Aquatic park or Sausalito..

Hi guys! I am looking for some advice. I am helping out with some veterans training for their Alcatraz swim tomorrow and they don't start till 10:00 AM in Aquatic Park. I had fished the Sausalito area once from a head boat which seemed pretty relaxed and we caught some stripers and halibut so I was considering finding a launch in Sausalito and doing some fishing, or even parking in Aquatic park to paddle over to Sausalito and then paddle back for the swim. Anything from "that is a bad idea and you will be wasting your time!" to launch suggestions in Sausalito, or areas to fish would be appreciated as I am a self admitted newb to the area!
