The Parker Boats 1801 Center Console 2007 vs Parker Boats 2120 Sport Cabin 2009 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 — Parker Boats 1801 Center Console 2007 at 18,0 ft versus Parker Boats 2120 Sport Cabin 2009 at 21,0 ft.
