Design and construction

At the core of the ECLIPSE 505 Shadow lies a proprietary twin-stepped, hard-chine planing hull with a centerline tunnel, engineered by Michael Peters Yacht Design to the esteemed Stepped Vee Ventilated Tunnel blueprint, protected under Patents # US 8,291,850 B1 and # US 8,800,464 B1. Owners may specify engines in white or black, while the composite hulls, decks, and coach roof feature a gel-coated outer layer with all final finishes painted in Alexseal. Below the waterline, a Vinylester barrier coat safeguards against osmosis, with polyester resin joined to a high-performance E‑Glass laminate and PVC foam core for a stiff, light, and enduring structure.

Everywhere you look, the build is optimized for strength-to-weight: interior joinery and floorboards employ cored panels for rigidity without bulk; exterior surfaces are gel-coated and/or sprayed and painted to a high-gloss standard; while interior and below-deck areas are finished in Marine Flo Coat. The one-piece hull lamination is paired with high-density foam-cored construction using vacuum-bag technology, and carbon fiber–reinforced structural components further consolidate strength and precision.

Dimensions

With an LOA including motors of 50'10" and a molded LOA of 46'11", the ECLIPSE 505 Shadow balances presence and agility. Its waterline length is 40'8", with a maximum beam of 15'1" and a chine beam of 11'2". Draft of the hull, excluding motors, is 2'11", while the air draft, also excluding motors, is 12'10". Lightship displacement is 26,000 lbs. The yacht provides two staterooms and two heads, and is certified to ISO Category B while meeting USCG requirements and ABYC recommendations.

Shadow performance package upgrade

The Shadow Performance Upgrade transforms the 505 into a limited-production athlete with presence: triple Mercury 600 V12 outboards are precisely color-coordinated to your chosen palette or rendered in traditional white or black, backed by Mercury Marine Platinum Extended Warranties for all three power plants and associated hardware. Design Unlimited Shadow reimagines the interior with a custom-level execution, unveiling an entirely unique seating design and appointments inside and out, complemented by color-matched leather and trim accents throughout. Six limited-edition hull colors—exclusive to a single model year—are tailored to harmonize with your interior, while the Shadow-exclusive mast can be finished to match the hull or in silver. A no-cost badging delete option on both boat and engines completes the stealth aesthetic.

The Shadow Technology Upgrade integrates a full Garmin electronics suite seamlessly into the luxurious Silver Arrows helm, including a 4-foot open array radar, AIS, sounder, VHF, the Garmin Surround View Camera System, and a Starlink satellite data system—bringing a command-center clarity to navigation, communication, and awareness.

Mechanical

Propulsion is delivered by triple Mercury Verado 600 hp 7.6L V12 outboard motors, each with a steerable dual-prop gearcase and a two-speed transmission for precise handling and relentless thrust. The genset’s cooling water is discharged below the waterline, with the gas outlet at the starboard transom, while air conditioning uses individual Dometic split systems mounted in non‑corrosive trays; condensation trays lead to grey‑water sumps, and seawater drains to the proprietary Infinity drain within the boot stripe, port side aft. ElectroSea comes standard for reliable seawater system protection. Fuel lines are 316 stainless steel or USCG‑approved marine hose as appropriate, and the underwater generator exhaust employs Centek FRP components and tubing with approved silicone marine hose.

Domestic systems include a Kuuma 11‑gallon (42 L) water heater operating on 120 VAC and/or generator cooling circuit, a pressurized freshwater pump by Headhunter Mach5, and pumps and rotating machinery mounted on rubber isolators with flexible connections for low vibration. A thermostatic mixing valve prevents scalding. A transom‑mounted high‑speed seawater pickup feeds a central sea‑chest—Hooker or equivalent—located in the lazarette, supplying seawater consumers throughout the vessel.

Electrical

The yacht is wired to 120 VAC 60 Hz US standard voltage with a 50 A shore connection aft to starboard, handled by a Glendinning CM‑7 cablemaster and tub. Anchoring is effortless with a 24 VDC Lewmar VX2+ vertical windlass offering powered up/down and free‑fall, with local control and remote operation at the helm. Cabling and switching are streamlined via CZone or similar digital switching, with controls on‑unit and at the helm or main electrical panel. A Northern Lights 13.5 kW 60 Hz generator pairs with a 1 kW inverter for small loads, and all starts are cleanly segregated: outboards and generator on 12 VDC; house and other loads on 12 or 24 VDC as specified. Each outboard motor has a Group 31 AGM start battery, the generator has a Group 24 AGM start battery, and there are two Group 31 AGM house banks. Multi‑bank chargers maintain all start and house batteries on shore or generator power, while isolation and switching allow emergency starting of all outboards and generator, feeding 12 V from start to house loads, and charging all batteries from alternators underway.

Switchboards, sub‑boards, breakers, and equipment are by BlueSeas and CZone. Interior and exterior lighting is LED, with local switching and centralized mood‑setting capability; the mast carries a forward‑facing searchlight with remote control at the helm. Machinery spaces, the forepeak, and storage areas are LED‑lit, as are the navigation lights. The DC electric steering system is integrated with the outboards. The sea‑chest is fitted with 12 VDC booster pumps to ensure supply, with a standard thru‑hull feeding the sea‑chest in the tunnel section as an over‑pressure relief/astern pickup. Seawater outlets are consolidated and led aft to the Infinity drain system, and an optional seawater wash system can feed from the sea‑chest or a dedicated thru‑hull with quick‑connect outlets at the anchor locker and in the cockpit.

Salon

Climate comfort is assured by two 16,000 BTU air‑conditioning units, while a vast Vetus Marex flush glass sunroof—approximately 8'6" by 6'11"—floods the main deckhouse with light. Plush seating invites conversation, and a custom sliding aft door delivers a seamless, flush‑deck transition between the aft deck and salon. A 50" Samsung Smart LED television rises on a powered lift, paired with a Samsung audio system for immersive entertainment, and thoughtful storage keeps bottles and glassware secure. Convenient access leads to the lower hull cabin areas, creating an effortless flow between social, dining, and private spaces.

Helm

Command comes naturally with Mercury digital controls, joystick, Skyhook, and a VesselView display integrated into a comprehensive, touchscreen‑driven navigation and communication suite. Garmin GPS with electronic charting, radar and satellite overlays, and multiple GPS sources pairs with an autopilot featuring route‑following and a dedicated electronic compass, a fixed‑mount VHF with its own antenna, an AIS transceiver with a dedicated antenna, a 4' open array radar, and a digital depth sounder. Optional Seakeeper Sk6 stabilization resides below the aft galley, while Humphree systems bring interceptors with two 450S trim tabs and an optional auto‑stabilization feature on the trim control.

A 12 V electric bow thruster, Side‑Power SEP120/215T or equivalent, is sized for seamless joystick integration. Main engines, generator, and electrical systems are fully monitored with alarms at the helm, and tank fluid levels are displayed via electronic sensors. For acoustic refinement, the overhead in the machinery/storage space below the aft cockpit is lined with Soundown. Underfoot, the bow cockpit features a 12 mm first‑grade teak sole.

Galley

The gourmet galley centers on Thermador under‑counter refrigerator/freezer drawers—two in total—with a built‑in icemaker within the Thermador freezer, all beneath elegant quartz countertops. FRP modules form robust cabinetry and counters around a Thermador four‑burner induction cooktop, Thermador integrated power ventilation, and a Thermador convection and microwave oven. A sink with garbage disposal, a concealed under‑counter trash drawer, custom accent wood carpentry, pot and spice drawers, and fitted cutlery storage to prevent rattling complete the culinary experience, while an extended built‑in bar and wine cooler add capacity and flair with additional storage.

Master stateroom (forward)

The forward master is a sanctuary with a 12,000 BTU air‑conditioning unit, FRP modules combined with custom carpentry, and a custom queen‑size bed. Reading lights and ambient cabin lighting complement a refined headliner with recessed LEDs, while color‑coordinating blinds temper light over the hull‑side windows. A Lewmar Size 70 Flush 3G hatch crowns the forecabin roof, and a full‑height wardrobe with cedar lining keeps attire fresh and impeccably organized.

Guest stateroom

Guests enjoy a 10,000 BTU air‑conditioning unit and berths that smoothly convert from twins to a double via slides with DC electric actuation. FRP modules and custom carpentry frame the space, with dedicated reading and cabin lights, nightstands with switches and outlets, and a headliner with recessed LEDs. Blinds soften light over the hull‑side windows, while a full‑height wardrobe with cedar panels offers generous stowage. Overhead, two Lewmar Size 60 Flush 3G hatches—port and starboard in the forecabin roof—bring in natural light and breeze.

Master & guest head

Both the master and guest heads are appointed with separate walk‑in shower, head, and basin areas, and robust shower doors fitted with three hinges each to withstand high‑speed shock loads—luxury engineered to perform under way.

Tankage

Fuel capacity is generous, with gasoline totaling 568 gallons (2150 L) across two custom welded and baffled aluminum tank assemblies—one port and one starboard—each protected with anti‑corrosion coatings and fitted with bonding and grounding connections. A dedicated diesel supply of 30 gallons (115 L) resides in a single custom welded and baffled aluminum tank with anti‑corrosion protection, bonding and grounding, and a clean‑out port. Fresh water totals 150 gallons carried in two 75‑gallon (285 L) midships tanks in poly or FRP, while black water capacity is 65 gallons (245 L) forward in a single poly or FRP tank. Grey water is managed without a dedicated tank via sumps with DC pumps and float switches.

Fuel

For gasoline, twin stainless steel deck fills expedite bunkering, feeding a purpose‑designed fuel manifold and tanks whose fill and vent lines are partitioned and sealed off from interior, mechanical, and storage spaces. Two flush‑style stainless steel vent fittings on the topsides ensure proper breathing, while water‑separating fuel filters safeguard engine health. The gasoline supply is contained within two custom welded and baffled aluminum tank assemblies—one port and one starboard—with anti‑corrosion coatings and comprehensive bonding and grounding.

For diesel, a flush‑style stainless steel vent fitting on the topsides, a stainless steel deck fill, and a water‑separating fuel filter ensure clean delivery to the genset. The diesel is held in a single custom welded and baffled aluminum tank with anti‑corrosion coatings, bonding and grounding connections, and a clean‑out port for serviceability.

Water systems

A self‑contained shower sump/pump unit serves both showers, and dockside blackwater pump‑out is handled via a stainless steel deck discharge fitting. Independent blackwater discharge pumps for the port and for the starboard blackwater tanks each have dedicated underwater outlets, enabling flexible operation. Piping systems are designed with fittings for thorough flushing, draining, and winterization. Fresh‑water piping uses PEX tubing or approved marine hose, while waste and black‑water piping employs PVC or approved marine sanitation hose. Sanitation is delivered by two Headhunter Bravo or equivalent water‑jet macerating toilets, with two Wye selector valves featuring locking provisions, and two thru‑hulls with seacocks for overboard toilet discharge.

Deck / exterior

The aft deckhouse overhang discreetly incorporates Seasmart hardware for a canvas sunshade supported by removable poles that seat into sockets at the transom. All molded FRP parts carry a gelcoat finish, and cap rails in molded FRP ring the main deck, optionally finished in faux teak paint with an LPU UV inhibitor. Exterior cushions are upholstered in Sunbrella fabric with anti‑microbial, self‑draining foam inserts and hidden tie‑downs, and both cushions and cabinets are protected by removable soft covers made from waterproof Stamoid. Throughout the aft cockpit and swim platform—extending onto the fold‑down side platform—the decking is 12 mm first‑grade teak, while main deck and housetop walking surfaces are finished in non‑skid. Drains feature polished, removable stainless steel grates, and a custom hinged or vertically sliding aft salon window with polished stainless trim erases the boundary between indoors and out. The hull and boot stripe are expertly painted for enduring brilliance.

Boarding and safety are elegantly solved with a removable stainless steel swim ladder that locks into sockets in the fold‑down side platform, plus a Garelick EEz‑in (or equivalent) retractable emergency reboarding ladder at the transom. Mooring hardware includes eight 250 mm Gemlux stainless steel pop‑up cleats—two at the bow, two at the stern, and two on each side deck—paired with seven custom stainless steel fairleads that fit flush and integrate with the toe rail and transom cap, and eight flush Seasmart stainless steel fender attachment points, four per side. A stainless steel bow eye and transom tie‑down eyes support trailering. Exterior railings and fittings are 316L stainless steel, with all welds ground, smoothed, and polished; bases use hidden fasteners where possible, with countersunk flush screws elsewhere. An optional bow rail features a minimum 30 mm top rail and 25 mm stanchions, and rail heights comply with ABYC and ISO guidelines. Large‑section rub rails trimmed in stainless steel encircle the perimeter with 316 stainless fasteners. Two removable stools, a custom composite table on a fixed base, and composite seat units and cabinets with gelcoated, molded exterior surfaces—each with drains and concealed vents, and bases arranged for drainage and internal storage—underscore thoughtful design. The port‑side hull topside abaft the deckhouse folds down to 90 degrees to form a level beach‑club area flush with the cockpit deck. A hot‑and‑cold shower with mixing valve completes the waterside comfort. All glass in windshields and windows is treated for heat and UV resistance; laminated safety glass is clear at the forward windshield as required and lightly tinted grey elsewhere, with bonded windows finished with a black frit perimeter to conceal and protect adhesive from UV. Three Exalto pantograph wipers on the forward windshield integrate a high‑pressure freshwater wash system.

Miscellaneous

Above‑water thru‑hull fittings are neatly aligned along the boot stripe and painted to match. A chrome‑plated Kahlenberg Model K‑380 airhorn announces your presence with authority. Anchoring is secured by a Lewmar Delta 45 lb. (20 kg) polished stainless steel anchor on a roller assembly that protrudes through the stem for self‑stowing and free‑fall deployment. The rode comprises 65' 7" (20 m) of 8 mm galvanized chain plus 246' (75 m) of 16 mm 8‑plait nylon with stainless steel stop and a 250 mm stainless steel cleat, with a stainless padeye near deck level to secure the bitter end and convenient deck‑hatch access to windlass, rode, and stowage. Cabinetry throughout is engineered to be rattle‑free, with doors and hatches fitted with rubber bump‑stops or gaskets as appropriate. Damping tiles are applied along the chines near the static waterline, and doors are each mounted with three hinges to handle high‑speed shock loads; all door and hatch hardware is flush with surrounding surfaces. Fire protection includes a fixed system—Kidde, Fire‑boy, or equivalent—in the lazarette equipment space with automatic and manual controls and alarms at the main helm or control panel, supplemented by portable extinguishers per USCG requirements. Stainless steel burgee fittings are integrated in the bow rail, with a stern staff socket and a removable staff sized for a 24" x 36" yacht ensign. All FRP hatches feature molded gelcoat inside and out, are supported by one or more gas struts, and include gutter drain lines unless gutters are self‑draining. The composite mast, LPU‑painted to harmonize with its surroundings, has a swept‑back design with swept spreaders ready for radar, antennas, and lighting. Underwater thru‑hulls are bronze or Marelon, each with approved seacocks.
