Hope those using the bay are prepared for this, especially when your chasing pelagics around the bay, or just traversing the channels or paddock enroute, st helenas not much problem, but the big green square in the middle has certainly grown from what it was supposed to be.
The squares shown below are roughly according to their gps zones what the size of the area is.
I hope they have plenty of patrolling authorities out their when it comes into force.
