Design & Construction

Designed around a full displacement aluminium hull and superstructure she features a 16.6m beam and a 2.8m draft. The yacht has an internal volume of 499 GT (Gross Tonnes).

Launched in July 2011 this yacht undertook sea trials over the following months.

Exterior Design

The 44.2m (145ft) Hemisphere has a very different presence from a conventional superyacht, and the photo makes that obvious at once. Built as an auxiliary sailing catamaran by Pendennis Shipyard to a VPLP design, she spreads her 16.6m (54.5ft) beam across two slender aluminium hulls, so the whole yacht sits low, wide, and remarkably stable in profile.

Her guest spaces are arranged around that width. The main aft deck stretches cleanly across the bridge between the hulls, and from there broad staircases descend to twin transom platforms at the stern, giving direct water access on both hulls. The image also shows how open the deck layout is, with very little visual clutter, which was a deliberate part of the design. Winches, bollards, and working gear were kept discreet so the outdoor areas could feel open and social rather than technical.

Above, the flybridge forms the yacht’s main exterior hub. It is reached from the aft deck by a single portside stair and is centred around a spa pool between the twin helm stations. Aft of that sits a dining table for 12 with a world map etched into the glass top, while surrounding lounge seating and open deck space make full use of the catamaran’s beam. The photo also shows how this upper deck reads almost like a rooftop terrace, with generous lounging space and broad sightlines in every direction.

Forward, the superstructure is kept low and broad, and the dark glazing band wraps around the saloon to emphasise width rather than height. Teak decking is used selectively rather than everywhere, so weight stays down and maintenance stays sensible. According to the build approach, teak is concentrated in the guest areas where people spend the most time, including the main aft deck, the flybridge, and the veranda forward of the VIP cabins.

The twin-hull form also creates unusual storage and launch solutions. The main tender, an 8.2m (26.9ft) Scorpion RIB, is stowed between the hulls below the aft deck and launched through bomb-bay-style doors, while a 4.5m (14.8ft) Castoldi RIB sits aft in the starboard hull and launches through an inboard shell door by C-Quip beam crane. That arrangement keeps the decks clear while also making the most of the catamaran platform.

Above everything rises a 53m (173.9ft) spreaderless mast by Lorima, supported on a single giant ball bearing. It gives Hemisphere the scale of a serious sailing yacht, but also suits the clean, architectural look of the whole design.

Interior Design

The interior of Hemisphere was designed by Michael Leach Design, and it uses the catamaran platform to create spaces that feel wide, open, and connected rather than enclosed.

The main saloon sits at the centre of the yacht and spans over 100 square metres. It is arranged across split levels, so different areas are defined without breaking the flow of the space. Motion-activated curved sliding doors connect directly to the aft deck, and the seating area to port is raised slightly to improve sightlines through the wraparound glazing.

A bar or breakfast counter sits lower within the space, and the floor behind it drops further to allow discreet crew service without interrupting views. This layout keeps the room visually open from forward to aft, which suits the yacht’s emphasis on shared social areas.

Off the main saloon, a separate television room or snug is built into the port hull. It is reached by an atrium-style staircase, and it provides a quieter interior space while still remaining connected to the main living area above.

Materials are layered throughout the interior rather than applied in a uniform way. Walnut soles run underfoot, while brushed oak and wengé panels add contrast across bulkheads. Surfaces are chosen for texture as much as finish, and the mix includes multiple leathers, stone types, and metalwork. Onyx is used in several areas, and in some cases it is backlit to highlight the natural pattern within the stone.

Accommodation

Hemisphere accommodates up to 12 guests in five cabins, with a very unusual arrangement for a yacht of this size. Instead of a single conventional owner’s suite, the forward main deck is given over to two VIP cabins. These sit side by side in the forward section of the bridgedeck structure, and they are separated by a removable partition. When that partition and its associated cupboards are removed and stowed, the two cabins combine into a master suite stretching the full 16m (52.5ft) width of the yacht, complete with dual en suites.

A further guest cabin sits in the port hull off the central lower lobby, while aft in the same hull are two more guest cabins. One of those cabins includes two fixed berths and two Pullman berths, so it was intended to suit grandchildren or younger guests especially well.

Crew accommodation occupies most of the starboard hull, which keeps the separation between guest and service areas clear. The crew area is accessed both from its own companionway and through a sliding door between the saloon and the main galley. Forward are the crew mess and laundry, while aft are three crew cabins. Total crew accommodation is for 10, including the captain’s cabin.
