GRANOCEAN W-72 "Roy Cay" Full Power Catamaran Walkthrough | 26.7 Knots, Twin CAT C18s

26.7 knots on a 72-foot power catamaran. This is the GranOcean W-72 "Roy Cay" a fully-equipped $4.5-5M semi-custom build shot in Fort Lauderdale before delivery to its owner in the Bahamas. Jeremy walks through every feature and system on this top-spec W-72, featuring twin Caterpillar C18 engines delivering 2,300 combined horsepower, a fully integrated 48V lithium power system with 3,000 watts of solar, and an upgraded Frigomar air conditioning package that runs hotel loads including AC for 2 to 3 days at anchor with no generator. 00:00 Unique Features and Specs 00:58 The Foredeck/Sidedecks/Gelcoating 02:05 Tender Lift Platform and Fuel Station 02:46 Flybridge / Helm / Garmin Displays / Space 03:37 Signature Flybridge Wings / Custom Steel Retention System 03:58 Engine Rooms / Superior Access Hatch Design 05:26 Salon, Galley Up Configuration, Scandinavian Vripack Design 07:16 Owner's Cabin, Guest Cabins, Heads and Crew Cabins 10:45 Navigation Station / Camera System / Speed 12:07 Automatic Blinds / Aft Cockpit Bar and Television 12:59 Lithium Batteries / Battery Management System / Termodinamica AC 13:51 DC Panel System / 24 Volt DC Panel Power Management 15:41 Termodinamica Air Conditioning System Upgrade / MG Battery Management System / Inverters 17:16 Pricing of Roy Cay The Termodinamica air conditioning upgrade paired with MG battery management is the single spec that transforms how Roy Cay is lived on. This owner upgraded to a Termodinamica, the Italian specialist brand that builds variable-speed DC air conditioning specifically for off-grid yacht use. Paired with the MG battery management system orchestrating a 48V lithium bank and 3,000 watts of solar, every compressor, fridge, and light runs off a single integrated hotel-load bus. No startup surges, no cycling losses, no AC-to-DC conversion penalty. The result is tested, not theoretical: 4 to 8 hours of full hotel load including air conditioning on battery alone, and 2 to 3 days at anchor before the generator needs to come on. For a boat that cruises the Bahamas and Caribbean, this is the difference between a floating hotel tied to its machinery and a genuine off-grid retreat. Silent nights. Zero diesel vibration. No 3 AM generator cycles to keep the cabins cool. It is the system that turns a premium power catamaran into something that actually lives up to the word "cruising."
