When two boats share the same hull type — in this case both the MirroCraft 1676 2013 and the MirroCraft 1686 2013 are deep vee 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 — MirroCraft 1676 2013 at 16,2 ft versus MirroCraft 1686 2013 at 16,8 ft. Weight tells a clearer story for trailering families: the MirroCraft 1676 2013 tips the scales at 655 lbs — 646 lbs more than the MirroCraft 1686 2013 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 — 60 hp for the MirroCraft 1676 2013 and 60 hp for the MirroCraft 1686 2013. 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 2013 is rated for 6 passengers, while the MirroCraft 1676 2013 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 2013 could be the deciding factor.

At this size, power-to-weight ratio matters more than outright horsepower. The MirroCraft 1686 2013 comes in at 0 lbs per hp versus 11 lbs per hp for the MirroCraft 1676 2013. 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.
