Matching a modified vee MirroCraft 1677-O 2012 against a deep vee MirroCraft 1686 2011 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 — MirroCraft 1677-O 2012 at 16,2 ft versus MirroCraft 1686 2011 at 16,8 ft. Weight tells a clearer story for trailering families: the MirroCraft 1677-O 2012 tips the scales at 705 lbs — 696 lbs more than the MirroCraft 1686 2011 at 9 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 — 75 hp for the MirroCraft 1677-O 2012 and 60 hp for the MirroCraft 1686 2011. 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.
For family outings this is probably the sharpest distinction between the two. The MirroCraft 1686 2011 is rated for 6 passengers, while the MirroCraft 1677-O 2012 caps at 5. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the MirroCraft 1686 2011 could be the deciding factor.
At this size, power-to-weight ratio matters more than outright horsepower. The MirroCraft 1686 2011 comes in at 0 lbs per hp versus 9 lbs per hp for the MirroCraft 1677-O 2012. 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: Choose the MirroCraft 1686 2011 if your priority is putting more people on the water — it handles 6 passengers and at 16,8 ft it has the deck room to back that rating up comfortably. The MirroCraft 1677-O 2012 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 5 that costs less to run day-to-day.
