Passing through a lock usually needs a fee (by the ship for passenger ships, by the ton for transport ships).

But other than that, ships (with speeds of up to 100 km/h for fast hydrofoils but rarely for the whole trip) are always going to be slower than trains (usually much faster than 100 km/h).

As an example, Vienna-Budapest used to be served by hydrofoil for a 6-hour trip, which takes 2 and a half hours by train. Calais-Dover is also a good example of how train is faster than ship (30 minutes vs 1h30), even in this instance of a very straight route for the ships.

I like taking a boat when I have the option, but it's rarely actually a more practical option than the train. It can be better than a bus though.

Do Calais-Dover ferries sell things on board? I imagine that the ferries in the Baltic Sea have no incentive to cut journey times, because so much of their profits come from getting people to eat, drink, and buy booze on board. Passengers need time to wander through the onboard shops and restaurants.

Yes they've got restaurants and shops and stuff.

And soon, possibly the return of duty free.

That sounds cool, but yes, not competitive unless you are looking for the enjoyment of being on a boat.

More practically, Vienna-Bratislava is 59 or 66 minutes by train, 75 minutes by boat. Depending on your exact departure and destination points, that might actually save a few minutes.

Much of that hydrofoil 6 hours is probably spent at the 5 locks in the Danube along that stretch. And not even in the locks, but waiting your turn for the lock.

So, unless you are looking for a tour of the steel-and-concrete locks of the Danube, the hydrofoil trip may not be for you.
