More details of Heesen's 60m superyacht Ultra G revealed by designer

Further details of Heesen's 60-metre full-custom superyacht Ultra G have been revealed by her interior designer.

The yacht was delivered to a new owner in March following her sale, both of which were "coordinated with the Dutch authorities", according to Heesen. She has now undertaken her maiden voyage to Guernsey.

Ultra G is one of Heesen's most powerful projects to date with a propulsion package totalling 22,000 horsepower, including four water jets, resulting in a top speed of 37 knots in light load conditions.

Described by the yard as a “sport fisherman in yacht disguise”, the custom design draws inspiration from two previous sportfishing models built by Heesen in the nineties and features a fighting chair and storage for 40 rods.

A deeper dive into Sparta's interiors, with a range of imagery, is now available exclusively to BOAT International.

Exterior design is the work of Frank Laupman's Omega Architects, and the studio was specifically chosen to create the yacht's unique lines, while the interior is the work of British studio Harrison Eidsgaard.

The 918GT interior includes accommodation for ten guests in four cabins on the lower deck. Meanwhile, the bridge deck has been reserved for the owner’s accommodation, which comprises a large aft-facing cabin that opens onto a private terrace equipped with a Jacuzzi and relaxation area. At the request of the owner, the yacht has dog-friendly features throughout – including a dedicated "dog-relief" area on the owner's private terrace.

Entertaining is a core part of Ultra G's design, with a custom wine fridge in the main saloon and a large media room with the latest audio-visual equipment. There is a games table on the main deck forward and a sundeck with an infinity pool facing aft.  

Replacing a traditional beach club is a fishing platform and a "Fisherman's Lounge" which complements the technical setup – equipped with comfortable sofas and live feeds from underwater cameras. There is also a wellness area featuring a spa with a beauty salon, sauna, steam room and snow room.

The waterjet propulsion drives the yacht's draft to less than three metres and helps to reduce vibrations. Meanwhile, the lightweight aluminium Fast Displacement Hull Form, complete with course fins, gyro stabilisers and interceptor trim plates, promises a smoother onboard experience. The engines are also compliant with IMO Tier III regulations.

Ultra G is expected to be accompanied by a custom tender built by Vanquish to a design by Guido de Groot that "mirrors the mothership down to the last brushstroke”. When she was originally commissioned, she was also fitted with dog-friendly features including a "relief area".

The statement from Heesen continued: "Everyone at Heesen is delighted to see another motor yacht from their full custom range sailing away and wishes her owners and crew fair winds and following seas".

This follows news earlier this month that the yard's 56.7-metre Project Akira has entered outfitting ahead of her launch.
