Matching a deep vee Zodiac Medline II 2010 against a inflatable rigid Zodiac Pro Open 650 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 Medline II 2010 at 19,7 ft versus Zodiac Pro Open 650 2008 at 21,0 ft. Weight tells a clearer story for trailering families: the Zodiac Medline II 2010 tips the scales at 1 521 lbs — 133 lbs more than the Zodiac Pro Open 650 2008 at 1 388 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 175 hp, the Zodiac Pro Open 650 2008 has a 25-hp advantage over the Zodiac Medline II 2010's 150-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.
