The SunChaser 818C 2008 vs SunChaser Fish 818 2013 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 — SunChaser 818C 2008 at 18,0 ft versus SunChaser Fish 818 2013 at 18,8 ft.

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 — 50 hp for the SunChaser 818C 2008 and 50 hp for the SunChaser Fish 818 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 SunChaser 818C 2008 is rated for 9 passengers, while the SunChaser Fish 818 2013 caps at 8. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the SunChaser 818C 2008 could be the deciding factor.
Bottom line: Choose the SunChaser 818C 2008 if your priority is putting more people on the water — it handles 9 passengers and at 18,0 ft it has the deck room to back that rating up comfortably. The SunChaser Fish 818 2013 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 8 that costs less to run day-to-day.
