I have not spent any time on mapping ferries, so I did not want to pass judgment on these steps. I had previously thought that with time restrictions we could solve ferries with just that feature setting for both segment directions. Separately set toll if present.
I had not considered the other points Panther37 proposed, but many of them make sense. However the parking lot road seems to be a problem and unnecessary since the routing engine will shortly determine the average speed through that area and set the appropriate routing.
If we want to have this info on a separate page, that is fine and if we want to include it anywhere else, we can transclude it as desired.

1. You need to be able to edit AT LEAST both ports. The entire area is preferable.
2. Turn on GPS points. It seems like people like to leave Waze on in the ferry.
3. Draw a road on the ACTUAL path the car would take.
3.1. Have the road right up to the part of the dock where it would load.
3.2. Draw the road using the GPS points to align with the usual path of the ferry in the water.
4. Road type should be "Parking Lot Road" because, ferries are slow. If there is a "High-Speed" ferry, upgrade the road.
5. Make sure the road is a "Toll Road" unless the ferry is free.
6. Don't forget to use time restrictions.
6.1. The first ferry of the day is when it should open.
6.2. The last ferry of the day is when it should close.
