Model Observations
Wind speeds are in knots. Arrow size indicates exact speed, color gives approximate speed.
All speeds are for the wind at 10 meters above the surface elevation.

Note: See the big red arrow above?! That's over 25 nautical miles per hour (just under 30mph) and that's the baseline. Now, try sailing a 29' Ericson from Sausalito to just South of Jack London Square in Oakland - out towards Alcatraz, past San Francisco in front of Treasure Island, steady swells the entire time to your back and then under the Bay Bridge and into the safety of the Oakland estuary in the above pictured scenario.

The National Weather Service still has its small craft advisory up with a gale force wind warning from Point Arena to Point Conception in the outer waters.

Cap'n Super Dave piloted the Res Ipsa right through like there was no tomorrow. And there was a couple of times where tomorrow did run across my brain, especially when we saw this as we were leaving the Sausalito channel.
Click on the pic above to see that it is not a tiny sailboat nor is it a larger sailboat underneath a swell. It is in fact the advisory the Coast Guard posted all day long about a sunken vessel in the Sausalito straight. No wonder we didn't see many boats out today.

this blog isn't quite as effective w/o the actual wind chart for that day... which has disappeared... more on that later.

but it really was very, very windy.
