One of the most overlooked indicators of yacht quality isn’t visible from the helm, the salon, or the flybridge—it’s below deck, in the engine room. On both the GrandOcean W-72 Power Catamaran and W-60 Power Catamaran, the engineering and layout tell a clear story: these yachts were designed by people who understand real-world maintenance, reliability, and serviceability.
Unlike many engine rooms that feel cramped or cluttered, the W-72 and W-60 feature exceptionally smart design choices that make daily checks, long-term servicing, and even major equipment installation noticeably easier. For owners, captains, and technicians alike, this translates to lower labor costs, better upkeep, and longer system life.
Below, we take a closer look—guided by Harry—inside the W-60’s starboard engine room and the standout design features shared by both models.
A Better Approach to Engine Room Access
Most yachts offer standard hatch access to the engine space, but GrandOcean takes it a step further. There are two levels of entry:
Primary Access Hatch
A quick-open hatch allows the owner or crew to step directly into the engine room for routine checks—oil, belts, filters, strainers—without removing major panels or floorboards.
Full Deck Lift Section
When more extensive work is needed, the entire deck section lifts up via heavy-duty lugs, allowing complete top-down access. This is invaluable for major servicing, equipment replacement, or even engine removal.
It’s simple, smart, and built for real-world use. As Harry notes:
“If it’s easy to reach, you’re more likely to maintain it.”
GrandOcean clearly agrees.
W-60 Starboard Engine Room: Power, Space & Practical Design
Stepping into the W-60 engine room, the first thing you notice is space—actual room to move around the machinery. At 5’11”, Harry can comfortably walk and work around both sides of the Cummins 550hp engine.
Cummins 550hp Engine
Reliable, efficient, and well-supported globally, the Cummins powerplant is a strong match for a luxury power catamaran focused on comfort and long-range performance.
Systems That Support Comfort & Reliability
Hot Water Tank
Mounted prominently for easy access, the tank supplies hot water for showers, galley use, and onboard systems.
Engine Exhaust System
Cleanly routed and clearly labeled, the exhaust line runs to the aft exit point, with ample space for inspection and service.
Battery Switch Box
Oversized switches and clear labeling provide straightforward electrical control—no reaching into tight corners or hidden compartments.
Dual Water Pumps
The yacht includes two pumps for improved redundancy and reliability, helping ensure continuous freshwater pressure onboard.
Victron Skylla-IP65 24V 70A Charger
A robust charger mounted neatly for visibility and airflow, offering dependable charging with Victron’s proven marine-grade architecture.
Advanced Protection & Safety Systems
Active Biofouling System
A standout feature: an electronic anti-fouling shield designed to reduce growth around the bows. This not only improves efficiency over time but reduces the need for frequent diver cleanings.
Emergency Fire Stop
A clearly marked emergency stop button ties into the vessel’s fire suppression system.
Fire Suppression Unit
Should a fire occur, the system automatically activates—another sign of the builder’s focus on safety and redundancy.
Deck Drainage Plumbing
All deck drainage routes through designated channels visible within the engine space, making it easy to inspect and service.
Dedicated Engine Room Blower
Ensures constant airflow, temperature control, and fume removal—critical for engine longevity and onboard safety.
Shore Power Connection
A neatly routed shore power cable sits ready for easy use, further emphasizing the tidy, considered design.
Superior Layout = Easier Ownership
From double jubilee clips to clearly routed wiring and plumbing, everything inside the engine rooms of the W-72 and W-60 feels deliberate. Nothing is buried. Nothing is guessed. Everything is reachable.
Why does this matter? Better access means:
-
Faster repairs
-
Lower maintenance costs
-
Easier equipment upgrades
-
Longer system lifespan
-
Less hassle for owners and crew
This is the kind of design detail that often goes unnoticed—until it saves time or money.
The GrandOcean Difference
While the W-72 and W-60 are known for their expansive living spaces, luxurious finishes, and long-range comfort, it’s the engineering beneath the deck that truly elevates these models. GrandOcean has built yachts that don’t just look good—they’re built for owners who truly use their boats.
Engine rooms that feel open, organized, and intuitive are rare in this size class. Learn more about how the GrandOcean PowerCat Luxury Yachts have set a new bar.
