Zodiac Medline IV 2011 vs Zodiac Pro Open 650 2008 — Same Brand, Different Boat

Matching a deep vee Zodiac Medline IV 2011 against a inflatable rigid Zodiac Pro Open 650 2008 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 IV 2011 measures 27,9 feet overall (2011), giving it roughly 6,9 additional feet of deck space compared to the Zodiac Pro Open 650 2008 at 21,0 feet (2008). Weight tells a clearer story for trailering families: the Zodiac Medline IV 2011 tips the scales at 3 527 lbs — 2 139 lbs more than the Zodiac Pro Open 650 2008 at 1 388 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 350 hp, the Zodiac Medline IV 2011 has a 175-hp advantage over the Zodiac Pro Open 650 2008's 175-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load.

For family outings this is probably the sharpest distinction between the two. The Zodiac Medline IV 2011 is rated for 8 passengers, while the Zodiac Pro Open 650 2008 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 IV 2011 could be the deciding factor.

Bottom line: Choose the Zodiac Medline IV 2011 if your priority is putting more people on the water — it handles 8 passengers and at 27,9 ft it has the deck room to back that rating up comfortably. The Zodiac Pro Open 650 2008 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 5 that costs less to run day-to-day.

Zodiac Medline IV 2011 vs Zodiac Pro Open 650 2008 — Common Questions

Which is the larger boat — the Zodiac Medline IV 2011 or the Zodiac Pro Open 650 2008?
The Zodiac Medline IV 2011 is the longer of the two at 27,9 feet overall. The Zodiac Pro Open 650 2008 comes in at 21,0 feet, making it roughly 6,9 ft shorter — a meaningful difference in deck room and overall on-water presence.
Which is easier to trailer — the Zodiac Medline IV 2011 or the Zodiac Pro Open 650 2008?
For trailering, the Zodiac Pro Open 650 2008 has the edge at 1 388 lbs dry weight versus 3 527 lbs for the Zodiac Medline IV 2011. Add a motor (typically 300–500 lbs for an outboard in this class), gear, and a partial fuel load and the difference grows. Lighter is friendlier on smaller tow vehicles and on fuel economy while hauling.
Which boat can handle a bigger outboard?
The Zodiac Medline IV 2011 is rated to a maximum of 350 hp, giving it the larger power ceiling. The Zodiac Pro Open 650 2008 tops out at 175 hp. Keep in mind that maximum ratings are just that — matching the motor to the actual load and usage pattern usually matters more than chasing the ceiling.
How many people can each boat hold?
The Zodiac Medline IV 2011 is Coast Guard rated for 8 passengers, while the Zodiac Pro Open 650 2008 is certified for 5. Note that legal capacity and comfortable capacity aren't always the same thing — on a full day out, most experienced boaters aim for about 80% of the rated number to keep things comfortable.
Are the Zodiac Medline IV 2011 and Zodiac Pro Open 650 2008 from the same manufacturer?
Yes — both the Zodiac Medline IV 2011 and the Zodiac Pro Open 650 2008 are built by Zodiac. That means shared dealer networks, common parts availability, and consistent build quality across the line. The choice between them is essentially a question of how much boat you need, not which brand you trust.
