SeaArk CRX 186 2012 vs SeaArk Jet Tunnel 1652MVJT 2008 — Same Brand, Different Boat

Matching a modified vee SeaArk CRX 186 2012 against a tunnel SeaArk Jet Tunnel 1652MVJT 2008 means you're likely deciding between two genuinely different on-water experiences. Hull type shapes everything from ride quality and fuel burn to dock handling and resale trajectory.

On paper these two are close siblings in the size department — SeaArk CRX 186 2012 at 18,5 ft versus SeaArk Jet Tunnel 1652MVJT 2008 at 16,0 ft. Weight tells a clearer story for trailering families: the SeaArk Jet Tunnel 1652MVJT 2008 tips the scales at 345 lbs — 334 lbs less than the SeaArk CRX 186 2012 at 11 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 140 hp, the SeaArk CRX 186 2012 has a 95-hp advantage over the SeaArk Jet Tunnel 1652MVJT 2008'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 2012 at 18,5 ft is the right call if deck space, comfort, and entertaining are top of your list. The SeaArk Jet Tunnel 1652MVJT 2008 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.

SeaArk CRX 186 2012 vs SeaArk Jet Tunnel 1652MVJT 2008 — Common Questions

Which is the larger boat — the SeaArk CRX 186 2012 or the SeaArk Jet Tunnel 1652MVJT 2008?
The SeaArk CRX 186 2012 is the longer of the two at 18,5 feet overall. The SeaArk Jet Tunnel 1652MVJT 2008 comes in at 16,0 feet, making it roughly 2,5 ft shorter — a meaningful difference in deck room and overall on-water presence.
Which is easier to trailer — the SeaArk CRX 186 2012 or the SeaArk Jet Tunnel 1652MVJT 2008?
For trailering, the SeaArk CRX 186 2012 has the edge at 11 lbs dry weight versus 345 lbs for the SeaArk Jet Tunnel 1652MVJT 2008. 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 CRX 186 2012 is rated to a maximum of 140 hp, giving it the larger power ceiling. The SeaArk Jet Tunnel 1652MVJT 2008 tops out at 45 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 CRX 186 2012 is Coast Guard rated for 5 passengers, while the SeaArk Jet Tunnel 1652MVJT 2008 is certified for 5. 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 is wider, and does it affect trailering?
The SeaArk CRX 186 2012 measures 83" wide, compared to 72" for the SeaArk Jet Tunnel 1652MVJT 2008. The US standard-width towing limit is 8’6" (102") in most states — anything over that may need a wide-load permit. Confirm your specific route requirements with each state's DOT.
Are the SeaArk CRX 186 2012 and SeaArk Jet Tunnel 1652MVJT 2008 from the same manufacturer?
Yes — both the SeaArk CRX 186 2012 and the SeaArk Jet Tunnel 1652MVJT 2008 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.
