KOS 58.CAT

Bali launched the 5.8 in 2024 as the tenth-anniversary flagship of the range, and KOS 58.CAT is a 2025 hull working her first full season out of Athens. She is a 17.65-metre sailing catamaran with 9.06 metres of beam, built by the Catana Group with carbon structural bulkheads borrowed from the parent yard's racing programme.

The Bali signature is the forward cockpit, a full social lounge across the foredeck, and the 5.8 puts it on a scale that handles the whole charter party. The aft cockpit, the saloon, and the foredeck lounge form one continuous deck on the same level, with the garage-style transom dropping to make the swim platform an extension of the cockpit. Twin diesels of 80 horsepower each push her at sensible cruise; the rest is sail.

Twelve guests sleep in six en-suite cabins on a hull configured for two families or three couples and friends. The galley sits in the saloon at standing height with the sliding doors open onto the cockpit, which is how dinner ends up running long after sunset. Bimini, water maker, ice maker, and solar make her self-sufficient at anchor for a full week.

Alimos Marina is the home base year-round. The Cyclades fill the summer schedule, with Hydra, Spetses, and the Saronic Gulf taking over once the meltemi drops in autumn. Two stand-up paddleboards, snorkel gear, and fishing gear ride on board, all launched from the swim platform.
