Patrick, sorry you did not come right at Robbin, on Tuesday the fish were active with the pushing tide from about 10 in the morning until just after the the high tide in the afternoon, which is a normal yellowtail thing.
As often happens at Robbin the fish and birds were very shy, and often its only a single sterretjie that indicated the shoals of tail. And you had to approach the shoal very slowly not to put them down. The best approach was to stop up wind of the fish and drift down, takes a bit of patience, but it works. We never saw a fish on the surface, just followed the birds.
You can always see by the way it flies when a sterretjie is over a shoal of tail.
Maybe I'm just getting old, but I enjoy the days like Tuesday were you have to work for you fish, much more than the days I can pull 10 fish in a hour.
