What is a crab?
A crab is a problem encountered by a rower when his or her oar gets stuck in or is grabbed by the water, usually right after the catch or just before the release. The momentum of the shell can overcome the rowers control of the oar. It is caused by improper squaring or feathering of the oar and will happen to everyone who rows. In extreme cases the rower can actually be thrown from the shell, but this rarely happens. Usually the rower will be pushed back and the oar will go over their head.
