When two boats share the same hull type — in this case both the SeaArk 1652MVT 2010 and the SeaArk Tunnel Jon 1660MVT 2008 are tunnel 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 1652MVT 2010 at 16,0 ft versus SeaArk Tunnel Jon 1660MVT 2008 at 16,0 ft. Weight tells a clearer story for trailering families: the SeaArk Tunnel Jon 1660MVT 2008 tips the scales at 475 lbs — 130 lbs less than the SeaArk 1652MVT 2010 at 345 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.

Both boats share a closely matched power ceiling — 45 hp for the SeaArk 1652MVT 2010 and 50 hp for the SeaArk Tunnel Jon 1660MVT 2008. Real-world performance will come down more to which motor is actually bolted on, its load at the time, and whether it's a 4-stroke or 2-stroke setup.

Both boats are rated for 6 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 1652MVT 2010 comes in at 8 lbs per hp versus 10 lbs per hp for the SeaArk Tunnel Jon 1660MVT 2008. 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.
