When two boats share the same hull type — in this case both the G3 Boats LX 20 F/C 2010 and the G3 Boats LX3 22 F/C Vinyl 2010 are pontoon 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?

The power gap is worth calling out. Rated to 225 hp, the G3 Boats LX3 22 F/C Vinyl 2010 has a 125-hp advantage over the G3 Boats LX 20 F/C 2010's 100-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Both carry nearly identical fuel loads — 3 gal and 3 gal — so range won't be a tiebreaker here.

For family outings this is probably the sharpest distinction between the two. The G3 Boats LX 20 F/C 2010 is rated for 11 passengers, while the G3 Boats LX3 22 F/C Vinyl 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 LX 20 F/C 2010 could be the deciding factor.

Both are 2-tube and 3-tube pontoon designs respectively. Tube diameter and gauge affect stability and load capacity — more so than most buyers realize when comparing on paper.
