Bicycle Dutch - Watching the Amsterdam ferries (again)

Mark Wagenbuur, from Bicycle Dutch, writes about forever ongoing discussions about building bridges over the IJ, a river that now has seven ferry lines taking passengers back and forth. A quote from the blog:

In the 2015 version, I reported that there were six ferry lines, and now there are seven. The most important one of those, behind Central Station, is the F3 Buiksloterweg ferry. The earliest mention of this ferry dates back to the year 1308, but it is probably much older. Two ships operate on this line during the day, which means a ferry crosses the river every six minutes. During rush hour, a third ferry is added, reducing the waiting time to four minutes. At the busiest times, there is even a fourth ferry in operation.

I was reminded for an incident in January this year when the Metro M52 was closed towards Amsterdam Noord because of a flooding in a tunnel at Sixhavenweg. This was paired with the F3 Buiksloterweg ferries being taken out of service because the platform used to cross when docked had collapsed, the ferries ran to IJplein instead. To make matters works, a number of ferries from the 60 series were taken out of service because of technical problems resulted in cancelling the F9 route between Sporenburg and Zeeburgereiland.
