/more even rectangular frame. Plus, a raft even though it still requires a fair bit of skill to build does not come even close to what those long boats need.
With that out of the way, let us focus more now on the “survival raft” as is.
In the jungle, you may find rivers that swell because of seasonal rains. Such conditions would be good for having a raft. But just how do we “have” this raft? Going back to the jungle, you can make a raft using materials you find over there. Under different conditions, the materials available would be different – so be creative.
First, we start with timber. We can get the timber for our raft from either bamboo which would be ideal or uprooted trees of which are sound and unrotted. If ever you are to cut timber, select leaning trees since they are easiest to drop.
In locations with a bit more civilization, you can use objects such as oil drums as means to support your raft.
Traveling By Survival Raft
Be sure to tie all the equipment securely to the raft, or to the safety line. Make sure that nothing nears over the edges where shallows could snag it. For those aboard, they should attach a bowline around their waist. This secured to a safety line or raft.
Key Note: Before you set forth on a journey with your raft, soundly test it first on safe water. Do not gamble with a flimsy raft. Only tough structures will last against mountain rivers with rapids. On wide lower reaches, you will have to swim a long way before reaching the safety of a bank if ever your raft breaks up under you.
