Zemi answers a specific request: a 110 foot carbon sloop quick enough to make passages interesting, and calm enough to carry a family across an ocean without anyone thinking about it. Her owner had sailed enough to know the difference.
Malcolm McKeon drew her, working again with A2B Marine Projects after the pair delivered Baltic 112 Liara. The result is a versatile performance cruiser rather than a stripped racer: twin rudders for control at angle of heel, a lifting keel that swings draft between 3.8 and 5.8 metres, and 95 tonnes of displacement kept honest by an all-carbon structure.
Propulsion is where she departs from convention. Zemi is the third Baltic to run electric drive, a lithium-ion powered Danfoss motor turning a conventional shaft. It is quieter and smoother than a diesel, emits nothing at the point of use, and reverses its role under sail as the free-wheeling propeller regenerates into the battery bank. Twin 129 kW Cummins generators meet IMO Tier 3, so the support systems match the ambition.
Andreas Martin-Loef Arkitekter designed the interior from Stockholm, and it carries that studio’s restraint: quiet materials, considered proportion, nothing competing for attention. Aft, a multi-function transom folds down into a beach club, and the tender lives in a stern garage rather than cluttering the deck.
Delivered in 2023, Zemi shows the current Baltic thinking on how a family cruiser at this size should work.

A sloop built to cruise and to race, and never forced to choose between the two.
Twin rudders hold her steady at an angle of heel that would unsettle a less considered design, while a telescopic lifting keel swings draught between 3.8 and 5.8 metres, opening anchorages a fixed-keel yacht of this size would have to avoid. The sail wardrobe is built for quick changes rather than a single ideal condition: fixed furling J1 and J2, a detachable storm jib stay, and a furling Code sail set forward of the J1, with a run of A-sails launched from a bowsprit built into the hull moulding itself. It is a rig designed to be reconfigured mid-passage, not reset at the dock.
The drivetrain is where Zemi actually breaks from convention.
A 247kW Danfoss motor drives a four blade folding propeller directly, with no gearbox and none of the hydraulics a controllable pitch system would need, a saving in weight as much as complexity. Twin 129kW generators charge a lithium-ion battery bank that supplies the propulsion motor along with every domestic, hydraulic and rig handling system aboard, and the same folding propeller freewheels into a generator while she sails, feeding the batteries back up without burning a litre of diesel. She is the third Baltic to run this electric architecture, and the result is a yacht that is markedly quieter and smoother under power than an equivalent diesel sloop, with zero emissions at the point of use.
Her hull is finished in metallic bronze, a colour few yards would risk on a yacht this size.
Vertical coachroof windows and a deliberately low superstructure keep the profile lean, while McKeon’s signature wrap-over teak decking runs unbroken from the main deck onto the transom. The cockpit, teak skinned like the rest of the deck, converts into a full sun lounging area under a combined fold-down spray hood and removable bimini, useful in both the Arctic and the tropics given the itinerary she was built for. Aft, a fold-out transom opens the bathing platform onto a stern garage sized for a Williams tender, keeping the water toys out of sight until they are needed.
Andreas Martin-Loef Arkitekter brought a Scandinavian hand to a build obsessed with saving weight.
Walnut runs through the interior as veneer bonded to ultra lightweight honeycomb cores, and the same discipline extends into the heads, where limestone veneers sit on equally light carcasses rather than solid stone. Lantern style fittings in Japanese rice paper and walnut strips soften the saloon corners, while light sources set into panel divides and generous coachroof skylighting keep the mood calm rather than cave like below decks. Nothing competes for attention. It is an interior built around restraint, proportion and the discipline of carrying as little unnecessary weight as a Scandinavian studio could manage.
Built at Baltic’s Bosund facility and launched at Jakobstad, Zemi carries the yard’s full engineering pedigree into her first ocean crossings.
She measures 33.5 metres (109.9 feet) on a 7.6 metre beam, with displacement held to 95 tonnes and a draught of up to 5.8 metres on the raised keel. Malcolm McKeon Yacht Design drew the naval architecture and exterior, with Andreas Martin-Loef Arkitekter responsible for the interior, the same partnership behind Baltic’s 112 Liara. Delivered in 2023, she was built for an itinerary that runs from Svalbard and the Canaries to the Caribbean and on toward a Pacific crossing, proof that an electric sailing superyacht can cover real distance, not just make a point at anchor.
