Matching a deep vee Zodiac Medline III 2011 against a inflatable rigid Zodiac Pro 650 2010 means you're likely deciding between two genuinely different on-water experiences. Hull type shapes everything from ride quality and fuel burn to dock handling and resale trajectory.
Size is the most obvious dividing line here. The Zodiac Medline III 2011 measures 24,0 feet overall (2011), giving it roughly 3,3 additional feet of deck space compared to the Zodiac Pro 650 2010 at 20,7 feet (2010). Weight tells a clearer story for trailering families: the Zodiac Medline III 2011 tips the scales at 3 087 lbs — 1 830 lbs more than the Zodiac Pro 650 2010 at 1 257 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.
The power gap is worth calling out. Rated to 250 hp, the Zodiac Medline III 2011 has a 100-hp advantage over the Zodiac Pro 650 2010's 150-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Both carry nearly identical fuel loads — 47 gal and 48 gal — so range won't be a tiebreaker here.
For family outings this is probably the sharpest distinction between the two. The Zodiac Medline III 2011 is rated for 8 passengers, while the Zodiac Pro 650 2010 caps at 5. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Zodiac Medline III 2011 could be the deciding factor.
Bottom line: Choose the Zodiac Medline III 2011 if your priority is putting more people on the water — it handles 8 passengers and at 24,0 ft it has the deck room to back that rating up comfortably. The Zodiac Pro 650 2010 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 5 that costs less to run day-to-day.
