Both the Voyager Marine Series 7000 - 1670 2009 and the Voyager Marine Series 8500 - 1885 Open 2009 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 7000 - 1670 2009 at 16,0 ft versus Voyager Marine Series 8500 - 1885 Open 2009 at 18,0 ft. Weight tells a clearer story for trailering families: the Voyager Marine Series 8500 - 1885 Open 2009 tips the scales at 500 lbs - 225 lbs less than the Voyager Marine Series 7000 - 1670 2009 at 275 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 - 35 hp for the Voyager Marine Series 7000 - 1670 2009 and 40 hp for the Voyager Marine Series 8500 - 1885 Open 2009. 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.

For family outings this is probably the sharpest distinction between the two. The Voyager Marine Series 7000 - 1670 2009 is rated for 3 passengers, while the Voyager Marine Series 8500 - 1885 Open 2009 caps at 2. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Voyager Marine Series 7000 - 1670 2009 could be the deciding factor.

At this size, power-to-weight ratio matters more than outright horsepower. The Voyager Marine Series 7000 - 1670 2009 comes in at 8 lbs per hp versus 13 lbs per hp for the Voyager Marine Series 8500 - 1885 Open 2009. 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.
