When two boats share the same hull type — in this case both the Mercury DR570 2008 and the Mercury V620 PVC 2010 are inflatable rigid designs with inflatable construction — 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 — Mercury DR570 2008 at 18,0 ft versus Mercury V620 PVC 2010 at 20,2 ft. Weight tells a clearer story for trailering families: the Mercury V620 PVC 2010 tips the scales at 1 071 lbs — 254 lbs less than the Mercury DR570 2008 at 817 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 Mercury DR570 2008 and 150 hp for the Mercury V620 PVC 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.
For family outings this is probably the sharpest distinction between the two. The Mercury V620 PVC 2010 is rated for 17 passengers, while the Mercury DR570 2008 caps at 15. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Mercury V620 PVC 2010 could be the deciding factor.
Bottom line: Choose the Mercury V620 PVC 2010 if your priority is putting more people on the water — it handles 17 passengers and at 20,2 ft it has the deck room to back that rating up comfortably. The Mercury DR570 2008 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 15 that costs less to run day-to-day.
