Zodiac Mark I HD 2009 vs Zodiac Pro Open 650 2011 — Same Brand, Different Boat

Matching a inflatable non rigid Zodiac Mark I HD 2009 against a inflatable rigid Zodiac Pro Open 650 2011 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.

The power gap is worth calling out. Rated to 175 hp, the Zodiac Pro Open 650 2011 has a 150-hp advantage over the Zodiac Mark I HD 2009's 25-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load.

Both boats are rated for 5 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 Zodiac Pro Open 650 2011 at 21,3 ft is the right call if deck space, comfort, and entertaining are top of your list. The Zodiac Mark I HD 2009 at 11,5 ft wins on trailering ease, likely lower purchase price, and simpler docking — a solid choice for a buyer who wants more boat for less money.

Zodiac Mark I HD 2009 vs Zodiac Pro Open 650 2011 — Common Questions

Which is the larger boat — the Zodiac Mark I HD 2009 or the Zodiac Pro Open 650 2011?
The Zodiac Pro Open 650 2011 is the longer of the two at 21,3 feet overall. The Zodiac Mark I HD 2009 comes in at 11,5 feet, making it roughly 9,8 ft shorter — a meaningful difference in deck room and overall on-water presence.
Which boat can handle a bigger outboard?
The Zodiac Pro Open 650 2011 is rated to a maximum of 175 hp, giving it the larger power ceiling. The Zodiac Mark I HD 2009 tops out at 25 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 Mark I HD 2009 is Coast Guard rated for 5 passengers, while the Zodiac Pro Open 650 2011 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 Mark I HD 2009 and Zodiac Pro Open 650 2011 from the same manufacturer?
Yes — both the Zodiac Mark I HD 2009 and the Zodiac Pro Open 650 2011 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.
