With a light load and two aboard, we topped at nearly 48 mph by GPS. The boat loped along easily at 4,000 rpm while turning 30.3 mph. Factory tests with four aboard and half a tank of fuel produced a top speed of 44.8 mph at 6,100 rpm. At 3,500 rpm, the economy pace generated a speed of 24.2 mph with a fuel rate of 1.49 mpg. The super-stable hull rides as solid as an aircraft carrier, even in a beam sea, with noteworthy handling. The power-assisted steering lets the operator respond quickly to course corrections, and while you couldn’t expect a boat this size to turn on a dime, a quarter is not an exaggeration. Unlike some other catamarans, the 320DC holds level and true in turns without leaning. The integrated hardtop with bow walk-through offers good visibility and shelter from the elements in addition to a sporty profile. A curtain package with Strataglass and underside colors to match the hull are available options.
