Our route today takes us with the flood tide, north from San Francisco Bay to San Pablo Bay and the Petaluma River entrance. Our goal is to cruise 16 miles up the Petaluma River into downtown Petaluma where we will tie up at the City turning basin. Because the river contains many shallow areas, we'll enter the River on the rising tide, hopefully avoiding any grounding. If we do get stuck, hopefully the rising tide will get the boat floating again.
We exited South Beach by 8:30AM, after quickly re-docking to return the access card keys. Within 10 minutes we were passing under the Bay Bridge headed northward. The course took us along the east edge of SF Bay, east of Alcatraz and Angel Islands, and past the Tiburon Peninsula into San Pablo Strait. Soon we entered and crossed San Pablo Bay arriving at the Petaluma River entrance at half past 11.

The flood tide not only increases the river's depth, but also gives us a speed boost. The boat's 8-knot water speed is boosted to 9+ over the earth's surface, as the tidal current pushes many, many miles upstream. The river's normal outflow direction is reversed by the flood tide. This direction change challenges the levees as the river reaches high water.
Once past the river entrance, the boat towers over the surrounding terrain. With the tide approaching +5 feet, from the boat one actually looks down into the levied fields filled with crops and livestock. Its is a strange view to be above the road height, looking down at cars!
We passed the open Black Point railroad swing-bridge, steered under the Highway 37 bridge, passed the open Haystack railroad bascule-bridge, and drove under the Highway 101 bridge. Today there is light river traffic as we see just a handful of pleasure craft and no commercial vessels. Approaching Petaluma, there's joggers, fisherman, walkers and gawkers on the tops on the levee. At last we arrive downtown at the "D" Street bridge and it's not open, as we're 25 minutes ahead of schedule. Shortly after a our call on VHF Channel 9, the bridge magically opens, we move through thanking the bridge tender as we pass, and enter the Petaluma Downtown turning basin for tie up. A boring 10-minute video with excellent music, documents our 2-hour river cruise at 10 times speed. Enjoy the music.....
