Matching a deep vee Zodiac Pro Classic 650 2013 against a inflatable non rigid Zodiac Zoom SP 400 ALU 2013 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 Pro Classic 650 2013 measures 20,7 feet overall (2013), giving it roughly 7,6 additional feet of deck space compared to the Zodiac Zoom SP 400 ALU 2013 at 13,1 feet (2013). Weight tells a clearer story for trailering families: the Zodiac Pro Classic 650 2013 tips the scales at 1 257 lbs — 1 070 lbs more than the Zodiac Zoom SP 400 ALU 2013 at 187 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 150 hp, the Zodiac Pro Classic 650 2013 has a 125-hp advantage over the Zodiac Zoom SP 400 ALU 2013's 25-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 Zoom SP 400 ALU 2013 is rated for 7 passengers, while the Zodiac Pro Classic 650 2013 caps at 5. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Zodiac Zoom SP 400 ALU 2013 could be the deciding factor.
At this size, power-to-weight ratio matters more than outright horsepower. The Zodiac Zoom SP 400 ALU 2013 comes in at 8 lbs per hp versus 8 lbs per hp for the Zodiac Pro Classic 650 2013. 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.
The Zodiac Pro Classic 650 2013 has a documented top speed of 85 mph. Speed data wasn't available for the other model.
The Zodiac Pro Classic 650 2013 is an inflatable design — lighter, easier to store, and quicker to launch from a beach or dock without a slipway. The Zodiac Zoom SP 400 ALU 2013 is a rigid hull, which typically offers a more confident ride in chop and easier maintenance over the long term.
Bottom line: Choose the Zodiac Zoom SP 400 ALU 2013 if your priority is putting more people on the water — it handles 7 passengers and at 13,1 ft it has the deck room to back that rating up comfortably. The Zodiac Pro Classic 650 2013 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 5 that costs less to run day-to-day.
