48 North had a good article about a year ago that was titled something like the "The Weenie Route to Southern California" that did a good job of retelling a couple's trip south by hopping from bay to bay all the way down. They waited for weather windows, and ended up with a series of relatively short hops.
I also believe there's a Charlie's
Charts for the Pacific Coast that can help with such a route.
Finally, there's a local sailor who is currently enroute down, using the hop method. His website is
http://www.sailestrella.com/, and so far he's gone from Portland to Newport, Oregon, and may have already moved on to either Coos Bay or Crescent City.
Others, of course, take the offshore route.
Good luck!
