The Tiara 3100 Open offers a reworked hull features a sharper entry, additional transom deadrise (18 degrees vs. the 16-degree deadrise of the original 3100), greater bow flare for a dryer ride, and prop pockets to reduce shaft angles. Significantly, the 3100 Open also has a bi-level cockpit layout which allows for the installation of the Cat diesels in an enlarged engine compartment. tiara has always been a conservative builder, and it’s no surprise that the 3100 looks a lot like the original – basically a no-glitz express with good-quality construction, systems, and hardware. The slightly enlarged interior of the 3100 has more headroom than before, 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 and transom door.
