I'm looking for a guide that can clearly outline the costs involved with owning one of these big 70' Hatteras MY boats. Obviously there will be variables depending on the particular boat, but I figure if the rules are followed, then costs could be somewhat estimated to give prospective new buyers a general idea. I've come across tidbits here and there regarding fuel consumption, and the costs of overhauling or replacing the motors, but nowhere have I seen someone actually break it down in detail. Any insight would e appreciated. Thanks...
