The G3 Boats 1756 CCT DLX 2010 is a tunnel hull design and the G3 Boats 1756 SC 2009 is a modified-V design, so you're likely deciding between two noticeably 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 - G3 Boats 1756 CCT DLX 2010 at 17,1 ft versus G3 Boats 1756 SC 2009 at 16,0 ft. Weight tells a clearer story for trailering families: the G3 Boats 1756 CCT DLX 2010 tips the scales at 830 lbs - 130 lbs more than the G3 Boats 1756 SC 2009 at 700 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.
Both boats share a closely matched power ceiling - 70 hp for the G3 Boats 1756 CCT DLX 2010 and 70 hp for the G3 Boats 1756 SC 2009. Real-world performance will come down more to which motor is actually bolted on, its load at the time, and whether it's a 4-stroke or 2-stroke setup. Fuel capacity breaks the other way: the G3 Boats 1756 SC 2009 carries 21 gallons versus 12 gallons in the G3 Boats 1756 CCT DLX 2010. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.
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.
At this size, power-to-weight ratio matters more than outright horsepower. The G3 Boats 1756 SC 2009 comes in at 10 lbs per hp versus 12 lbs per hp for the G3 Boats 1756 CCT DLX 2010. 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.
Bottom line: The G3 Boats 1756 CCT DLX 2010 and G3 Boats 1756 SC 2009 are closely matched on the specs that matter most. Test-ride both on the water you actually use, check current dealer pricing, and factor in long-term service access before you sign.
