I took the Coho to Port Angeles for the first time on March 20, 2012 because my flight with Kenmore Air was cancelled due to winds. Even when the BC Ferries aren't sailing, the Coho still sails. The food service is minimal but the seats are comfortable and the views were more interesting for me because you are always seeing land in the distance. The crossing time is one hour and 40 minutes.
I found the whole experience including the security checks to be very efficient and smooth. This is an alternative way to get to Seattle from Vancouver Island even when the weather is bad. I took the 10:30 am sailing and then caught the 1:00 p.m. Dungeness bus to Seattle.
