This pedigree superyacht for sale was built in 1999 by Trident and has been maintained to very high standards. An interior refit was completed in 2020 enhancing the yacht’s elegance while remaining inviting and comfortable. Recent work has included rebuilding main engines to zero time, an interior refresh and all new teak on the bridge deck, swim platform and steps. 

M4 131' 1999/2020 Trident Shipworks Tri-Deck Motor Yacht boasts an elegant, refined and inviting interior by VM Design that is filled with light thanks to oversized windows, a wide 28’ beam and tall 7’1” ceilings. Exceptional millwork is complemented by a light color scheme and beautiful furnishings. Great thought was given in designing the layout to make the yacht crew and service easy and friendly. Guests can take their pick from numerous social spaces inside and out, with plenty of options on every deck. Key interior hubs are the main salon and sky lounge, which are connected together by a stunning wooden staircase that is akin to a piece of art. 

The main salon features plenty of sofa seating and a marble coffee table, with a modern entertainment system. A separate dining space has seating for all guests. Located on the upper deck, the sky lounge is a comfortable retreat with seating options, a coffee table, games table and a full bar for sharing beverages prepared by the skilled crew. The yacht has VSAT high speed internet installed, for seamless connectivity.

Up to nine guests can be hosted on board overnight, and up to 12 guests when cruising. The accommodation layout is especially appealing, with four ensuite cabins that include two masters, one queen and a twin. The huge king on-deck master is located forward on the main deck, while the second full beam master is on the lower deck. Each cabin has a huge amount of space and elegant proportions that guests will delight in. Each cabin is beautifully outfitted, with the same high-quality woodwork that is seen throughout the interior, plus marble en suites.

Outdoor spaces are plentiful. The relaxed sun deck is packed with equipment for enjoying the sunshine including sun loungers, shaded seating and an al fresco dining set up. The bridge deck aft also has a dining table, with sun loungers and more seating. Down on the main deck there is another dining space with comfortable seating. Her crew of seven provide professional and welcoming service.

Sweeping steps lead from the main deck to M4’s large swim platform, which is ideal for water sports and swimming. The yacht has plenty of storage for her impressive line-up of toys and tenders. 

With transatlantic capabilities, M4 131' 1999/2020 Trident Shipworks Tri-Deck Motor Yacht cruises at 12 knots, and a shallow draft makes her well-suited to the beautiful Bahamas. Her engines have been freshly overhauled, with zero hours, and she has a huge ship-sized engine room that is immaculately kept.  Dependable Caterpillar engines and generators are easy to service and economical to operate using only 48 gallons per hour at cruising speed. American fiberglass construction and equipment reduces maintenance and costs.

Offering impressive amounts of space, a stylish design and endless amenities, M4 131' 1999/2020 Trident Shipworks Tri-Deck Motor Yacht  is a superyacht for sale that must be seen to be fully appreciated.

General Walk Through of M4 131' 1999/2020 Trident Shipworks Tri-Deck Motor Yacht

On the SUNDECK above the wheel house is a large lounging settee which occupies the rear area directly under the radar arch with lounge chairs, and teak cocktail tables.

Forward is a smart observation deck with comfortable seating and lounges. Centerline Jacuzzi.

The UPPER DECK has a center walkway to the FOREDECK where a tender is stowed along with two personal watercraft, kayaks, etc., and cranes are located on the foredeck. Storing the tenders on the bow allows the tenders to be stored without disturbing guests.

The WHEELHOUSE is finished in teak and with a teak floor. The visibility is excellent. There are two large helm chairs and a large 4 person curved settee aft. The wheelhouse features an array of monitors that can be switched to monitor various systems. The monitoring system was updated in October 2015 to a new state of the art Maretron system. 

The CAPTAIN’S CABIN with queen bed and bathroom leads off the SHIP’S OFFICE on the port side. A privacy door leads back from the bridge to the sky lounge. A Dayhead is located right side.

Behind the bridge is the SKY LOUNGE, which includes a full bar and round card/dining table on the port side with large seating areas on the starboard side. The sky lounge opens to a sky lounge deck set up for alfresco dining for eight with a teak dining table and full awnings. Coffee table and teak and rattan lounge chairs and couch.   A beautiful curved stairwell located forward of the sky lounge leads down to the main deck and guest accommodations.

Forward of the main deck stairwell is the formal DINING ROOM. A six foot table seating 8 is centered between elegantly curved half walls. The result is a feeling of intimacy and enclosure while maintaining the openness of the main deck. The table was custom made in England and the room’s Matelasse chairs were hand carved in Italy.  The dining room is equipped with extensive concealed storage areas in the dining room for china and glasses. To left and right are double doors to the side deck for gracious entry to the yacht.  

Aft on the main deck is the MAIN SALON with exceptional visibility with very large windows and 7'1" (2.16m) high ceilings and traditional raised paneling. The yacht had an interior refit in 2020 and the décor speaks of style and timeless elegance. The color palette is soothing with an emphasis on textures and a pop of color. The TV and AV systems are concealed.

Double glass doors lead to the AFT DECK, with a u-shaped settee that can seat 12 for alfresco dining. The stairwell to the bridge deck is on the starboard side. This area has drop down rear enclosures and side sliding glass doors so the aft deck can be comfortable in all conditions. Stairways from the aft deck lead down to the swim platform tender and boarding area.

Forward of the dining room on the left side is a hallway that leads to the main deck dayhead and the owner’s suite. On the right side there is a privacy door with a complete butler’s pantry equipped with excellent storage, small kitchen appliances and espresso machines.

LOWER DECK AND FORWARD: Crew accommodations for 6 in three CREW CABINS all with private bathrooms and two single bunk beds, with an additional stateroom with double bed on the bridge deck for the captain.
