When two boats share the same hull type — in this case both the SunChaser 818 Cruise 2011 and the SunChaser DS20 Cruise 2011 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 818 Cruise 2011 at 18,3 ft versus SunChaser DS20 Cruise 2011 at 20,3 ft. Weight tells a clearer story for trailering families: the SunChaser 818 Cruise 2011 tips the scales at 1 425 lbs — 1 240 lbs more than the SunChaser DS20 Cruise 2011 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 power gap is worth calling out. Rated to 115 hp, the SunChaser DS20 Cruise 2011 has a 65-hp advantage over the SunChaser 818 Cruise 2011's 50-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load.
For family outings this is probably the sharpest distinction between the two. The SunChaser DS20 Cruise 2011 is rated for 11 passengers, while the SunChaser 818 Cruise 2011 caps at 9. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the SunChaser DS20 Cruise 2011 could be the deciding factor.
Bottom line: Choose the SunChaser DS20 Cruise 2011 if your priority is putting more people on the water — it handles 11 passengers and at 20,3 ft it has the deck room to back that rating up comfortably. The SunChaser 818 Cruise 2011 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 9 that costs less to run day-to-day.
