Great thread which saves me a lot of typing! I'm adding this to fill it out for more permanent use rather than tag it on the new thread.
Just want to add a few notes about anchorages and pretty routes. Most of our serious Delta cruising was done on a Mainship 430 out of Alameda. So we had to mind a lot of the bridge clearances and opening schedules. My family goes back in the Delta since the very beginnings of its present conformation, so I'm fourth generation. One branch still owns a farm on Ryer Island where we used to go pheasant and goose hunting back in the day. Another great great uncle had a place on Sherman Island for many years where my father spent a lot of time back in the 20's and 30's.
Cache and Prospect sloughs were mentioned in passing.
These have many pretty places to drop the hook and chill out, starting with the little cove just past the ship canal. Since they are not "through streets" so to speak, there is a little more leeway to anchor.
I'll add Sutter Slough and parts of Miner slough to the list.
As a matter of practice, we liked to anchor bow and stern parallel to the levees on one side of the slough, bow pointed up stream. This keeps the boat from swinging into the shore from passing wakes and tide shifts. Being pretty protected wind is usually less of an issue.
More in the tules, but enjoyable, especially with a dinghy, are Potato Slough and White's Slough with varous places to tuck in. An issue that I understand has worsened since our last trips in many of these sloughs can be the water hyacinths. You don't want to be near these at all, no matter what sort of strainer system you have they can clog it pronto. As the saying goes, don't ask me how I know this!
We liked Walnut Grove as a "town" stop, we used Deckhands Marina right across the river near the bridge, not sure if it is still there and under same ownership, but they were very friendly and helpful. It's a pretty easy walk to Locke. I would add Tony's Place right there in WG as a great bar, restaurant and dive to hang out in; we actually preferred it to Al's and Giustis (not in any way saying anything bad about them) as more of a locals kind of place.
Down in Suisun Bay we used to anchor up of Snag Island at the east end of the Suisun Cutoff, across from some lodges on Dutton Island. Picturesque and protected, and a nice stopover if you leave the bay area late, or a nice place for lunch on a day trip. I've taken a Mainship 30 Pilot up to Suisun City, kind of just to say we've done it, something to do once, a winding trip in the ditch, watch the depths. Better to take Montezuma to Hunter's Cut rather than the official entrance channel to Suisun Slough. Speaking of Montezuma, that's another interesting one-timer if your boat fits under the bridge. Plus you get to go through a lock of sorts (actually a salinity barrier).
Petaluma and Napa have been covered; have they finished the new day dock in downtown Napa yet? That was one of our favorite day trips (never took the 430 up there, just a 30 and 34 Pilot and a 390) but you need a designated captain! A flying bridge is great because you go through the Carneros.
I should add, that in my opinion, a flying bridge is great for the entire Delta region, definitely cuts down the "driving in a ditch" syndrome. The 430 and 390 were great boats for that, the only limitation being some fixed or seldom opened bridges.
