When two boats share the same hull type — in this case both the SunChaser 8520 4.0 2010 and the SunChaser 8520 CR 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?

On paper these two are close siblings in the size department — SunChaser 8520 4.0 2010 at 20,3 ft versus SunChaser 8520 CR 2010 at 20,3 ft. Weight tells a clearer story for trailering families: the SunChaser 8520 CR 2010 tips the scales at 1 875 lbs — 1 690 lbs less than the SunChaser 8520 4.0 2010 at 185 lbs. 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.

The SunChaser 8520 CR 2010 tops out at 115 hp. Engine specs for the SunChaser 8520 4.0 2010 aren't listed — confirm with a dealer before selecting an outboard.Both carry nearly identical fuel loads — 24 gal and 24 gal — so range won't be a tiebreaker here.

Both boats are rated for 12 passengers — a good fit for a family of four or five plus guests. Comfort at capacity is another matter; the longer hull typically means more seat options and better weight distribution.
