It is clear. The circuits are as they always were for gliders - in other words 30 left or 12 right keeping the gliding traffic to the south, with powered traffic always flying their circuit to the north.
Sorry about the obvious error in my last post I of course meant to join the circuit to the north (which would be a crosswind join from Catherine's point).
So from Catherine's Point a crosswind join might be unwise if there is gliding activity and a better alternative would be to stay just offshore and descend directly into the downwind thus remaining clear of Sandown as well but watching for any departing traffic from 12.
Of course the reality is Bembridge and Sandown are sadly very quite these days; keep your eyes out and look out for any sign of gliders out on the grass and you will be fine.
