The 2015 Tiara Yachts 3100 Coronet is a well-cared-for example of one of Tiara's most versatile and beautifully designed models. Her condition reflects attentive ownership and a consistent level of care throughout. Combining timeless styling, premium construction, diesel performance, and exceptional versatility, the 3100 Coronet offers the open-air entertaining space of a much larger boat while retaining the quality, craftsmanship, and seakeeping for which Tiara Yachts is known.
Powered by twin Volvo Penta D6-330 diesel engines with direct-drive propulsion, she offers a combined 660 horsepower and a proven, straightforward drivetrain. The D6 package provides strong acceleration, an efficient and comfortable cruise, and confident handling. Her substantial 12'6" beam creates a stable platform underway while providing considerably more usable cockpit and interior space than typically found aboard a boat in this size range.
The cockpit is truly the centerpiece of the 3100 Coronet. Tiara designed the boat around entertaining, with generous seating, excellent visibility, an integrated swim platform, and plenty of room for guests to move comfortably throughout the boat. Whether entertaining at the dock, heading out for dinner, cruising the coast, or spending the day anchored with family and friends, the layout is exceptionally functional.
- Desirable twin Volvo Penta diesel package
- 660 combined horsepower
- Direct-drive propulsion
- Wide 12'6" beam
At the helm, the Coronet provides a comfortable and commanding driving position with excellent sightlines and thoughtfully arranged controls and instrumentation. The wide beam and proven Tiara hull design give the boat a solid, confident feel on the water, making her equally enjoyable for a quick afternoon run or a longer coastal trip.
Below deck, the Coronet showcases Tiara's attention to detail and craftsmanship, with quality materials, warm woodwork, comfortable accommodations, a private head, galley amenities, air conditioning and heat, and abundant storage. The interior, cockpit, and mechanical spaces all benefit from the care this vessel has received throughout her ownership.
For a buyer looking for a well-maintained, thoughtfully cared-for Tiara with twin Volvo diesel power, direct-drive reliability, exceptional cockpit space, and genuine overnight capability, this 2015 Tiara 3100 Coronet is an excellent opportunity.
