Matching a modified vee Hydra-Sports 180CC 2010 against a deep vee Hydra-Sports 2100 CC 2011 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 Hydra-Sports 2100 CC 2011 measures 20,9 feet overall (2011), giving it roughly 3,4 additional feet of deck space compared to the Hydra-Sports 180CC 2010 at 17,5 feet (2010). Weight tells a clearer story for trailering families: the Hydra-Sports 2100 CC 2011 tips the scales at 3 493 lbs — 1 649 lbs less than the Hydra-Sports 180CC 2010 at 1 844 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 250 hp, the Hydra-Sports 2100 CC 2011 has a 100-hp advantage over the Hydra-Sports 180CC 2010's 150-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Fuel capacity breaks the other way: the Hydra-Sports 180CC 2010 carries 55 gallons versus 12 gallons in the Hydra-Sports 2100 CC 2011. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.
Both boats are rated for 6 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 Hydra-Sports 2100 CC 2011 at 20,9 ft is the right call if deck space, comfort, and entertaining are top of your list. The Hydra-Sports 180CC 2010 at 17,5 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.
