2026 Tiara Yachts 39 LS

Twin Mercury 600 hp V12 Verados. Twelve hundred horsepower on the transom of a 39-foot Tiara. This new 2026 Tiara 39 LS, stock #4983, is a serious piece of engineering, and the V12 is the part worth understanding first.

The V12 Verado is unlike any other outboard. The gearcase steers independently of the powerhead, so the engine block stays fixed while only the lower unit rotates. That allows two 600 hp engines to be mounted closer together than conventional outboards and gives remarkable low-speed manoeuvrability, particularly with joystick control. It is also a two-speed transmission, which means strong hole shot and relaxed, quiet cruising rpm. On a 21,339 lb boat, that combination is exactly what you want.

The hull is a proper offshore design: 39 feet on a 12-foot 6-inch beam with a 21-degree transom deadrise. That deadrise figure is the one to note, because it is what lets the 39 LS knife through chop rather than pound across it. With 500 gallons of fuel aboard, the boat has genuine range, enough to make the Lake of the Ozarks feel small and enough for serious coastal cruising if you trailer or ship it.

Systems are set up for real days aboard rather than short hops: 50 gallons of fresh water and 30 gallons of holding, so the head and the freshwater systems support a full day or an overnight without rationing. Bridge clearance is 10 feet 9 inches and draft is 3 feet 5 inches, both worth checking against your own dock and covered slip.

Tiara's LS line is built around the aft-facing social cockpit, so the back of the boat becomes the living space when you stop, with the swim platform, seating, and galley area working together instead of competing.

Why this is the right boat: if you want outboard simplicity and service access but refuse to give up the ride quality, finish, and offshore capability of a built-to-last cruiser, the 39 LS is a rare combination. Twin V12s make it effortless to handle for a couple, and the build quality is why Tiaras stay desirable decades on.

She is new and available at Kelly's Port at the Lake of the Ozarks.
