Haven't sailed there yet but have been researching west coast
cruising. Seems like it can be challenging. Very few harbors on the whole coast. Harbors in the US NW are mostly rivers where crossing the bar into the river can be quite nasty in a strong onshore wind
looks like fun and lot more places to stay.
I think a lot of it will depend on your schedule and budget
. If you are flush and plan on paying marina bills there are a lot more options than if you plan to anchor
Sorry I can't help at all with the paperword side of things.
I think it will be a great trip and hope I get to do it myself some day.
