Matching a inflatable non rigid Zodiac Cadet Solid 310 2012 against a inflatable rigid Zodiac Yachtline Deluxe 380 DL 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.
On paper these two are close siblings in the size department — Zodiac Cadet Solid 310 2012 at 10,2 ft versus Zodiac Yachtline Deluxe 380 DL 2008 at 12,0 ft. Weight tells a clearer story for trailering families: the Zodiac Yachtline Deluxe 380 DL 2008 tips the scales at 485 lbs — 392 lbs less than the Zodiac Cadet Solid 310 2012 at 93 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 40 hp, the Zodiac Yachtline Deluxe 380 DL 2008 has a 25-hp advantage over the Zodiac Cadet Solid 310 2012's 15-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.
At this size, power-to-weight ratio matters more than outright horsepower. The Zodiac Cadet Solid 310 2012 comes in at 6 lbs per hp versus 12 lbs per hp for the Zodiac Yachtline Deluxe 380 DL 2008. 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 33 mph for the Zodiac Yachtline Deluxe 380 DL 2008 and 22 mph for the Zodiac Cadet Solid 310 2012.
The Zodiac Cadet Solid 310 2012 is an inflatable design — lighter, easier to store, and quicker to launch from a beach or dock without a slipway. The Zodiac Yachtline Deluxe 380 DL 2008 is a rigid hull, which typically offers a more confident ride in chop and easier maintenance over the long term.
Bottom line: Performance buyers should lean toward the Zodiac Yachtline Deluxe 380 DL 2008 and its 40-hp ceiling. If fuel economy and quieter running matter more than top-end speed, the Zodiac Cadet Solid 310 2012 with its 15-hp rating is the more economical daily driver.
