How long does the transit of this tunnel take? Are boats allowed to move through the tunnel under their own power? Thanks for a great video.

No, they are not allowed to move under their own power because of the limited ventilation (the pulling boat is powered by electricity). It's a distance between 5-6 kilometer underground, so more than an hour duration
