When two boats share the same hull type — in this case both the G3 Boats 1436 2011 and the G3 Boats 1648 LW Jon 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?

On paper these two are close siblings in the size department — G3 Boats 1436 2011 at 13,9 ft versus G3 Boats 1648 LW Jon 2013 at 15,8 ft. Weight tells a clearer story for trailering families: the G3 Boats 1436 2011 tips the scales at 152 lbs — 125 lbs more than the G3 Boats 1648 LW Jon 2013 at 27 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 — 15 hp for the G3 Boats 1436 2011 and 25 hp for the G3 Boats 1648 LW Jon 2013. 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 1648 LW Jon 2013 is rated for 4 passengers, while the G3 Boats 1436 2011 caps at 3. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the G3 Boats 1648 LW Jon 2013 could be the deciding factor.

At this size, power-to-weight ratio matters more than outright horsepower. The G3 Boats 1648 LW Jon 2013 comes in at 1 lbs per hp versus 10 lbs per hp for the G3 Boats 1436 2011. 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.
