Zodiac Cadet Solid 285 2011 vs Zodiac Classic Mark I Solid 2013 — A Close Look at Two Inflatable Non Rigids

When two boats share the same hull type — in this case both the Zodiac Cadet Solid 285 2011 and the Zodiac Classic Mark I Solid 2013 are inflatable non 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 — Zodiac Cadet Solid 285 2011 at 9,3 ft versus Zodiac Classic Mark I Solid 2013 at 11,5 ft. At 86 lbs and 134 lbs respectively, both sit in a similar weight class — either should pair comfortably with most mid-size SUVs and half-ton trucks, though always confirm your specific tow rating with the motor added.

Both boats share a closely matched power ceiling — 8 hp for the Zodiac Cadet Solid 285 2011 and 25 hp for the Zodiac Classic Mark I Solid 2013. 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 Zodiac Classic Mark I Solid 2013 is rated for 5 passengers, while the Zodiac Cadet Solid 285 2011 caps at 4. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Zodiac Classic Mark I Solid 2013 could be the deciding factor.

At this size, power-to-weight ratio matters more than outright horsepower. The Zodiac Classic Mark I Solid 2013 comes in at 5 lbs per hp versus 11 lbs per hp for the Zodiac Cadet Solid 285 2011. The lower the ratio the more explosive the acceleration — meaningful on a short RIB where bursts of speed, quick planing, and agility in surf or tight waterways define the experience.

Top speed is rated at 28 mph for the Zodiac Classic Mark I Solid 2013 and 17 mph for the Zodiac Cadet Solid 285 2011.

Bottom line: Choose the Zodiac Classic Mark I Solid 2013 if your priority is putting more people on the water — it handles 5 passengers and at 11,5 ft it has the deck room to back that rating up comfortably. The Zodiac Cadet Solid 285 2011 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 4 that costs less to run day-to-day.

Zodiac Cadet Solid 285 2011 vs Zodiac Classic Mark I Solid 2013 — Common Questions

Which is the larger boat — the Zodiac Cadet Solid 285 2011 or the Zodiac Classic Mark I Solid 2013?
The Zodiac Classic Mark I Solid 2013 is the longer of the two at 11,5 feet overall. The Zodiac Cadet Solid 285 2011 comes in at 9,3 feet, making it roughly 2,2 ft shorter — a meaningful difference in deck room and overall on-water presence.
Which is easier to trailer — the Zodiac Cadet Solid 285 2011 or the Zodiac Classic Mark I Solid 2013?
For trailering, the Zodiac Cadet Solid 285 2011 has the edge at 86 lbs dry weight versus 134 lbs for the Zodiac Classic Mark I Solid 2013. 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 Classic Mark I Solid 2013 is rated to a maximum of 25 hp, giving it the larger power ceiling. The Zodiac Cadet Solid 285 2011 tops out at 8 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 Cadet Solid 285 2011 is Coast Guard rated for 4 passengers, while the Zodiac Classic Mark I Solid 2013 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.
Which is faster — the Zodiac Cadet Solid 285 2011 or the Zodiac Classic Mark I Solid 2013?
The Zodiac Classic Mark I Solid 2013 has the higher rated top speed at 28 mph, versus 17 mph for the Zodiac Cadet Solid 285 2011. Real-world speeds depend on motor choice, load, water conditions, and how you run the throttle — rated speeds are achieved under ideal test conditions.
Which boat has the better power-to-weight ratio?
The Zodiac Classic Mark I Solid 2013 has a better power-to-weight ratio at 5 lbs per hp compared to 11 lbs per hp for the Zodiac Cadet Solid 285 2011. A lower number means quicker acceleration and faster time to plane — the number that actually matters most on short, sporty boats like these.
Do these boats require an oversize trailer permit to tow on US highways?
Both the Zodiac Cadet Solid 285 2011 and Zodiac Classic Mark I Solid 2013 share an 5 ft. 3 in. (1.6 m) beam — meaning both sit right at the 8’6" threshold that most US states use for standard-width loads. In most states you can tow at that width without a special permit, but regulations vary. Always check the rules for your state and any states you'll be passing through before your first long haul.
Are the Zodiac Cadet Solid 285 2011 and Zodiac Classic Mark I Solid 2013 from the same manufacturer?
Yes — both the Zodiac Cadet Solid 285 2011 and the Zodiac Classic Mark I Solid 2013 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.
