That a sailboard sinks when becalmed is not germane to
the fact that it is still a vessel. It is a vessel because it
has a sail attached that moves it along on the water when
the wind comes up. A kite board has no such sail attached.
In the same manner a water ski has no such propulsion of
any kind attached. Neither is a vessel. The only way either
of them stay on the water is when being dragged along by
an outside force that is not even applied directly to them.

So the fact that it sinks when becalmed is irrelevant?

Yes, because the sails are attached directly to the board.
Even small (sinker) boards are sailboats because the sail
is attached to them and can power them fast enough to
stay on the surface and go from place to place.

A windsurfer is a small sailboat.

You are clearly wrong. A kite board sinks when the
operator stands on it. A water ski also sinks when
the operator stands on it. Clearly neither is a vessel.

A barge floats when cargo or people are on it. Even if
it has no power it can drift from place to place with
the winds and current. A barge clearly is a vessel.
