In which sport can you 'catch a crab'?

In competitive rowing, there are specialized terms that are important in the corresponding aspects of the sport.

One such term is: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. This results in slowing the boat down. A severe crab can even eject a rower from the shell or capsize the boat (unlikely except in small boats). Occasionally, in a severe crab, the oar handle will knock the rower flat and end up behind him/her, in which case it is referred to as an 'over-the-head crab.'
