How can I stop missing water at the catch?

Isn't the simple answer not to push off the stretcher until the blades are adequately immersed?

So one of the things that I have been using the Dynamic Indoor Rower to work on is being less hurried as I come up the slides. To quote Harry Mahon, “It is the ability to be poised forward on the front of the slides before the blade is in the water that allows us maximum efficiency. There is a point when you don’t have to do anything except make sure that you are connected.”

Rushing the Slide is a common rowing technique error. “Moving too quickly toward the catch will prevent you from having an efficient rhythm and causes ineffective rowing. Give yourself time in the recovery to breath and set up the right positions for the work of the drive.”
