Introduced in 1992, the Tiara 3100 Open is a complete update of the original 3100 Open built from 1979–91. Her reworked hull features a sharper entry, additional transom deadrise (18 degrees vs. the 14-degrees of the original 3100), greater bow flare for a drier ride, and prop pockets to reduce shaft angles. Significantly, the 3100 Open also has a bi-level cockpit layout that allowed for the installation of optional Volvo, Cat, or Cummins diesels in an enlarged engine compartment. Tiara has always been a conservative builder and it’s no surprise that the new 3100 looks a lot like the original—basically a no-glitz express with top-quality systems, and hardware. The slightly enlarged interior of the new 3100 has a bit more headroom than her predecessor, and there’s also a bigger U-shaped dinette. Additional updates included increased fuel, a tilt-away helm console, recessed trim tabs, and an in-deck fish box and livewell in the cockpit. Note that a transom door became standard in 1994. Early models with 350hp gas engines cruise at 20–21 knots (about 30 knots top), and later models with 330 Cummins diesels cruise efficiently in the mid 20s (30+ knots wide open).
