I don't recall having as strong of tides in Richardson bay, though, the afternoon winds can be strong. We always stayed in Schoonmaker's marina.
More on mooring balls in Ayala:
I use my long 300'er to grab the up current ball, then I back down to the other. Even so, I find it easier when there are no currents. I have my wife keep the bow line from getting under the boat. You don't want to foul a prop in the cove.
If you have spring tides, you have an entirely different game. You'll be lucky to get you bow line on the ball. If you're struggling, I suggest letting it swing from the bow, while you launch your dinghy. Another way to do it would be to use the day use dock until the tides ease up.
On one trip to Ayala cove, we had a fair current running. I pulled up near a mooring ball. I grabbed the ball with the boat hook and drew it close to the stern. Just when I was ready to loop the line through, the boat took off, I was holding on with all my might, but myself, the hook and ball were stretching. WHen I felt I couldn't hold on any longer, I let the hook go. I shot across the mooring field like an arrow. The surrounding boaters all clapped. So, watch those tide charts. Pick your hour.
On my last trip, I saw a fisherman tie a single line between the balls. This single line was loose enough for him to tie to his bow and stern cleat. I suppose it worked if you had only one line. It would be a pain to untie in the morning.
This guy fell off his bow, trying to reach the ball:
