I was a passenger on several Alaska ferries (note correct spelling and word): MVs Columbia, Fairweather (a catamaran), and others. On one, from Homer to Kodiak, the vehicles were driven onto a lift, lowered (or raised, they could do both!), the lift rotated, and you drove off and parked where they told you. You had to BACK onto the lift to get off. SMALL ferry.

Homer, Alaska is as far West as you can drive in continental North America without getting wet (you could drive there from Key West). It's literally the End Of The Road. The last time I was there the End Of The Road was blocked by a Budweiser truck.
