Both the Voyager Marine Series 5600 - 1456 2009 and the Voyager Marine Series 8500 2010 are flat-bottom designs, both built in aluminium, so 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?

On paper these two are close siblings in the size department - Voyager Marine Series 5600 - 1456 2009 at 14,0 ft versus Voyager Marine Series 8500 2010 at 16,0 ft. Weight tells a clearer story for trailering families: the Voyager Marine Series 8500 2010 tips the scales at 430 lbs - 265 lbs less than the Voyager Marine Series 5600 - 1456 2009 at 165 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 - 20 hp for the Voyager Marine Series 5600 - 1456 2009 and 40 hp for the Voyager Marine Series 8500 2010. 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 2009 comes in at 8 lbs per hp versus 11 lbs per hp for the Voyager Marine Series 8500 2010. 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.
