As a general guide, I dont jump into water less than the height i am jumping from, I bring a rope with 1m marks on it, throw it in with a weight on the end to check depth, then I get in, swim down and check with my own eyes, I dont want to die. If I jump from 5m, I make sure the water is a absolute min 5m deep, the deeper the water the better. I have tried from harbour walls and found the tide very strong, but depth good. I would never try from a pier, they are almost always too high for the depth of water. I would love to add some practical advice to the guide. If you are open to some?

i am also unsure about water depth, there must be a way of working it out, as the only major variables are the jump height and hydrodynamic drag, as all objects regardless of mass accelerate at the same rate.

It’s a very difficult thing to measure. The safest and best way to learn it is through increasing your jump height slowly and getting a feel for what is achievable. I think introducing a scale of jump height to water depth may result in people jumping from too high too quickly. It also leads to ‘assumed safety’ where you think its deep enough but you may not know for sure. If you had a scale you would still need to check the water depth to see if it was safe. Would you trust someone who told you how deep it is?

I’d really like to a ratio of “jump height” to “required water depth”. I appreciate the the hevier the person the deeper the water need to be but a indicator would be very handy.
Good article though.

you need bigger heights.
add me, on facebook or myspace, come for a jump!

You write very well.
