When you combine aggressive performance, advanced hull innovation, and luxury refinement, you get the ECLIPSE 505 Shadowa standout in the world of express cruisers. As the exclusive ECLIPSE dealer, HMY Yacht Sales is proud to present a vessel that delivers true power with precision. 

Dubbed “art-on-the-water” by Southern Boating Magazine, the 505 Shadow masterfully blends elegance with cutting-edge engineering to create an unmatched ride experience.

Dominating the Water: The Patented SVVT Hull 

The performance backbone of the 505 Shadow lies in its SVVT (Stepped-Vee Ventilated Tunnel) hull, a revolutionary design by renowned naval architect Michael Peters. This patented hull form has powered everything from offshore racers to luxury yachts, and now propels the 505 Shadow to new heights. 

 

Why it Matters: 

The SVVT hull reduces drag by introducing air beneath the hull through a ventilated tunnel system. This technology delivers quicker planing, greater fuel efficiency, and a noticeably smoother ride—especially in challenging sea conditions.

SVVT Hull Advantages: 

  • Increased fuel efficiency 

  • Faster hole shot and acceleration 

  • Greater high-speed stability 

  • Softer, drier ride in rough water 

 

Triple the Power: Mercury 600s 

Under the hood (or rather, on the transom), the ECLIPSE 505 Shadow is equipped with triple Mercury Verado 600hp outboards. This power package is all about balance—speed, quiet operation, and refined throttle control. 

 

Performance Highlights: 

  • Top Speed: 58 MPH 

  • Cruising Speed: 41.6 MPH 

  • Smooth, quiet performance with class-leading responsiveness 

Combined with the SVVT hull, these engines make the 505 Shadow feel confident, composed, and ready for anything—whether you’re slicing through chop or cruising toward the next destination.

Fuel Efficiency That Extends Your Adventure 

Performance is more than speed—it's range, economy, and how far you can go with confidence. Thanks to its optimized hull design and intelligent engineering, the ECLIPSE 505 Shadow is as efficient as it is powerful. 

 

Cruise Efficiency Stats: 

  • Optimal Cruise: 41.6 MPH at 4600 RPM 

  • Fuel Burn: 81 gallons per hour 

This translates to longer cruising ranges and fewer fuel stops, giving owners the freedom to explore more, worry less.

The ECLIPSE 505 Shadow Experience 

Beyond the numbers, the 505 Shadow is about the lifestyle it enables—coastal cruising, island escapes, and weekend adventures wrapped in modern styling and comfort. Its layout is designed with the owner in mind, offering luxury without compromise and performance that inspires confidence. 

As Southern Boating notes, this express cruiser is in a class of its own: “The owner-centric design ensures it stands alone in the express cruiser realm.”
