When two boats share the same hull type — in this case both the Voyager Marine Series 4700 - 1047 2009 and the Voyager Marine Series 5600 - 1456 2008 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 5600 - 1456 2008 measures 14,0 feet overall (2008), giving it roughly 13,0 additional feet of deck space compared to the Voyager Marine Series 4700 - 1047 2009 at 1,0 feet (2009). Weight tells a clearer story for trailering families: the Voyager Marine Series 5600 - 1456 2008 tips the scales at 165 lbs — 157 lbs less than the Voyager Marine Series 4700 - 1047 2009 at 8 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.

Both boats share a closely matched power ceiling — 2 hp for the Voyager Marine Series 4700 - 1047 2009 and 20 hp for the Voyager Marine Series 5600 - 1456 2008. Real-world performance will come down more to which motor is actually bolted on, its load at the time, and whether it's a 4-stroke or 2-stroke setup.

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 4700 - 1047 2009 comes in at 4 lbs per hp versus 8 lbs per hp for the Voyager Marine Series 5600 - 1456 2008. 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.
