MM751: Malcolm McKeon's Latest 75m Milestone

This brand new catamaran concept is shrouded by dark hull sides and a glass superstructure, MM751 encases its occupants in a stylish arrangement that is completely new to the world of superyacht design.

With low-profile exterior lines that run uninterrupted from bow to stern, this sailing yacht has a particularly linear look, accentuated further by a sloop rig that stands 88 metres above the deck.

When it comes to onboard lifestyle and amenities, being able to equip the yacht with large tenders was a key design consideration. A 12m guest tender is stowed to port and a 9m crew tender is found to starboard.

MM751 serves as something of a platform to facilitate water sports, scuba diving and extended coastal excursions. With the tenders deployed, fold-down balconies in the hull sides create a gym and additional deck space that can be shaded if desired.

At MM751’s stern, the full-beam swim platform can be raised and lowered, and provides options for a beach club setup.

Within, MM751 features an interior designed by m2Atelier. It adopts an open-plan layout for the main living area and this runs athwartships, progressing from a formal dining area to port, to a central lounge, and then a cinema lounge to starboard.

The space is flanked by floor-to-ceiling windows in the hulls, which extend overhead to become skylights that bring an influx of natural light from above – reinforcing the all-important visual connection with the sea and surroundings.

The main galley has also been given a promotion to the main deck and resides to port adjacent to the dining room. In this way, food and drink is placed centre stage and the galley is best located to serve both the aft deck and dining room. Heightening the focus on fine dining further still, MM751 features a 600-bottle wine cellar beneath a statement glass panel in the main deck.

MM751 has accommodation for 12 guests across six suites. If desired, the forward section of main deck, where the master stateroom and VIP suite reside, can be closed off to become a full-beam owner’s apartment with private lounge. As access to the foredeck is via the forward lobby, this also privatises the forward deck space.

Accommodation for 12 crew plus an additional cabin for supernumeraries is located on the lower deck of the port hull. 

The advantages of a catamaran hull configuration are many. With MM751, these are characterised by the minimal heel angle, greater stability, and expansive, uncluttered deck spaces.

Under motor, MM751 has a top speed of 17.5knots and a range of 2,000nm. At a more economical cruising speed of 12 knots, the range extends to more than 4,200nm.

The diesel-electric system allows for silent operation at lower speeds and electrical regeneration while sailing with power fed back to the battery bank, in addition to the energy provided by solar panels in the glass skylight.

Under the prowess of her sails, MM751 will outperform true wind speeds, easily attaining 1.5 x wind speed in light airs and over 25 knots in stronger breeze – all with a heel angle of less than five degrees.

The sails run from captive winches with push-button control. The mainsail is a square top with boom furling, and the foresails are on hydraulic under-deck furlers with the downwind code sail stored on a drum in the forepeak.

MM751 is equipped with telescopic daggerboards, optimising upwind sailing performance whilst providing the option for reduced draft in shallower waters and increased efficiency while motoring.
