The G3 Boats 1860 CC 2010 vs G3 Boats PB 20F 2005 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 G3 Boats 1860 CC 2010 measures 17,1 feet overall (2010), giving it roughly 15,1 additional feet of deck space compared to the G3 Boats PB 20F 2005 at 2,0 feet (2005). Weight tells a clearer story for trailering families: the G3 Boats 1860 CC 2010 tips the scales at 885 lbs — 870 lbs more than the G3 Boats PB 20F 2005 at 15 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 — 90 hp for the G3 Boats 1860 CC 2010 and 100 hp for the G3 Boats PB 20F 2005. 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 PB 20F 2005 carries 23 gallons versus 2 gallons in the G3 Boats 1860 CC 2010. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.

For family outings this is probably the sharpest distinction between the two. The G3 Boats PB 20F 2005 is rated for 11 passengers, while the G3 Boats 1860 CC 2010 caps at 6. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the G3 Boats PB 20F 2005 could be the deciding factor.

At this size, power-to-weight ratio matters more than outright horsepower. The G3 Boats PB 20F 2005 comes in at 0 lbs per hp versus 10 lbs per hp for the G3 Boats 1860 CC 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.
