The Voyager Marine 2070SC 2010 is a flat-bottom design and the Voyager Marine 22 Supreme Fish and Cruise 2009 is a pontoon design, so you're likely deciding between two noticeably different on-water experiences. Hull type shapes everything from ride quality and fuel burn to dock handling and resale trajectory.
On paper these two are close siblings in the size department - Voyager Marine 2070SC 2010 at 19,9 ft versus Voyager Marine 22 Supreme Fish and Cruise 2009 at 22,0 ft. Weight tells a clearer story for trailering families: the Voyager Marine 22 Supreme Fish and Cruise 2009 tips the scales at 1 700 lbs - 550 lbs less than the Voyager Marine 2070SC 2010 at 1 150 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 - 135 hp for the Voyager Marine 2070SC 2010 and 115 hp for the Voyager Marine 22 Supreme Fish and Cruise 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 22 Supreme Fish and Cruise 2009 is rated for 12 passengers, while the Voyager Marine 2070SC 2010 caps at 6. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Voyager Marine 22 Supreme Fish and Cruise 2009 could be the deciding factor.
Bottom line: Choose the Voyager Marine 22 Supreme Fish and Cruise 2009 if your priority is putting more people on the water - it handles 12 passengers and at 22,0 ft it has the deck room to back that rating up comfortably. The Voyager Marine 2070SC 2010 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 6 that costs less to run day-to-day.
