When two boats share the same hull type — in this case both the Voyager Marine 56 Series 2012 and the Voyager Marine Series 8500 2010 are flat designs with aluminum construction — the buying decision usually comes down to a handful of practical questions: how many people are you putting on the water, how far do you trailer, and what does your tow vehicle weigh?

Size is the most obvious dividing line here. The Voyager Marine Series 8500 2010 measures 16,0 feet overall (2010), giving it roughly 4,0 additional feet of deck space compared to the Voyager Marine 56 Series 2012 at 12,0 feet (2012). Weight tells a clearer story for trailering families: the Voyager Marine 56 Series 2012 tips the scales at 145 lbs — 102 lbs more than the Voyager Marine Series 8500 2010 at 43 lbs. That difference is meaningful if you're working within a half-ton or three-quarter-ton truck's tow rating, especially once you factor in a motor, gear, and fuel.

The power gap is worth calling out. Rated to 40 hp, the Voyager Marine Series 8500 2010 has a 30-hp advantage over the Voyager Marine 56 Series 2012's 10-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load.

Both boats are rated for 3 passengers — a good fit for a family of four or five plus guests. Comfort at capacity is another matter; the longer hull typically means more seat options and better weight distribution.

At this size, power-to-weight ratio matters more than outright horsepower. The Voyager Marine Series 8500 2010 comes in at 1 lbs per hp versus 15 lbs per hp for the Voyager Marine 56 Series 2012. The lower the ratio the more explosive the acceleration — meaningful on a short RIB where bursts of speed, quick planing, and agility in surf or tight waterways define the experience.
