I have dropped a pool 14 inches but not easy
How many inches of the ground can my car be if dropped
On Feb 10 2010 there were 15 inches on the ground.
A metre (anywhere) is 39.37 inches, a yard is 36 inches
The answer would take too long to explain in this forum , I have repaired a pool just like this and i have the pictures to show you what can be done. Call Martin on 301-806-2656 for a complete answer and i could also email you pictures if you want.
Yes, The water doesn't have to be over your head to learn to swim.
