No Rockover:
This image demonstrates extremely poor posture at the catch. The most likely causes of this problem are a lack of flexibility and not executing the rockover correctly off the finish.
It can be corrected to an extent by increasing the feet to seat distance, usually by dropping the feet.

Tense and Raised Shoulders:
Having tense shoulders at the catch makes it difficult to execute a good catch. Encourage the athletes to relax their shoulders and keep them low when coming down the slide into the catch.

Bent arms taking the catch:
Taking the catch with bent arms is generally a weak position and at the catch we want to see the legs engaged with the arms fully extended and relaxed.
Whilst resulting in a slower boat this issue also can cause stress fractures in the upper body due to the overloading caused by the grabbing.
