From Jet Engines to Yacht Hulls: Why I Left Aerospace for Maritime By Roman Wroath
After 14 years in aviation propulsion—from RAF flight lines to GE's engineering centres, I made a move that surprised everyone, including myself.
After 14 years in aviation propulsion—from RAF flight lines to GE's engineering centres, I made a move that surprised everyone, including myself. Here's why maritime manufacturing is where I belong now.
The Question Everyone Asks
"You worked on fighter jets. Why boats?"
I've heard this at every industry event, investor meeting, and family gathering for the past two years. The assumption is that I've downgraded—traded precision engineering for... fibreglass and teak?
The reality is the opposite. I left aerospace because maritime manufacturing is where the real transformation opportunity exists. Aviation already had its revolution. Marine is just beginning.
What Aviation Taught Me
I spent seven years in the Royal Air Force as a propulsion engineer, responsible for keeping RB211 engines running. Then another seven at GE Aviation, where I led continuous improvement initiatives across manufacturing operations, setting up new global initiates and running special programmes globally.
Aviation is a mature industry. Processes are standardised. Quality systems are robust. Supply chains are optimised. When you're working on jet engines, you're operating within a framework that's been refined over decades.
The Reality
That's not a criticism, it is a statement of fact. The aerospace industry has solved most of its operational problems. Incremental improvements are measured in fractions of a percent.
What I Found in Maritime
When I first toured a yacht manufacturing facility, I was genuinely shocked.
Here was an industry building €2-3 million products using processes that would have been unacceptable in aviation 30 years ago. Manual layup with minimal quality controls. No standardised work instructions. Tribal knowledge held by craftsmen who'd been doing it their way for decades.
Some people see that and think "backwards." I saw it and thought "opportunity."
The maritime industry is where aerospace was in the 1980s—fragmented, craft-based, ripe for operational transformation. The same Lean principles that revolutionised aircraft manufacturing can deliver 30-40% efficiency gains in boat building. Not theoretical gains. Real ones.
The Numbers That Changed My Mind
Let me share what made the decision clear:
In aerospace:
A 2% efficiency improvement on a production line is a career achievement worth celebrating.
In maritime:
I've seen yards where basic process standardisation delivers 25% cycle time reduction in the first year.
The delta isn't because aerospace engineers are smarter. It's because the low-hanging fruit was picked decades ago. In marine manufacturing, the orchard is untouched.
The Consolidation Thesis
European yacht manufacturing is a €400 million sector dominated by small, family-owned builders. Most have revenues under €5 million. Most are one generation from succession crisis.
This fragmentation creates the opportunity for platform consolidation, acquiring established yards, implementing operational excellence, and building something larger than the sum of its parts.

It's the same playbook that transformed automotive supply chains in the 1990s and aerospace MRO in the 2000s. Maritime is next.
Why Catamarans Specifically
Within yacht manufacturing, the catamaran segment is particularly compelling:
Growing demand:
Charter fleets are expanding. Private buyers want stability and space. The multihull market is outpacing monohulls.
Technical complexity:
Catamarans require more sophisticated engineering than monohulls—structural loads, weight distribution, propulsion integration. This creates barriers to entry that favour capable builders.
Premium positioning:
High-performance catamarans command €1.5-3 million price points with healthy margins. This isn't commodity boat building.
Operational leverage:
Many catamaran builders are operating well below potential because they've never had access to professional operations expertise.
The Skills That Transfer
My aerospace background isn't a liability in maritime, it's the differentiator.
Process engineering:
Standardising work instructions, implementing statistical process control, reducing variation. These fundamentals apply regardless of whether you're building turbine blades or hull sections.
Lean manufacturing:
Value stream mapping, waste elimination, pull systems. The principles are universal; only the application changes.
Quality systems:
Aviation-grade quality thinking applied to marine manufacturing creates products that stand apart in the market.
Supply chain management:
Consolidating suppliers, negotiating volume terms, reducing lead times. The techniques translate directly.
What I've learned is that operational excellence is a discipline, not an industry. The specific knowledge of composite layup or marine systems can be acquired. The mindset of continuous improvement, data-driven decision making, and systematic problem solving, that's harder to develop.
Where This Is Going
The goal isn't to change what these yards build, it's to change how they build it. Faster, more consistently, more profitably.
Five years from now, I expect we'll have created a meaningful player in the European yacht market. One that combines craft heritage with operational excellence. One that proves maritime manufacturing can achieve aerospace-level efficiency without losing its soul.
The Bottom Line
I didn't leave aerospace because I was bored or because the opportunities had dried up. I left because I found something more compelling, an industry with genuine transformation potential, where my skills could make an outsized impact.
From jet engines to yacht hulls? It makes more sense than you'd think.
