Ferry missing from Portsmouth to Le Havre

The route planner chooses a ferry to Cherbourg and a long drive instead of direct to Le Havre. (Brittany Ferries)

You can force it to use a ferry line by right clicking on it:

But in this case, OpenStreetMap marks the line as 5:45, perhaps that duration is incorrect or too long, thus causing the planner to avoid it? If so you can click on the route near there and select the option to edit on Open Street Map and correct it.
