Just to let you know, there is a 3-day Princess cruise this fall that will spend most of the day 60 miles off Oregon and central California in daylight hours. The Golden Princess has a walk-around bow for unobstructed forward seabird viewing on the Promenade deck. Interior rooms from $249 per person double occupancy (plus $70 tax).
Good possibility for Cook's Petrel, perhaps Hawaiian Petrel, Scripps's Murrelet, other rarities and common seabirds and marine mammals.
I don't think I'll be attending, and I've got to renew my passport, too. Perhaps the perfect get-away for some deep water pelagic birds and a non-birding spouse? You are on your own if you decide to go, but I wouldn't be surprised if there are other West Coast birders on board.
More info on the Princess Cruise line page.
More info from this blog on birding on cruise liners off the West Coast.
p.s. The Golden Princess has better viewing on the bow than Coral Princess. Both ships make the same cruise that same week. Other ships make a 2-day run from Vancouver to San Francisco. Look for the covered walk-around promenade deck on the bow. Otherwise you'll be forced to watch birds only from one side of the ship, not the front.
