His journey took him from ferry operations and cargo logistics to an extensive 15-year tenure aboard Superyachts, where he mastered the intricacies of yacht maintenance and operations. Rising to Chief Officer on vessels over 3000GT and earning his 200-tonne captain’s license, Luke understands yachts inside and out—from the bridge to the engine room.

Beyond yachts, he’s a proud dad to two young boys with his wife, Molly, balancing family life with his passion for delivering world-class yacht care.

More than just managing maintenance, Luke’s focus is on creating seamless, stress-free ownership experiences for his clients. Whether it's executing a tailored maintenance plan, troubleshooting an issue before it becomes a problem, or helping owners better understand and operate their vessels, Luke is committed to ensuring every yacht under his watch is ready to perform when it matters most
