On Thursday 18 October 2007, Western Washington was hit with a 50+ MPH wind storm.
We had power outages, & my sister said she had a rough
ferry ride from Bainbridge Island to Seattle.

Here are some amazing photos (not taken by me) of the Whidbey Island Mukilteo to Clinton Ferry taken in the same wind storm, from Mukilteo Lighthouse Park. 
These Issaquah 130 Class ferries are over 300 feet long and 78 feet wide and weigh about 2477 tons (4,954,000 lbs) unloaded.

During storms like this the crew plots a course which puts the ferry in the least vulnerable position, but at some point they have to change course, and "come about."  When they did the storm made up for lost time.

After this run the ferry system stopped running at full capacity and ran 1/2 empty for the rest of the night.
Note that there are no longer cars visible in the last shot. I'm sure they were washed into the cars behind them.

Each photo below was taken 0.3 seconds apart (hand held, 320mm).
