The 2012 Tiara 3900 Open is a 39-foot cruiser built on a fiberglass hull and powered by twin Cummins diesel engines producing 1,200 horsepower combined. With a cruising speed of 27.6 knots and a beam of 15 feet, the boat delivers capable performance and generous interior volume. The engines have logged only 650 hours of operation.
The open design prioritizes outdoor entertaining around the helm and cockpit. A hardtop with full enclosure shelters the helm area, while a cockpit sunshade with carbon fiber poles provides additional weather protection. The swim platform is fiberglass, and the boat is equipped with a bow thruster and anchor windlass for docking and anchoring ease.
Below deck, the cabin sole is solid teak and holly. The forward stateroom includes a centerline berth and entertainment center. The saloon features wrap-around seating with a table that converts for additional berthing space. A full galley is positioned to port. One head serves the accommodations.
Navigation and communication equipment includes Simrad autopilot, an Icom VHF marine radio, and an ACR remote spotlight. New Furuno electronics were installed in 2025, comprising chartplotter, radar, and sounder.
