Owner’s Version | Carbon Mast and Boom | 2022 Yanmar Engines | Lithium and Victron Power | Replacement Standing RiggingMOTIVATED SELLERIntroductionBLUE MOON is the highly sought-after Owner’s Version of the Catana 581, a yacht widely respected for combining genuine offshore performance with exceptional comfort for long-distance cruising and liveaboard life.Built using Catana’s lightweight foam-sandwich composite construction with carbon reinforcement in high-load areas, carbon spars and lifting daggerboards, she delivers the sailing performance for which the Catana name is renowned while providing spacious, practical accommodation for extended cruising.Extensively upgraded under her current ownership, BLUE MOON benefits from twin 2022 Yanmar 110HP engines, a 2022 Onan generator, replacement standing rigging, recent Crusader sails, Gori folding propellers, an extensive Victron lithium electrical system, approximately 2.25kW of solar generation, Starlink High Performance satellite communications, a Seawater Pro watermaker and numerous mechanical, electrical and structural improvements completed during 2025 and 2026.Following these upgrades, she completed an Atlantic crossing from Greece to Trinidad in early 2026 before continuing safely through the Caribbean to Cartagena, demonstrating the offshore capability for which the Catana 581 has earned its reputation as a highly regarded bluewater performance cruising catamaran.For buyers seeking a proven offshore cruising yacht, BLUE MOON represents an opportunity to acquire a particularly well-equipped Catana which has benefited from substantial recent investment in her machinery, rigging, electrical systems and structure.Broker’s CommentsBLUE MOON was acquired by her current owner in August 2025 following a pre-purchase survey and has since benefited from substantial mechanical, electrical, rigging and structural investment.Replacement standing rigging was completed in Greece during October 2025. Professional composite repairs to the port coachroof-to-bulkhead connection and an adjoining section of the forward deck were completed in May 2026 using epoxy, carbon fibre, Nida core and biaxial fibreglass construction in accordance with the contractor’s documented lay-up schedule. This was followed by an independent rig inspection in June 2026.The exterior teak has also recently been resanded and stained, substantially improving its presentation.BLUE MOON is currently benefiting from a further programme of routine maintenance and refurbishment, including mechanical servicing, electrical work, air-conditioning maintenance, local cosmetic fibreglass and gelcoat repairs, joinery and stainless-steel work, together with removal and rebedding of a saloon window to address a minor leak. The seller expects this programme to be substantially completed before returning to the yacht in October 2026.Importantly, a comprehensive documentation package accompanies BLUE MOON. This includes the July 2025 pre-purchase survey, a detailed current reconciliation of the survey observations and subsequent works, together with contractor invoices, structural documentation, rigging certification and other supporting technical records.This survey, reconciliation and supporting technical documentation are available to genuinely interested purchasers upon request.Highlights
