SeaArk 1660 MVT Rescue 2011 vs SeaArk 1860MVJT 2007 — Same Brand, Different Boat

The SeaArk 1660 MVT Rescue 2011 vs SeaArk 1860MVJT 2007 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 1660 MVT Rescue 2011 at 16,0 ft versus SeaArk 1860MVJT 2007 at 18,0 ft. At 62 lbs and 5 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.

Both boats share a closely matched power ceiling — 50 hp for the SeaArk 1660 MVT Rescue 2011 and 65 hp for the SeaArk 1860MVJT 2007. 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 1860MVJT 2007 comes in at 0 lbs per hp versus 1 lbs per hp for the SeaArk 1660 MVT Rescue 2011. 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.

Bottom line: The SeaArk 1660 MVT Rescue 2011 and SeaArk 1860MVJT 2007 are closely matched on the specs that matter most. Test-ride both on the water you actually use, check current dealer pricing, and factor in long-term service access before you sign.

SeaArk 1660 MVT Rescue 2011 vs SeaArk 1860MVJT 2007 — Common Questions

Which is the larger boat — the SeaArk 1660 MVT Rescue 2011 or the SeaArk 1860MVJT 2007?
The SeaArk 1860MVJT 2007 is the longer of the two at 18,0 feet overall. The SeaArk 1660 MVT Rescue 2011 comes in at 16,0 feet, making it roughly 2,0 ft shorter — a meaningful difference in deck room and overall on-water presence.
Which is easier to trailer — the SeaArk 1660 MVT Rescue 2011 or the SeaArk 1860MVJT 2007?
For trailering, the SeaArk 1860MVJT 2007 has the edge at 5 lbs dry weight versus 62 lbs for the SeaArk 1660 MVT Rescue 2011. Add a motor (typically 300–500 lbs for an outboard in this class), gear, and a partial fuel load and the difference grows. Lighter is friendlier on smaller tow vehicles and on fuel economy while hauling.
Which boat can handle a bigger outboard?
The SeaArk 1860MVJT 2007 is rated to a maximum of 65 hp, giving it the larger power ceiling. The SeaArk 1660 MVT Rescue 2011 tops out at 50 hp. Keep in mind that maximum ratings are just that — matching the motor to the actual load and usage pattern usually matters more than chasing the ceiling.
How many people can each boat hold?
The SeaArk 1660 MVT Rescue 2011 is Coast Guard rated for 6 passengers, while the SeaArk 1860MVJT 2007 is certified for 6. Note that legal capacity and comfortable capacity aren't always the same thing — on a full day out, most experienced boaters aim for about 80% of the rated number to keep things comfortable.
Which boat has the better power-to-weight ratio?
The SeaArk 1860MVJT 2007 has a better power-to-weight ratio at 0 lbs per hp compared to 1 lbs per hp for the SeaArk 1660 MVT Rescue 2011. A lower number means quicker acceleration and faster time to plane — the number that actually matters most on short, sporty boats like these.
Do these boats require an oversize trailer permit to tow on US highways?
Both the SeaArk 1660 MVT Rescue 2011 and SeaArk 1860MVJT 2007 share an 82 in. (2.08 m) beam — meaning both sit right at the 8’6" threshold that most US states use for standard-width loads. In most states you can tow at that width without a special permit, but regulations vary. Always check the rules for your state and any states you'll be passing through before your first long haul.
Are the SeaArk 1660 MVT Rescue 2011 and SeaArk 1860MVJT 2007 from the same manufacturer?
Yes — both the SeaArk 1660 MVT Rescue 2011 and the SeaArk 1860MVJT 2007 are built by SeaArk. That means shared dealer networks, common parts availability, and consistent build quality across the line. The choice between them is essentially a question of how much boat you need, not which brand you trust.
