S/V MAITAI is a Río Dulce, Guatemala based 2018 Lagoon 450 S For Sale By Broker. Responses to inquiries may come from a broker who is representing the owner as a fiduciary. This owner requires financial settlement only. No trades.
Introducing the Lagoon 450 S. This remarkable bluewater catamaran has the best of both worlds, combining luxury, performance, and safety wherever you choose to sail. S/V MAITAI is in immaculate condition and stands out as the highly sought-after owner’s version. This vessel has been meticulously cared for by its single owner, who has personally handled the maintenance since its inception. The VAT has also been paid.
S/V MAITAI was sailed from Africa, making the Atlantic crossing and then sailing throughout the Caribbean. Plans were made to make a Pacific crossing, but circumstances prompted a change of plans, so the current owners have reluctantly decided to sell their beloved vessel with everything that is now on board.
In terms of comfort, the Lagoon 450 S does not disappoint. The spacious three-cabin layout features beautiful blond oak interior woodwork complemented by Milano flooring for a modern touch. The well-equipped galley features two INOX 1301 refrigerators for ample food storage. The 220 V microwave oven with grill functionality and new Electrolux Bridgeburner four-burner propane stove with oven make for versatile and easy meal preparation. Other interior features include three heads, each with a shower and a Quiet Flush electric freshwater toilet with efficient solenoid valves. Elegant indirect lighting throughout the cabins and saloon enhances the ambiance. The port and starboard bow sections are outfitted with berths featuring portholes and lighting for cozy sleeping quarters. There are three comfortable ottomans in the saloon, plus an additional ottoman at the owner’s cabin desk. A storage chest in the owner’s cabin replaces the traditional sofa for added utility. There are rear portholes in the aft cabins with curtains for privacy and natural light, and practical leather storage compartments in the cabins for optimal organization. In 2025, a Defy DAW392 washing machine (6 kg) was installed for onboard laundry needs. There are fans in the saloon and cabins for optimal airflow. In 2026, a 12,000 BTU portable air-conditioning unit was installed for comfort in hot and humid conditions.
S/V MAITAI is powered by two perfectly maintained 57 hp Yanmar 4JH57 SD60 engines. The engines have 6,000 hours on them but are in like-new condition and were serviced and fully overhauled in Guadeloupe. It has been noted that these engines could last up to 12,000 hours with continued care. All lower saildrive components are new; the saildrives were serviced three months ago with new seals. The sail inventory consists of a 947 sq ft fully battened mainsail in excellent condition with stack pack, and a 1,399 sq ft headsail with roller furling, also in excellent condition. There are electric winches for easier line management, and all standing and running rigging has been replaced.
This vessel has undergone extensive refurbishments and upgrades, with a significant investment dedicated to its enhancement in South Africa and the Caribbean in 2025. There is a comprehensive list of spare parts and equipment valued at over €100,000 (approx. $116,780.09 USD), with a majority of parts being brand new.
In summary, S/V MAITAI is a turn-key offshore catamaran that offers a unique opportunity for its next owner. With its impeccable condition, extensive upgrades, and luxurious features, this vessel is ready to set sail anywhere you decide to go.
