Description

The 163'11" (49.97m) motor yacht JEMASA carries a fascinating history, having been originally constructed by the Australian Navy as a rugged military survey vessel. Following an extensive conversion, she has been reimagined as a sophisticated explorer yacht that retains its heavy-duty steel hull while offering complete comfort for 12 guests across seven cabins. Her layout includes a full-beam master suite and flexible staterooms that can be configured as either twins or doubles to suit various groups.

Inside, her transformation is defined by a bright, contemporary aesthetic featuring American oak and a neutral palette. The main salon is open and welcoming, providing a relaxed setting that feels far removed from her naval origins. Wellness and entertainment are prioritized throughout the interior, with a dedicated cinema, a games room, and a full spa area equipped with a sauna and massage room for guest use.

Outdoors, JEMASA is designed for those who appreciate the open air. The sundeck features a Jacuzzi and bar, while the bridge deck offers a "glass house" for sheltered dining in any climate. Her naval engineering provides a massive range for long-distance cruising, supported by zero-speed stabilizers that ensure quiet nights at anchor. With a rich selection of water toys and expansive deck spaces, she is a capable and refined platform for unhurried exploration.
