The 2021 Fountaine Pajot Isla 40 "Monarch" is a well-equipped Owner's Version (3 cabin / 3 head) that entered service in January 2022 and proved her pedigree with an Atlantic crossing on her own hull. Powered by twin Volvo D1-30F engines and complemented by a factory-installed 7.5 kW Onan/Cummins generator, she offers full climate control with three-zone air conditioning, a 2000W Victron inverter/charger, and a robust US-spec electrical system with 50-amp shore power. The sought-after starboard owner's hull features a queen berth aft, private electric head, and separate walk-in shower, while the port hull provides two additional en-suite cabins - making her equally suited for private cruising or charter. Outfitted with the Isla Comfort Pack, upgraded Bose audio, Garmin navigation suite with radar and AIS, electric winch and windlass, pressurized seawater system, extensive anchoring gear including Mantus hardware and dual chain rodes, plus a 2025 Highfield tender with Mercury 5HP outboard, Monarch presents as a turnkey cruising catamaran ready for her next adventure.
