What strength of carabiners wil be suitable for a hammock seat to make a 65kg driver comfortable, thinking about seat's durability too.
Please answer

Good lord, don't use the ones from the link above. Any carabiner rated for rock climbing will suffice. Run through the calculations yourself, but it's common for basic models to be rated over 20 kN.

The above link was sarcastic because the original post was asking for spoonfeeding. it is very easy to figure out what strength carabiner is needed based on very basic calculations. OP just decided it was easier to ask here than to work for the answer. once a required strength is established by calcs, a very quick google search can be done to find many suitable clips. this competiton is designed to simulate real life design challenges. In industry, one cannot just use what someone else is using simply because they are using it. you must validate your design through your own efforts and prove to yourself that it will work. this competition is about developing the skills that you need to do that.

This is the first time we are using the hammock and I have already done the calculation for carabiners
Just want to know that any TI or Design judges asked for any documentation proof of given load rating of that carabiner..??

You might get called out at tech for not using sound engineering practice if you have no verification of strength. Also, you will probably get railed at Design for the same reason.

if the carabiner doesn't have a load rating stamped on it, or doesnt have a spec sheet, I would rig a few up on a UTM and gather your own data to compare against your design requirements. make sure it is well documented in the case it is asked for. also submit a rules clarification question just in case.
