The Voyager Marine Series 4700 - 1047 2007 vs Voyager Marine Series 5600 - 1456 2007 comparison sits squarely in the category of decisions where specs alone won't tell the whole story: intended use, storage, and long-term ownership costs all factor in.
Size is the most obvious dividing line here. The Voyager Marine Series 5600 - 1456 2007 measures 14,0 feet overall (2007), giving it roughly 4,0 additional feet of deck space compared to the Voyager Marine Series 4700 - 1047 2007 at 10,0 feet (2007). At 80 lbs and 165 lbs respectively, both sit in a similar weight class - either should pair comfortably with most mid-size SUVs and half-ton trucks, though always confirm your specific tow rating with the motor added.
Both boats share a closely matched power ceiling - 2 hp for the Voyager Marine Series 4700 - 1047 2007 and 20 hp for the Voyager Marine Series 5600 - 1456 2007. 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 5600 - 1456 2007 comes in at 8 lbs per hp versus 40 lbs per hp for the Voyager Marine Series 4700 - 1047 2007. 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.
Bottom line: The Voyager Marine Series 5600 - 1456 2007 at 14,0 ft is the right call if deck space, comfort, and entertaining are top of your list. The Voyager Marine Series 4700 - 1047 2007 at 10,0 ft wins on trailering ease, likely lower purchase price, and simpler docking - a solid choice for a buyer who wants more boat for less money.
