The Starcraft Marine C-Star 1800 I/O 2005 vs Starcraft Marine Limited 2018 I/O 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 - Starcraft Marine C-Star 1800 I/O 2005 at 18,0 ft versus Starcraft Marine Limited 2018 I/O 2011 at 20,2 ft.
