48' Monk Motor Yacht 1964

$ 179,000


Is a custom designed motor yacht of renowned shipwright and naval architect, Ed Monk.  She is a perfect example of the extremely comfortable and practical layout along with timeless beauty that Monk is known for.  TOPAZ combines the durability and beauty of teak, mahogany and yellow cedar with the skilled and detailed craftsmanship of her builder.  With four single births, one double birth, two electric heads, a completely tiled shower, and fully equipped galley, the TOPAZ comfortably accommodates six, yet remains a manageable and intimate space for one or two.  The most recent owner devoted nearly 20 years to a major restoration, both inside and out.  Thoughtful upgrades were carefully considered for their quality and longevity. Operating systems and safety features were chosen with sustainable, long range cruising and live aboard capabilities in mind.

You owe it to yourself to view this beautiful yacht!
