2023 Viaggio Diamante 23B

Smart styling and a luxurious ride.

Just like the name (the Italian word for voyage or journey), Viaggio’s Diamante 23B has its own unique style. Find it in the perimeter rails, heavy-duty 3-inch-wide aluminum extrusions with precise angled corners meant to evoke the angles of the letter V. See it in flat-panel aluminum walls that combine an attractive matte finish with the subtle pop of metallic flake. Note that blackout isn’t an optional package name but the standard finish to metalwork abovedecks.

Step aboard and accommodations build on that initial impression. Lounges feature angular corners and a clean, minimalist color scheme, with vinyl wrapping the seat bases all the way to the floor. Roto-molded seat bases feature water-diverting channels to keep water at bay. Two-part hinges allow cushions to pivot down and perpendicular, making it easier to access gear. There’s also impressive attention to detail. Seat-base-mounted speakers are covered in housings, wiring wrapped in conduit, and screws covered with protective plastic tips.

At the helm, a standard Simrad Go9 dominates the dash, keeping GPS positioning and engine data front and center. Aircraft-style toggles for lights, the horn, bilge and the like are grouped to the left and right of the wheel. Aft, the layout is highlighted by a slender bar. Enjoy drinks seated on one of three stools featuring gleaming stainless-steel backrests. Drink holders smartly hold both cans and stemware. There’s also designated can and bottle storage, a bottle opener and USB charging. Note the design smartly angles aft midway along its length to maintain easy stern access. Opposite, add a trio of passengers on another comfy couch, or stretch out solo against an aft-facing backrest.

Our test boat’s Suzuki 200 was noticeably quiet, registering only 52 dB(A) at idle and 82 dB(A) at the boat’s 40.8 mph top speed. Optional triple 25-inch pontoons with performance-minded lifting strakes produced sharp handling while retaining more of a pontoon’s classic, flatter-turning personality. An efficient cruise was noted at 3,000 rpm and 16.5 mph, a combo that burned a minimal 3.4 gph.
