Matching a deep vee Zodiac Medline IV 2010 against a modified vee Zodiac Yachtline 340 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 Medline IV 2010 measures 27,9 feet overall (2010), giving it roughly 16,8 additional feet of deck space compared to the Zodiac Yachtline 340 2013 at 11,2 feet (2013). Weight tells a clearer story for trailering families: the Zodiac Medline IV 2010 tips the scales at 3 527 lbs — 3 102 lbs more than the Zodiac Yachtline 340 2013 at 425 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 2010 has a 320-hp advantage over the Zodiac Yachtline 340 2013's 30-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 2010 is rated for 8 passengers, while the Zodiac Yachtline 340 2013 caps at 4. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Zodiac Medline IV 2010 could be the deciding factor.
At this size, power-to-weight ratio matters more than outright horsepower. The Zodiac Medline IV 2010 comes in at 10 lbs per hp versus 14 lbs per hp for the Zodiac Yachtline 340 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.
Top speed is rated at 57 mph for the Zodiac Medline IV 2010 and 30 mph for the Zodiac Yachtline 340 2013.
The Zodiac Yachtline 340 2013 is an inflatable design — lighter, easier to store, and quicker to launch from a beach or dock without a slipway. The Zodiac Medline IV 2010 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 Medline IV 2010 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 Yachtline 340 2013 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 4 that costs less to run day-to-day.
