Design and Construction
Bali Catamarans built the 4.1 in Canet-en-Roussillon, with the design credited to Olivier Poncin and Xavier Faÿ. The hulls are foam-cored and vacuum-infused, and a hard chine runs the length to deflect spray while lending a little extra interior volume below anchor. Rather than the daggerboards of Catana's sportier multihulls, the 4.1 carries fixed keels bolted into watertight recesses at the hull bottoms, and those same recesses double as graywater holding tanks. A solid foredeck acts as a structural member in its own right, and the nacelle is set high and angled to soften pounding when the boat works to windward. Reviewers in Multihulls World noted that perceived build quality was progressing on this generation, and the ski-shape forward sections with their tunnel effect were called the boat's major design accomplishment, with early doubts about the bold bow form since disproved by service experience across the range.
Rig and Handling
The helm sits to starboard and is best described as an elevated steering station rather than a full flybridge. Up forward, a Z-Spars single-spreader aluminum mast carried 1,135 square feet of Elvstrøm canvas on the test boat, built around a self-tacking solent on a furler that sheets to a cabintop track just ahead of the mast. A bowsprit provides the tack point for a Code 0 or spinnaker. Multihulls World found the boat agile, manageable, and pleasant even under just main and solent, with good dynamic manners in breezes under 15 knots, and SAIL Magazine's testers recorded flat-water motoring at 6.5 knots turning 2,000 rpm, rising to just over 8 knots at wide-open throttle of 3,000 rpm anchor.
Accommodations
The 4.1's interior is where the design takes its leap forward. A cantilevered glass-and-composite door lowers from the cabintop to fuse the forward cockpit with the saloon, and it is light enough for a small crew to operate by hand. Forward of that threshold lies an L-shaped dinette to port and a stand-up Liebherr fridge to starboard, with the galley and its Eno stove beyond, a corner nav desk, and a manually lowered window so the cook can pass drinks to the forward lounge. That forward lounge itself seats six, with a U-shaped settee and table for five at cocktail hour. Aft, a fixed platform bridges the hulls so one can walk bow to stern without entering the cockpit, and the revised davit system opened space for an integrated transom seat outside the main cockpit, flanked by enlarged side lockers, one of which can house an optional grill. Below, buyers choose among four layouts: a four-cabin, four-head charter plan, a three-cabin three-head version, or three cabins with two heads where the port-side owner's suite holds a large aft double, a desk amidships, and a separate shower stall in the forepeak. The Maxi Lounge treatment emphasizes abundant light and complementary spaces suited to all climates.
Equipment and Systems
Tankage is generous for the size: 110 gallons of diesel and 221 gallons of water. Auxiliary power on the reviewed boat came from a pair of 40-horsepower Volvo Penta diesels driving saildrives, and Multihulls World praised the exemplary access to the engine compartments. The davits are simple and smart in concept, though the test report noted the dinghy must be hoisted with its outboard removed and then stored resting at an angle on one tube.
The Verdict
The Bali 4.1 is a thoughtfully evolved cruising cat that trades ultralight performance for liveaboard comfort and charter-ready practicality. Its rigid foredeck, fixed-keel watertight recesses, and sliding door saloon are distinctive solutions, and the boat handles easily under reduced canvas. The aft profile is functional rather than pretty, and the dinghy stowage demands removing the outboard, but the accommodation volume and access to machinery are strong selling points.
Pros
- Rigid solid foredeck adds structural rigidity and eliminates hull twisting
- Self-tacking solent and bowsprit rig make short-handed sailing manageable
- Cantilevered door merges saloon and forward cockpit with minimal effort
- Four belowdecks layouts including a spacious three-cabin owner's suite
- Exemplary engine-compartment access and large water and fuel capacity
Cons
- Aft view is functional but visually harsh per period review
- Dinghy davits require outboard removal and angled single-tube stowage
- Helm station is not a true flybridge despite its elevated position
