What features does Heesen’s new superyacht add?

Heesen’s latest steel superyacht goes big on onboard tech

Heesen has unveiled plans for what it describes as its largest steel superyacht yet: a 237-foot vessel that also introduces a pair of high-end additions meant to elevate comfort and capability. The ship design includes a helipad—a clear sign the yacht is built for owners who want direct, private access—and a hyperbaric chamber.

That hyperbaric feature is especially notable because it signals the vessel isn’t only about luxury finishes and leisure space; it also targets wellness and recovery. Hyperbaric chambers are commonly associated with medical and therapeutic use in broader healthcare contexts, so placing one onboard implies an emphasis on readiness, convenience, and long-duration trips without relying on shore-based facilities.

Heesen also framed the launch around record-setting scale, overtaking its prior yard record for size. For the superyacht market, that kind of escalation matters because new builds often compete on headline specs: length, materials, and standout capabilities that differentiate one owner’s experience from another.

The headline takeaway

• 237 feet: Heesen’s largest steel yacht to date.
• Helipad onboard: Direct arrival and departure options.
• Hyperbaric chamber: Wellness/recovery capability built into the ship.

Overall, the design pitch is consistent: the newest big steel yacht is aiming to be self-contained—able to host owners and guests like a private resort, while also carrying specialized infrastructure typically found off the vessel.
