The G3 Boats 1236 2005 vs G3 Boats 1436 LW 2011 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.
On paper these two are close siblings in the size department — G3 Boats 1236 2005 at 12,0 ft versus G3 Boats 1436 LW 2011 at 13,9 ft.
