When two boats share the same hull type — in this case both the SeaArk C.U.B. Models 2011 and the SeaArk CRX 186 2012 are modified vee 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 — SeaArk C.U.B. Models 2011 at 20,1 ft versus SeaArk CRX 186 2012 at 18,5 ft. At 87 lbs and 11 lbs respectively, both sit in a similar weight class — either should pair comfortably with most mid-size SUVs and half-ton trucks, though always confirm your specific tow rating with the motor added.
The SeaArk CRX 186 2012 tops out at 140 hp. Engine specs for the SeaArk C.U.B. Models 2011 aren't listed — confirm with a dealer before selecting an outboard.
For family outings this is probably the sharpest distinction between the two. The SeaArk C.U.B. Models 2011 is rated for 6 passengers, while the SeaArk CRX 186 2012 caps at 5. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the SeaArk C.U.B. Models 2011 could be the deciding factor.
Bottom line: Choose the SeaArk C.U.B. Models 2011 if your priority is putting more people on the water — it handles 6 passengers and at 20,1 ft it has the deck room to back that rating up comfortably. The SeaArk CRX 186 2012 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 5 that costs less to run day-to-day.
