Hi Paul and welcome back to a wonderful world
The last time I fished the Yare it fished best in the evening once the boats had settled down. During the day was a bit hit and miss with mainly small roach appearing, but the evening was a different story with some decent Bream and larger Roach.
Try a little pre-baiting for breakfast, a little shopping for lunch and when the missus is nicely settled, nip out back and fish through the evening
