Planche position engaged just before the catch.
1 Back Somersault
Swing out and back to the platform. As you swing back forwards again, bring your legs up in front of you to quickly get into a Planche position at the frontend before letting go for the catch. This trick is quite similar to a Pelican, hence the alternative name 'Fish-Eagle'.
