Trireme 50: expedition Steel Ketch 17m

Maya Zen is a 16-metre steel ketch with an unusually high standard of care. Her hull length is 15,8m, with an overall length of 17m.

From her launch in 1983 until 2021 she belonged to a single Swiss owner, who maintained her with the meticulous discipline characteristic of privately held Swiss-flag vessels.

In 2021 she passed to her second and current owner, who re-registered her under the Polish commercial flag with the intention of operating small, high-latitude charters. As a result, she has benefited from decades of private upkeep followed by recent professional upgrades and improvements.

Built in 6/5/4 mm steel (below waterline-sides-deck) and insulated throughout with XPS panels, she is a genuinely capable expedition yacht. Her construction is straightforward, strong and serviceable. The long keel provides complete protection to the rudder, making her well-suited for remote cruising and colder regions where reliability is essential.

Under sail, Maya Zen has proven to be a surprisingly quick and steady performer. She cruises easily at 8 knots, and on some occasions — when overpowered — she has exceeded 10 knots, demonstrating the efficiency of her hull and rig despite her robust construction.

The interior is one of her most distinctive features: finished in sipo hardwood and with natural fibre linings, it has a warm and inviting character seldom found in modern production yachts. The layout is versatile and practical, offering multiple cabins, including a comfortable aft cabin illuminated by a dome hatch, which brings natural light and gives the space a unique identity.

All mattresses have been newly made to a high standard foam, and the overall impression below deck is one of authenticity, solidity and thoughtful craftsmanship.

Throughout her life, Maya Zen has been maintained consistently and with respect for her original design. She has not been neglected, abandoned or left to decline — quite the opposite: she presents as a vessel whose owners have always invested in her, kept her mechanically sound and structurally healthy. Recent upgrades include modern electrical generation, improved heating and habitability, and various preparations for extended or cold-weather voyaging.

In short, Maya Zen is a rare example of a classic steel expedition yacht that has retained her integrity, her charm and her capability — a solid, honest boat with a clear history and the right foundations for serious cruising.
