‘And when he was entered into a boat, his disciples followed him.'
As had previously been pointed out to the would be disciples, those who followed Him must be ready to put all other considerations to one side. And this is now exemplified. Jesus enters the boat and the disciples follow Him (while others accompany them in other boats). He is master of the situation and in total control (in spite of the fact that those who are with Him include experts when it came to boating on the Sea of Galilee). For all recognise His supreme authority. Shortly they would be recognising even more.
An example of the kind of boat used here has been found at the bottom of the Sea of Galilee. It was about twenty six feet (eight metres) in length and probably held about fourteen people, having oars and a mast, and a small platform at the rear which covered a ballast bag, which was probably where Jesus would have laid His head to sleep, because He had nothing else (Matthew 8:20).
