This question is a cause of much speculation, and the answer is very variable at this time.
This morning at the end of my shift at 6 AM the GPS said 350 miles to go, and were were doing 7 knots. This would have us at the Golden Gate Bridge at 8 AM.
But then I woke up around 1 PM and the GPS said 610 miles to go, and we were doing 5 knots. That would have been 5 PM Friday afternoon.
We are now doing 6 knots and have 305 miles to go at 1:30 PM.
The GPS says we will get there in 53 hours. (So like 6:30 PM.)
Hopefully we will get in earlier than that. Noon at the bridge. 2:30 at Fortman?
It would be nice to have some daylight as we go by the Farallons. Should we pass above or below them?
It is my understanding that the wind will be lessening as we get closer to SF, so some engine work may be involved.
