Narrative:

Cleared for visual to sea. Told to fly the bay visual. Captain asked me to set up the ILS for the approach and look up where we were going to park. Captain began configuring for landing and I heard the G/south warning and looked up to see that we were heading for boeing field instead of sea. I directed a go around and about the time we had cleaned up tower called and advised us to go around as it appeared we were landing at boeing field. Took vectors back around for the bay visual and landed at sea. First time into sea for both the captain and first officer. Very clear day and failure to use the available navaids to confirm sea field, were the reasons we missed it.
