The Zodiac Medline IV 2010 vs Zodiac Zoom 380 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 IV 2010 measures 27,9 feet overall (2010), giving it roughly 15,9 additional feet of deck space compared to the Zodiac Zoom 380 S 2007 at 12,0 feet (2007). Weight tells a clearer story for trailering families: the Zodiac Medline IV 2010 tips the scales at 3 527 lbs — 3 406 lbs more than the Zodiac Zoom 380 S 2007 at 121 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 335-hp advantage over the Zodiac Zoom 380 S 2007's 15-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 Zoom 380 S 2007 caps at 6. 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.
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 Zoom 380 S 2007 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 6 that costs less to run day-to-day.
