Can you picture yourself drifting on the smooth waters of a sunny harbor in your very own boat? If so, you may be ready to buy that boat and make your vision a reality.  Calm and rational thought, however, should dictate your decision. For most people, buying any boat larger than a canoe is a major investment that requires thought, research, and planning. You can easily spend more on a boat than a car. The steps to follow in deciding to buy a boat are the same steps you follow for any major purchase. Start by assessing your needs.
