The Unconscious World of Dream
(1) Because of their connections with water, boats may symbolize (some aspect of) the feminine, either with a plainly sexual reference or with reference to the unconscious (in the case of a male dreamer, the reference may be specifically to the anima). or with reference to mother or Great Mother.
(2) Leaving one's own shores for a foreign country may symbolize entry into the unconscious insofar as the latter is unknown and frightening - alien, in fact.
(3) If the boat is crossing a narrow stretch of water, it may symbolize some type of transition: for example, moving from one phase of life to another, or making a new start and a clean break from the past.
(4) If in the dream you miss the boat, the meaning would seem to be obvious: you have afiled to take advantage of an opportunity that has offered itself - perhaps an opportunity to open new vistas in your life.
