How blade depth changes your perceived gearing when rowing

In this video, Lachlan demonstrates how blade depth changes your perceived gearing.
​Most people don't realize that blade depth can have a more significant impact than oar and rigging changes.

So from the comments and my own personal experience, there is such a thing as too deep and this video fails to discuss this problem. Also, it’s important to explain the way in which the blade should be buried. Ie avoiding tension in the shoulders and traps from digging too deep.

If I am used to a shallow connection, would it be better to lower the washers on both sides and use an oar with a slightly higher gearing?

i am confused now, my coach tells me to not go deep, but bury the blade just below the water line.

There is definitely some difference of opinion when it comes to depth. We generally find that our athletes go faster with a little extra depth. Not much, but a fraction more than just below the water line. It's not a necessity tho.

@@DecentRowing Listen to your coach and not the guy in this video. The Sinkovics don't go deep.

Surely there's such a thing as too deep, you wanna be just below the surface no? Also for balance in sweep boats.

I suggest very large and strong scullers can afford to go particularly deep for optimum performance …. Lighter and more nimble folk can go shallow but well covered.
