Bali 4.3 MY, Bali's First Production Power Catamaran

How the Bali 4.3 MY came about

The Bali 4.3 MY is the motor yacht version of Bali's 43-foot sailing catamaran, and Multihulls World described it as the brand's first production power cat. The project started with a prototype in 2017. Early runs with Nanni power and Xavier Faÿ's hulls, the magazine reported, gave very encouraging results for performance and fuel economy, and it then took about two years of work to get from prototype to finished boat. The production version was first presented at the International Multihull Show in April 2019.

Bali, part of the Catana Group, chose a modest 43 feet for this first step, the size where its sailing range had been most successful. Multihulls World was clear that this is not just a sailing hull with the mast removed: the 4.3 MY is based on the 4.3 but heavily redesigned, and the magazine called the conversion a real transformation into a brand-new boat.

What carried over from the sailing Bali

The features that made Bali famous are all here. The signature tilting garage-style door opens the saloon completely to the aft deck, a second door leads directly from the saloon to the forward cockpit, and the solid foredeck replaces trampolines with a large lounging area. The dining area seats up to ten. On a power cat, that rigid foredeck is a natural fit, and Multihulls World highlighted the high, clear tunnel between the hulls as a key asset in rough seas.

Two details are specific to the MY. The aft cabins open directly onto the aft deck, which is convenient for swimmers and for guests who want privacy from the saloon. And a hydraulic tender lift platform with a remote control replaces the davits used on the sailing boats. LASTA Design handled the styling, with Olivier Poncin and Yann Chabaud credited with the concept.

The MY against the sailing 4.3, side by side

On paper the two boats share a beam of 7.12 meters and the same naval architect, but the MY is a different animal. Its light displacement is about 12.7 tonnes on the dealer sheet against 11.3 tonnes for the sailing 4.3, and its listed draft is about 0.90 meters against 0.95 for the sailboat. Standard fuel is the same 800 liters as the sailing boat, but the MY offers a 1,600-liter option that the sailboat never needed.

For a sailing-cat owner thinking of switching, the appeal is obvious: no rig, sails or winches to maintain, the same open Bali living spaces and a tunnel designed for powering into a sea. The trade is engine hours, since every mile is made under power.

Specifications, and where the sources disagree

Published data for the Bali 4.3 MY is thinner than for the sailing boats, and the two main sources do not fully agree. A dealer specification sheet from Catamaran Guru lists 42.42 feet (12.93 meters) overall, a 23.4-foot beam, 2 feet 11 inches of draft, about 12.7 tonnes light and 18.6 tonnes maximum displacement, and twin 160 hp engines. Multihulls World's technical sheet lists 13.10 meters overall, 13 tonnes and twin 250 hp engines.

Both agree on 800 liters (211 gallons) of water, 800 liters of fuel with an optional 1,600-liter (423-gallon) tank, a 7.12-meter beam, CE Category A for 12 people and Xavier Faÿ as naval architect. We could not confirm whether more than one power package was offered or which boats carry which engines, so treat every listing's engine claim as something to verify against the serial plates.

• Length overall: 42 ft 5 in (dealer sheet) or 43 ft (Multihulls World)
• Beam 23 ft 4 in; draft about 2 ft 11 in
• Fuel 211 gal standard, 423 gal optional; water 211 gal
• Fridge and freezer capacity 620 liters
• Engines: twin 160 hp or twin 250 hp depending on source

Two, three or four cabins

Bali offered the 4.3 MY in two-, three- and four-cabin layouts, which is unusually flexible for a 43-foot power cat. The two-cabin version suits a couple who want enormous hull-length suites; the three-cabin owner layout follows the sailing 4.3 with a full owner's hull; and four cabins point to charter. The 620-liter fridge and freezer capacity, generous for this size, reflects the long-stay brief.

Ask any seller for the original layout drawing and confirm what the boat actually has, since layout drives both comfort and resale, and check whether the aft cabins' direct deck doors seal properly.

Performance, without inventing numbers

We did not find a published speed and fuel table for the production Bali 4.3 MY. Multihulls World's test was framed around whether the boat had inherited the prototype's encouraging economy, and its sea trial summary praised the concept, but the detailed figures sit behind the magazine's paywall. Bali's own archive references a sea trial published by Croatia's Burza Nautike, which we were unable to retrieve.

Without verified numbers, the most useful clue is the optional double tankage, which suggests Bali expected owners to cover long distances at economical speeds rather than to run fast. On any sea trial, log rpm, speed and fuel flow at three steady settings so you know what you are buying, and compare the results with the engines actually fitted.

Buying a used Bali 4.3 MY

The 4.3 MY is no longer in Bali's lineup, which in 2026 consists entirely of sailing catamarans from the Catsmart to the 7.0. Bali's website later carried a Catspace MY page, but there is no current Bali power cat to compare against, so the 4.3 MY is a niche used purchase with few comparables.

Because we could not find recent public asking prices, we estimate $350,000 to $520,000, placed slightly above the sailing 4.3 because the MY boats are newer and carry larger engines and more tankage. Running costs, including insurance, dockage for a 23-foot beam, engine service on two diesels, generator and bottom work, typically run $35,000 to $65,000 a year before fuel. Check whether the boat has been imported and duty paid if it is in US waters.
