how to setup a freediving rope part 2 - Marking your freediving training line

Part 2 of ropes and rigging we look at how you can measure out a rope on your own with a small amount of space. for deep lines and competition rope, there is another preferred method for marking however this method is perfectly suitable for lines up to 50m.

Hey Jack, nice videos explaining how to set up a buoy. I’m just about to get my first buoy and got some static rope laying around. The kind of rope used for abseiling, it stretches around 5/10% still a bit but not as much as a climbing rope. Have you got any tips for marking stretchy ropes?
Cheers

While it is not ideal it will still be suitable for use all depends on how deep you plan to go with it as the deep you go the further it could potentially stretch.
instead of the method used in my video another way to do it is to soak the rope for a day then take it somewhere with enough space for the full length of the rope. the idea is to pull out the stretch and make marks while its under full tension
hang one end from a pulley (either a wheel or simple a carabineer ) with a heavy weight attached. try at least double your bottom weight amount
then take the other end and either tie it off to an anchor point in reach or alternatively attach to a car towball and slowly bring it up to tension, some have also used ratchet straps to achieve this.
The weight should always be off the ground when the tension is on. Let it stretch for a bit and dry off then you can measure and make your marks.
this will get you something fairly accurate to work with but i still would prefer to use a more static line (
