I suppose you could call them daggerboards and they serve the same
function. These ships are flat-bottom freight ships (most of these are
more than a 100 years old) and designed to sail in very shallow water
across the former Zuiderzee and all kind of waterways. They are on the
sides I suppose because otherwise they would take up too much hold
space, and they are easy to manage up and down according to the listing
of the ship.

Yes, he is checking the water depth.

Interesting explanations, especially the second one ;-)
As it happens, during the current competition, at some point two ships
almost rammed each other. The captain of one of the ships jumped on the
other one and started working with his fists :-)
Emotions can soar up quite rapidly during the event.

I have not heard of these here being used as you suggest but plausible.
However, the bottoms being perfectly flat there is no listing when
grounded, on sand banks particularly.

Ah yes! I forgot to mention the ability to make sharp turns using the
leeboards. In the video (and in others) you can see a couple of examples
of that. An important feature too when tacking on canals.
Local television (Omrop Fryslan) is broadcasting the competition here
and there are thrilling examples of fierce turning around a buoy by
several ships at the same time

As I said below: he is constantly checking the water depth indeed.

As a side note it must be said that these ships here have metal hulls.
The change from wood to metal occurred at the end of the 19th century.
