This year 26 new river ships have been launched to cruise Europe's waterways - a pretty mind-boggling statistic. But wait, there's more. Next year we can expect another bumper collection, including at least another 14 Longships from Viking.
Although some older ships are retired as newer ones come on line, these big numbers tend to conjure up images of river traffic jams, picturesque villages being overwhelmed by shiploads of tourists and ships across the very breadth of the much-travelled Danube.
Should we be worried? Probably not, according to various reports, because no one wants to kill the golden goose by overcrowding and the problems that come with that.
Looking at the issue of ships docking alongside each other, it does happen in busier ports but usually no more than two or three are rafted up together, overnight. Avalon Waterways says the maximum number permitted to raft together is three.
Uniworld's website explains it as follows: "The assignment of the exact berthing is up to the harbour authorities of the port of call, and neither Uniworld nor the captain of the ship has any control or influence over this."
Busier ports also mean ships can't necessarily dock right in the centre of towns, in which case you're bussed to the destinations - but this can happen if there's a problem with water levels or locks and is the norm for shore excursions that are any distance from the city or town anyway.
However, cruise lines are looking at other places to dock, which would increase the tour opportunities for passengers - the only problem is that it takes a lot more time to build a new dock than a new ship, so existing docks in less-visited villages and towns that can be upgraded would be favoured. Staggered departures are more common, so similar itineraries now depart on different days of the week to avoid too many ships arriving at one place at the same time.
Another option, of course, is to choose a river cruise in France, Spain, Italy or Portugal, where fewer cruises operate, although the scene in France is definitely heating up. All the major cruise lines now have itineraries on the Seine, Rhone, Saone and the rivers that run through the Bordeaux wine districts - the Garonne, Gironde and Dordogne.
Most lines offer cruises on the Douro in Portugal and Spain, and Uniworld and Croisi-Europe offer a few on Italy's Po river, focusing on Venice. All of which sound extremely attractive.

When you are flying to the other side of the world to join a cruise, it is a sensible move to book at least one night's accommodation in the departure port city.
You will have a chance to recover from the flight and do a bit of sightseeing, and it also gives you some leeway if there are any delays (no one can foresee volcanic ash, floods and strikes) or luggage has gone astray.
