As you peruse thru this listing you will realize how much effort has been spent to make this vessel special and one of a kind.  A truly custom yacht.  She has been maintained to the highest standards regardless of the cost by the original owner.  During the past 2 years the following upgrades and changes have been made: New appliances, electronics have been updated, including Flir night vision, all exterior cushions have been replaced, also new weather covers, all new Fabrica carpets installed thru out the vessel and complete new teak decks. The owner just doesn't have the time to enjoy her as much as they would like.  Consideration will be taken for, possible smaller trade and all offers will be considered. 


Sleeps eleven in FIVE beautifully appointed ensuite Staterooms.  Layout includes a stunning on deck master separately located from all other guests suites on the forward main deck with a panoramic 270° forward view.  The four spacious guest suites are all located on the lower deck. All guest staterooms are ensuite, complete with updated flat screen TV's, separate SAT receivers (North America and South America),  stereo systems, telephones etc.  The VIP is as large or larger than most masters of a yacht this size, a great plus for chartering, or accommodating family or friends.  Aft is a large completely separate crew quarters for Captain and a crew of three.  Four berths total, the crew enters thru a port side exterior aft door or thru an entrance on the transom.


The vessel can be boarded by using two forward or aft boarding gates, port or starboard side. Also boarding aft via the swim platform and up either port or starboard teak steps to the protected aft deck in which you can then enter the main salon thru automatic opening stainless steel air doors.  From the aft deck because of her wide beam (23.6’) are port and starboard protected wide safe walk around side decks going forward to the bow with entry doors both port and starboard.  The complete main deck is teak.


From the aft deck by a push of a button, (or can be set automatically) two stainless steel glass doors open simultaneously to the wide open space of the Main Salon.  Fabulous large dark tinted windows, port and starboard with custom made woven sandalwood twig blinds surround the Salon, a large center sycamore ceiling soffit with hidden indirect LED lighting gives of a nice soft glow throughout the entire room.  To port is a custom sofa with coffee table, and two leather barrel chairs facing the starboard side for viewing the large pop-up flat screen TV.  The forward part of the Salon hosts the salon bar fronted with real bone tile and is topped with back painted glass, with four leather stools.  The bar stands in front of a back- lit wine library display flanked by two back lit floor to ceiling Lalique French crystal panels.  The wet bar is fully equipped with new U-Line Fridge, icemaker, wine cooler, s/s sink, a marble counter, and a frosted glass top.  Felt-lined Custom cabinets for Liqueur, crystal and glass storage are located in this area.

The Salon has a complete state of the art entertainment system with Bose surround sound and hidden speakers, I-pad docking system, receivers and DVD/CD system, and a new 49" SONY HD4D Flat TV.

The dining area is integrated into the Main Salon at the aft starboard corner.  A beautiful custom glass dining table accommodates newly reupholstered 8 dining chairs.  There are also built in cabinets port and starboard for lots of storage for dishes, cups, saucers and cutlery etc.  All the furniture is custom but not built in and removable.

Master/Day Head

Walking forward thru the Salon, you will enter on the starboard side thru a granite soled foyer; to port is a day head featuring a granite counter top, glass vessel sink above the counter and vanity below.  The walls are covered with a silk wallcovering accentuated with thin strips of sycamore.  The floor is marble with embedded circles of onyx.  Walking forward of the day head thru a privacy door you will enter one of the main features of this yacht, which is a luxurious split level owner suite, usually found on much larger vessels.  The main deck Master enjoys complete privacy, as all other staterooms are on the lower deck.  With 270° forward views, from your island King master berth you can also view a 42" SONY 4K flat screen TV that will pop up as desired.  Features include: Custom cabinets with built in vanities port and starboard, built in drawers on each side of the king bed, also a built-in small beverage cooler and an owners' safe. 

Forward of the TV is the stunning lower level Master bathroom.  Entering down a shallow sweeping marble staircase you will find a half moon his and hers vanity complete with marble counter tops, full wrap around mirrors with concealed lighting, nice his & hers deep sinks and custom cabinetry lined with stunning real mother of pearl insets throughout.  Port and starboard are his and hers cedar line closets, a large tubular shower to starboard and toilet room to port.

Upper Deck / Flybridge

The open flowing upper bridge is HUGE!  Whether dining, entertaining or just plain relaxing in the sun, or in the shade enjoying a cool breeze under the protective hard top this deck has it all.  This deck is custom built (you won't see another like it).  Appointments include Jacuzzi, starboard side settee, complete entertainment system with Bose speakers, I-pad dock including protected flat screen TV with Satellite that pops down out of the hardtop ,sun pad, fully equipped wet bar with four polished stainless steel stools, forward protected teak dining table with teak deck chairs, huge aft wrap around settee with two Santa Barbara mahogany shade umbrellas, sunpads, chaise lounges etc.  The upper deck has new teak decks, and a complete steering station with all state of the art electronics, four captain’s chairs two to port as well as two to starboard, a great place to sit while cruising.  A clear vinyl enclosure keeps the rain and cold breezes away. There are Sunbrella covers that protect all chairs, tables, bar, settees, jacuzzi etc. 

Lower Aft Deck

The lower aft deck is another great spot for dining or relaxing.  It has a built in settee that wraps around the transom.  In front of the settee is a large teak dining table that can slide forward and   aft for easy seating.  There are also 3 loose teak deck chairs  This table can seat approximately ten guests.  The deck is teak and is protected with a full hard top overhang.  All ceiling lights can be operated with dimmers.  Also a 20” flat screen TV that drops down from the ceiling ,complete sound system with Bose ceiling speakers.  There are two back down stations (port and starboard) with full rudder, transmission, and engine controls, also two electric capstans for easy docking and line handling.  You may enter the aft deck on either side of the vessel (locking boarding doors), or from the swim platform as there are teak boarding steps on either side of the transom.  A wide teak staircase with stainless steel hand rail on the port side will guide you to the upper deck/flybridge.  The lower deck has lots of storage.  On each side of the sliding polished stainless steel doors there are two small shoe lockers, as well as the transom settee has storage under the seats.

Swim Platform

This vessel has an extended swim platform that can accommodate a 16' tender or twin Jet skis. The tender is launched by a updated 1600 lb. Quicklift hydraulic davit, concealed in the transom.  By a push of a button a hydraulic door opens the top of the transom, and the arm of the davit controlled by a hand held remote swings out, and easily launches the tender.  The polished stainless steel tender chocks are removable and makes the extended swim platform another great place to play once the tender is launched!  This system is easy as the tender is close to the water, but best of all it saves a tremendous amount of space and effort as the davit and tender are not sitting up on the upper deck.

Crew Quarters

Crew quarters can be entered thru the main deck port side aft door or the transom door meaning the crew does not have to enter the interior of the yacht.  The crew has a galley area with microwave, Subzero Fridge and freezer drawers.  Three cabins, one is ensuite for Captain with full size berth.  The other two cabins have a total of 3 bunks. They are separated with a full bathroom and shower that both staterooms share. There is also a second washer and dryer and Captain's safe.

This Johnson 103 is by far the Queen of the Johnson fleet.  With her strong unique styling, designed by International Award winning Naval Architect Bill Dixon of Dixon Yacht Designs.  With the expertise of her owners and Interior Designers, Trevor James & Studio of New York, the impeccable interior, and unique upper deck layout was developed.

Both interior and exterior social areas allow for tremendous flexibility in entertaining, by well thought out functional zoning.  People viewing the vessel have often been surprised that the yacht is not larger than its length of 103'.

The rich interior has light hand-picked configured sycamore with a full high gloss Varnish, and only the best fabrics were chosen, stunning Lalique crystal panels along with other glass work, combined with teak, marble, and granite, onyx, bone, mother of pearl, silk, and fine leather compliment the surrounding custom cabinetry throughout the vessel.

She has been maintained to the highest level by her one owner and her experienced full time captain and crew since new.  She is U.S. flagged, and all duties have been paid.   Also the state of Florida has a great sales tax rule for Florida buyers.  


The Company offers the details of this vessel in good faith but cannot guarantee or warrant the accuracy of this information nor warrant the condition of the vessel.  A buyer should instruct his agents, or his surveyors, to investigate such details as the buyer desires validated.  This vessel is offered subject to prior sale, price change, or withdrawal without notice.

M/Y Diamond Girl has a very successful chartering history and charters are chosen discreetly. She could be quite busy should a new owner choose.  Her unique layout (on-deck Master) & (Master VIP), a yacht of this design is very much in demand.

Being chartered lightly does not in any way take away her impeccable like new "5 Star" interior or exterior appearance.

Replacement Value $7.5 Million plus.
