Better still, avoid Chichester Bar at all times by not cutting the corner. Make sure you are south of West Pole on your approach to do so.
Chichester bar
Recently a RIB lost its gear box casing by cutting the corner....
Also, don't cut the corner on the approach to East Head from the Solent as you'll end up on the Winner Bank. Even for a shallow draft vessel, the Green channel markers are very close to unforgiving ground. One yacht on the Winner Bank last weekend (corner cutting), and another the week before (engine failure)
