Triple Mercury V12s deliver 1,800 horsepower
The 46 LS is powered by three Mercury 600 V12 Verado outboards, giving the yacht a combined 1,800 horsepower. Tiara integrates the propulsion package with joystick piloting and Garmin Marine navigation, while the helm uses twin Garmin touchscreen displays connected to the vessel’s EmpirBus digital switching system.
That level of integration is aimed at owner-operators who want substantial performance without the operational complexity associated with a larger crewed yacht. The digital helm consolidates navigation and onboard controls while joystick steering simplifies close-quarters manoeuvring during docking.
An enclosed helm extends the usable season
Tiara has given the 46 LS an enclosed helm zone with sliding doors to port and starboard and a vertically retracting aft enclosure. The arrangement allows the central cockpit to operate as a climate-controlled space when weather deteriorates, then reopen when owners want a stronger connection to the deck and water.
For a yacht intended to cover both day boating and longer weekend trips, that flexibility can make a significant difference. Owners are less dependent on consistently warm conditions, while the main social area remains close to the helm instead of dividing passengers between isolated interior and exterior zones.
Three aft modules let owners tailor the deck
The aft cockpit can be configured in three different ways, allowing buyers to prioritise entertaining, adventure equipment or relaxation. A mid-cockpit galley forms part of the social layout, while the portside terrace opens the deck outward to create additional usable space beside the water.
This modular approach gives the 46 LS a different character depending on the owner’s priorities. A family using the yacht for watersports can specify a more equipment-oriented layout, while owners who entertain regularly can concentrate on seating, serving space and direct access to the sea.
Below deck adds genuine weekend accommodation
Below deck, the yacht includes a forward berth, a separate mid-cabin stateroom, a head and additional preparation and pantry space. Tiara lists an overall length of 46 feet 6 inches, a beam of 13 feet 9 inches and a fuel capacity of 660 US gallons.
That combination places the 46 LS firmly in the LYG sector where buyers expect performance, entertaining space and enough accommodation for short cruising without moving into the size and operational requirements of a superyacht. Tiara introduced the model as part of its 2026 model-year expansion and positioned it as a more versatile step within its Luxury Sport range.
