The SeaArk 1652 SLD 2005 vs SeaArk 1860 Tunnel Pro (CC) 2013 comparison sits squarely in the category of decisions where specs alone won't tell the whole story — intended use, storage, and long-term ownership costs all factor in.

On paper these two are close siblings in the size department — SeaArk 1652 SLD 2005 at 16,0 ft versus SeaArk 1860 Tunnel Pro (CC) 2013 at 18,0 ft. Weight tells a clearer story for trailering families: the SeaArk 1652 SLD 2005 tips the scales at 425 lbs — 372 lbs more than the SeaArk 1860 Tunnel Pro (CC) 2013 at 53 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 80 hp, the SeaArk 1860 Tunnel Pro (CC) 2013 has a 35-hp advantage over the SeaArk 1652 SLD 2005'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.

At this size, power-to-weight ratio matters more than outright horsepower. The SeaArk 1860 Tunnel Pro (CC) 2013 comes in at 1 lbs per hp versus 9 lbs per hp for the SeaArk 1652 SLD 2005. 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.
