Crab, or Catch a crab

A rowing error where the rower is unable to timely remove or release the oar blade from the water and the oar blade acts as a brake on the boat until it is removed from the water.

Occasionally, in a severe crab, the oar handle will knock the rower flat and end up behind them, in which case it is referred to as an 'over-the-head crab.'
