“Mr. Mac” is an extremely well outfitted cruising boat. Turn key is an understatement when describing the current state of this Bruce Roberts Seamaster 45. After several years of full time cruising, the owners are ready to move off the boat and allow someone to  pick up where they left off. The boat has been meticulously maintained and upgraded and has very thorough documentation  and descriptions of all work completed throughout the years. From tools, spare parts, as well as full safety gear there is not much the next owner will need to do before dropping the lines to head to any destination they can think of.
