When two boats share the same hull type — in this case both the SunChaser 814 CR 2009 and the SunChaser Oasis 818 Cruise 2012 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 Oasis 818 Cruise 2012 measures 18,8 feet overall (2012), giving it roughly 4,8 additional feet of deck space compared to the SunChaser 814 CR 2009 at 14,0 feet (2009). Weight tells a clearer story for trailering families: the SunChaser 814 CR 2009 tips the scales at 1 025 lbs — 870 lbs more than the SunChaser Oasis 818 Cruise 2012 at 155 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 Oasis 818 Cruise 2012 tops out at 50 hp. Engine specs for the SunChaser 814 CR 2009 aren't listed — confirm with a dealer before selecting an outboard.
For family outings this is probably the sharpest distinction between the two. The SunChaser Oasis 818 Cruise 2012 is rated for 8 passengers, while the SunChaser 814 CR 2009 caps at 5. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the SunChaser Oasis 818 Cruise 2012 could be the deciding factor.
Bottom line: Choose the SunChaser Oasis 818 Cruise 2012 if your priority is putting more people on the water — it handles 8 passengers and at 18,8 ft it has the deck room to back that rating up comfortably. The SunChaser 814 CR 2009 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 5 that costs less to run day-to-day.
