A Quiet Expansion of Capability

Sustain represents a shift in how a support vessel can contribute beyond its immediate program, positioning itself as both operational infrastructure and a platform for meaningful engagement. Designed as a 68-meter catamaran with sustainability at its core, the vessel enables owners to extend their impact without altering their experience. It reframes the role of a shadow vessel from purely logistical support to an active participant in environmental stewardship, aligning capability with purpose in a way that feels seamless and intentional.

At the heart of Sustain is a highly flexible, multi-functional design that supports research, conservation, and exploration alongside traditional yachting operations. Dedicated facilities including wet and dry laboratories, medical spaces, dive centers, and submersible support allow the vessel to host scientists, researchers, and expedition teams without compromising its primary role. This integration of capability creates a platform where discovery and leisure coexist, enabling owners to engage with the environments they visit in a more informed and impactful way.

What distinguishes Sustain is its concept of effortless engagement. The vessel is designed so that participation in research or conservation initiatives does not require operational complexity or sacrifice from the owner. Its intelligent layout and inherent capacity allow it to support additional personnel, gather data passively, and facilitate collaboration in the background of a typical cruising program. The result is a vessel that not only sustains its mothership, but also contributes to sustaining the environments it operates within, setting a new standard for responsible yachting.
