Both the Voyager Marine 1870CC 2010 and the Voyager Marine All Welded Jons - Center Console 2012 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 1870CC 2010 at 18,3 ft versus Voyager Marine All Welded Jons - Center Console 2012 at 18,3 ft. At 860 lbs and 860 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 - 115 hp for the Voyager Marine 1870CC 2010 and 115 hp for the Voyager Marine All Welded Jons - Center Console 2012. 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 6 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.
Bottom line: The Voyager Marine 1870CC 2010 and Voyager Marine All Welded Jons - Center Console 2012 are closely matched on the specs that matter most. Test-ride both on the water you actually use, check current dealer pricing, and factor in long-term service access before you sign.
