Certainly, the depth of the water underneath, in front of and to the sides of a diving board is an important safety consideration and hopefully you as a coach teach your divers to always check the depth of any water prior to diving in head first -- especially at new or unfamiliar pools.
With the start of the summer diving season upon us, take a moment to remind your divers again to do this. WHY? Because often times, the diving "well" or "hopper" at summer pools is not as big and not as deep as the pools where your divers train year round. There is a BIG difference between 12 feet of water and 10 feet of water. There is a BIG difference between 17 feet of water and 13 feet of water -- the bottom comes up quickly!!
If your diver is used to practicing in a pool that is 13 feet deep and then they go to their summer swim club where the pool is only 11 feet deep -- they need to be aware of that and they need to make adjustments when they enter the water. Similarly, if your divers go to a diving camp this summer where the water is 17 feet deep and then they come back to your regular practice pool where the water is a very safe 13 feet deep -- your divers must still be VERY CAREFUL until they re-adjust their bearings and get used to the different water depth.
Diving is a VERY SAFE SPORT under supervised conditions and by using a little common sense. Let' s make sure we all enjoy a SAFE summer of diving!!
