Nautilus Yacht Management is proud to present to market this exceptionally well maintained and upgraded example of the celebrated Catana 431. Designed by Christophe Barreau and built by Chantier Catana (FR), SV Altair is hull #08.

SV Altair is a rarely available Catana 431owner's version. Designed as an ocean-voyaging performance catamaran, this Catana 431 combines exceptional quality of built and intelligent features to provide you with safety and speed in all wind conditions, as well as un-matched comfort for a performance catamaran of this size.

SV Altair has been maintained and upgraded to the highest standard and is loaded with high-end upgrades, offshore-ready, and is located in Fiji,  one of the world’s top cruising grounds which permits a tax free sale for non-resident, hence a very popular location for world cruisers coming to the end of their sailing sabbatical.

SV Altair is an ideal cruising catamaran for a couple or family who appreciate the second-to-none intelligent design, quality of build and outstanding performance of a Catana. She comes with a huge inventory and you just need to step aboard and begin your journey. Everything from spare parts, to tools, galley equipment, water toys, full USCG standard safety items, bedding, dinghy and outboard is included.

SV Altair's owners are on board and continue to care for her daily. They will personally handover the boat to her new owners and spend time with them make sure they have time to familiarise themselves with Altair's features and systems. Brizo's remaining cruising period in Fiji is for another 2 years from August 2025, but her owners offer to deliver the boat to Australia or NZ as part of a purchase agreement if required.

A Word From The Owners:

"We purchased this boat in Panama in 2022 and immediately started upgrading this solid foundation of a boat.  All electronics, watermaker, trampoline, and dinghy have all been upgraded to the newest equipment.  We spent two years cruising the Caribbean and then headed back to Panama where we crossed the Panama Canal in early 2025 and crossed to French Polynesia, Samoa and eventually Fiji.  This boat was never chartered and I’m the 2nd owner.   Previously the boat was used in Panama for only a few months a year and had a full-time employee cleaning and taking care of the boat during off season.  This boat is fast with a solid hull.  You will be sailing when all others are motoring as she excels in light air.  Each model of this boat was made to owner specifications with certain options, this one most notably has skegs in front of sail drives to protect sail drives and rudders.  We have been sailing with two children, now teenagers that are now preparing for their college years. "
