Laurent Giles reveals 110m superyacht concept HEMY

12 June 2017By Chris Jefferies

British naval architecture studio Laurent Giles has released its latest superyacht concept, the 110 metre High Efficiency Motor Yacht (HEMY).

This design aims to maximise the length of a yacht that can be built under the LY3 classification, thus removing the need for lifeboats or restrictions on outfitting materials. As a result, HEMY would be one of the world’s largest yachts to have a total interior volume of less than 3,000GT.

HEMY would accommodate 14 guests and 32 crewmembers

The studio adds that the hull has been designed to be ultra-efficient, requiring just over 5,000hp to reach its top speed of 20 knots. When trimmed back to a cruising speed of 17.5 knots, HEMY would be capable of covering 6,500 nautical miles without needing to refuel. Other key statistics include a beam of 12.5 metres and a maximum draught of 3.8 metres.

Accommodation is for up to 14 guests split between an upper-deck owner’s cabin and four main deck double cabins. Meanwhile, the crew quarters would allow for a staff of up to 32 people.

Standout features on HEMY include a pair of superyacht beach clubs — one amidships and another at the stern that could be fitted out as a dive centre. Moving to the main deck and the open-plan saloon features a lounge area and seating for all 14 guests around a single dining table.

The foredeck helicopter pad conceals a main deck helicopter hangar beneath, while the nine-person cinema room can be accessed directly from the guest area. Tender storage is plentiful, with room for an 11 metre limousine, three Jet Skis and two more tenders in the side-loading garage. But the most eye-catching feature is the transom, with curved teak decking complimenting the vast aft-deck infinity pool.

HEMY would cruise at 17.5 knots

David Lewis, managing director of Laurent Giles, added: "The concept was to start with a typical 70-75 metre yacht and lengthen the hull to offer increased interior volume, while remaining within a 3,000GT limit. Not only does HEMY offer increased accommodation volume, but with its more efficient length/beam ratio and lighter displacement/length it offers significant improvements in performance and seakeeping."

Full details of the twin-screw propulsion system are yet to be disclosed, but a pair of amidships stabilisers would ensure a smooth cruising experience.
