I would go south down Steamboat Slough and take the Sacramento River north to Old Sac. You can also go North on Steamboat Slough to the Sacramento River, but I have never tried it so I'm not sure how many no wake zones there are. Old Sac has public docks next to the Delta King. Check out www.californiadelta.org for lodging, tide charts, maps & other good info. Also check out the www.boatered.com/forum/forum.asp?FORUM_ID=68 forum. Pier 39 is always a good time, weather shouldn't be an issue. If you're not familiar with the delta a GPS is a good idea.
