When two boats share the same hull type — in this case both the SeaArk 1652DKLD 2010 and the SeaArk CRX 186 2011 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 1652DKLD 2010 at 16,0 ft versus SeaArk CRX 186 2011 at 18,5 ft. At 35 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 power gap is worth calling out. Rated to 140 hp, the SeaArk CRX 186 2011 has a 95-hp advantage over the SeaArk 1652DKLD 2010's 45-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load.
Both boats are rated for 5 passengers — a good fit for a family of four or five plus guests. Comfort at capacity is another matter; the longer hull typically means more seat options and better weight distribution.
Bottom line: The SeaArk CRX 186 2011 at 18,5 ft is the right call if deck space, comfort, and entertaining are top of your list. The SeaArk 1652DKLD 2010 at 16,0 ft wins on trailering ease, likely lower purchase price, and simpler docking — a solid choice for a buyer who wants more boat for less money.
