When two boats share the same hull type — in this case both the SeaArk CRX 186 2012 and the SeaArk DuckHawk 2072SS 2013 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?
Size is the most obvious dividing line here. The SeaArk CRX 186 2012 measures 18,5 feet overall (2012), giving it roughly 16,5 additional feet of deck space compared to the SeaArk DuckHawk 2072SS 2013 at 2,0 feet (2013). At 11 lbs and 81 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 power gap is worth calling out. Rated to 140 hp, the SeaArk CRX 186 2012 has a 50-hp advantage over the SeaArk DuckHawk 2072SS 2013's 90-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 SeaArk DuckHawk 2072SS 2013 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 DuckHawk 2072SS 2013 could be the deciding factor.
Bottom line: Choose the SeaArk DuckHawk 2072SS 2013 if your priority is putting more people on the water — it handles 6 passengers and at 2,0 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.
