When two boats share the same hull type — in this case both the G3 Boats 1648 WL Jon 2013 and the G3 Boats 2072 CC 2013 are flat designs with aluminum construction — the buying decision usually comes down to a handful of practical questions: how many people are you putting on the water, how far do you trailer, and what does your tow vehicle weigh?
Size is the most obvious dividing line here. The G3 Boats 2072 CC 2013 measures 19,8 feet overall (2013), giving it roughly 4,0 additional feet of deck space compared to the G3 Boats 1648 WL Jon 2013 at 15,8 feet (2013). At 38 lbs and 14 lbs respectively, both sit in a similar weight class — either should pair comfortably with most mid-size SUVs and half-ton trucks, though always confirm your specific tow rating with the motor added.
The power gap is worth calling out. Rated to 115 hp, the G3 Boats 2072 CC 2013 has a 90-hp advantage over the G3 Boats 1648 WL Jon 2013's 25-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load.
For family outings this is probably the sharpest distinction between the two. The G3 Boats 2072 CC 2013 is rated for 8 passengers, while the G3 Boats 1648 WL Jon 2013 caps at 4. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the G3 Boats 2072 CC 2013 could be the deciding factor.
Bottom line: Choose the G3 Boats 2072 CC 2013 if your priority is putting more people on the water — it handles 8 passengers and at 19,8 ft it has the deck room to back that rating up comfortably. The G3 Boats 1648 WL Jon 2013 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 4 that costs less to run day-to-day.
