Only thing I would say is aim for slack (ish) off St Catherines. If you are going Needles, St Catherines, Bembridge direction hit the needles as the ebb is dying then you pick up the first of the incoming tide as you head for St Catherines which will be smoother.
If you fancy a luchtime anchor then Sandown Bay is nice, as it Whitecliff Bay or head into Bembridge.
Watch out for Bembridge Ledges and Ryde Sands
Keep up posted when you are going, I always enjoy a run around the Island
