Matching a pontoon G3 Boats 188 C 2010 against a modified vee G3 Boats Guide V18 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.
On paper these two are close siblings in the size department — G3 Boats 188 C 2010 at 18,0 ft versus G3 Boats Guide V18 2011 at 17,8 ft. Weight tells a clearer story for trailering families: the G3 Boats 188 C 2010 tips the scales at 162 lbs — 108 lbs more than the G3 Boats Guide V18 2011 at 54 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 — 75 hp for the G3 Boats 188 C 2010 and 70 hp for the G3 Boats Guide V18 2011. 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.
For family outings this is probably the sharpest distinction between the two. The G3 Boats 188 C 2010 is rated for 8 passengers, while the G3 Boats Guide V18 2011 caps at 7. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the G3 Boats 188 C 2010 could be the deciding factor.
At this size, power-to-weight ratio matters more than outright horsepower. The G3 Boats Guide V18 2011 comes in at 1 lbs per hp versus 2 lbs per hp for the G3 Boats 188 C 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.

The G3 Boats Guide V18 2011 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 7 that costs less to run day-to-day.
