When two boats share the same hull type — in this case both the SeaArk DXS 1548 DKLD 2013 and the SeaArk Stealth 170 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?

On paper these two are close siblings in the size department — SeaArk DXS 1548 DKLD 2013 at 15,0 ft versus SeaArk Stealth 170 2013 at 17,2 ft. Weight tells a clearer story for trailering families: the SeaArk Stealth 170 2013 tips the scales at 143 lbs — 109 lbs less than the SeaArk DXS 1548 DKLD 2013 at 34 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 75 hp, the SeaArk Stealth 170 2013 has a 45-hp advantage over the SeaArk DXS 1548 DKLD 2013's 30-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 Stealth 170 2013 is rated for 5 passengers, while the SeaArk DXS 1548 DKLD 2013 caps at 4. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the SeaArk Stealth 170 2013 could be the deciding factor.

At this size, power-to-weight ratio matters more than outright horsepower. The SeaArk DXS 1548 DKLD 2013 comes in at 1 lbs per hp versus 2 lbs per hp for the SeaArk Stealth 170 2013. The lower the ratio the more explosive the acceleration — meaningful on a short RIB where bursts of speed, quick planing, and agility in surf or tight waterways define the experience.
