You have been thinking a long time about finding a good used trawler or motor yacht to cruise the ICW and perhaps the Bahamas; it’s been your lifelong dream. But you are new to big boats and think you need to have a better idea of what it will take to maintain her before proceeding.
Relax, we have all had to start from where you are. And in the days before the Internet it was a learn-as-you-go affair; rarely was there anyone around to ask. So to help those of you still contemplating the move, this article is intended to make the process a bit easier.
