The Lord went into a boat to teach the people because the crowd was pressing upon Him, and it is very difficult to be heard in such conditions. By being in the boat, he forced all of the people to be in front of Him, and more orderly, so they could hear His mellifluous speech.

There is a spiritual reason why the Lord went into the boat. As so many of His soon to be disciples were fishermen, he was preparing for a great miracle which would firmly impress upon them what their ministry was to be. In His wisdom, he our Lord used the familiar (fish) to call his apostles to a spiritual work they did not as yet understand. This miracle happened very early in Jesus' ministry, as He was assembling His apostles.
