The Zodiac Medline II 2010 vs Zodiac Zoom 340 S 2007 comparison sits squarely in the category of decisions where specs alone won't tell the whole story — intended use, storage, and long-term ownership costs all factor in.
Size is the most obvious dividing line here. The Zodiac Medline II 2010 measures 19,7 feet overall (2010), giving it roughly 8,7 additional feet of deck space compared to the Zodiac Zoom 340 S 2007 at 11,0 feet (2007). Weight tells a clearer story for trailering families: the Zodiac Medline II 2010 tips the scales at 1 521 lbs — 1 413 lbs more than the Zodiac Zoom 340 S 2007 at 108 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 Medline II 2010 has a 140-hp advantage over the Zodiac Zoom 340 S 2007's 10-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 Medline II 2010 at 19,7 ft is the right call if deck space, comfort, and entertaining are top of your list. The Zodiac Zoom 340 S 2007 at 11,0 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.
