Even if you are 200Kg and go for the quoted 500Kg rating that’s still less than 5KN. 1 Nite Ize S-Biner MicroLock Stainless Steel Carbiner The Nite Ize S-Biner MicroLock features 2 gates instead of the 1 you’ll find on climbing biners.

A cheap non-climbing carabiner (at around £3) is typically specified at 10 to 16KN. True, this goes up to 3227N (3.2KN) at 20deg but the cheapest climbing carabiner is rated at over 20KN (note that in climbing that is the breaking load not the SWL as in industrial lifting equipment). Therefor the total tension is 2207N (equivalent to a mass of 225Kg under gravity – hence my basic estimate of a little over twice weight). That means the deceleration creates an additional tension on each side of 1226N (his velocity when hitting the hammock would have been just over 3m/s).
Let’s say said 100Kg bod drops onto his hammock from 500mm above it and the elasticity in the whole thing means it stops falling after 400mm (I think that’s realistic as most of us have ‘fallen’ in and just touched the floor). Now let’s add the load due to sensible dynamics. Example: 100kg bod in a hammock at 30deg: tension = 981N (0.98 KN) on each rope/strap. So, at 30deg that comes out at approximately the same as your weight (though tension is measured in Newtons). The actual calculation for static load is (mass x acceleration)/(2 x sin(A)) where A is your hanging angle. The Gewehr 43/Karabiner 43 joined the ranks of the SVT-40 and M1 Garand as general issue semi-automatic rifles during the war. However, no-one is going to die falling out of a hammock from 40cm (I’m living proof of that but that was due to alcohol ). It was accepted and entered into service as the Gewehr 43, renamed Karabiner 43 in 1944, with production amounting to just over 400,000. I am a chartered engineer qualified to rate systems and loads both static and dynamic and, I apologise, it should have said twice your weight not half your weight.
