First impressions

Streamlined and distinct exterior lines penned by Omega Architects have resulted in a high performing, fast and efficient superyacht. With a maximum speed of 25 knots, Jems allows you to take in more of your chosen destination and is one of the few yachts of this length to reach such exhilarating speeds.

Step aboard

Jems features a unique and modern interior designed by Eric Benqué. Spacious with clean lines, one of the key features of Jems is flexibility; almost every piece of furniture has been specifically designed to be convertible to provide a maximum range of environments to suit varied guest requirements.
