When two boats share the same hull type — in this case both the SunChaser 7520 Cruise 2013 and the SunChaser 8520 CR 2008 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?
Size is the most obvious dividing line here. The SunChaser 7520 Cruise 2013 measures 20,3 feet overall (2013), giving it roughly 18,3 additional feet of deck space compared to the SunChaser 8520 CR 2008 at 2,0 feet (2008). Weight tells a clearer story for trailering families: the SunChaser 8520 CR 2008 tips the scales at 1 875 lbs — 1 857 lbs less than the SunChaser 7520 Cruise 2013 at 18 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.
Both boats share a closely matched power ceiling — 90 hp for the SunChaser 7520 Cruise 2013 and 90 hp for the SunChaser 8520 CR 2008. 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. Both carry nearly identical fuel loads — 24 gal and 24 gal — so range won't be a tiebreaker here.
For family outings this is probably the sharpest distinction between the two. The SunChaser 8520 CR 2008 is rated for 12 passengers, while the SunChaser 7520 Cruise 2013 caps at 1. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the SunChaser 8520 CR 2008 could be the deciding factor.
Bottom line: Choose the SunChaser 8520 CR 2008 if your priority is putting more people on the water — it handles 12 passengers and at 2,0 ft it has the deck room to back that rating up comfortably. The SunChaser 7520 Cruise 2013 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 1 that costs less to run day-to-day.
