When two boats share the same hull type — in this case both the MirroCraft 1766 2013 and the MirroCraft 1877 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 1766 2013 at 17,3 ft versus MirroCraft 1877 2013 at 17,8 ft. At 145 lbs and 158 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.

The power gap is worth calling out. Rated to 175 hp, the MirroCraft 1877 2013 has a 25-hp advantage over the MirroCraft 1766 2013's 150-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Both carry nearly identical fuel loads — 29 gal and 29 gal — so range won't be a tiebreaker here.

For family outings this is probably the sharpest distinction between the two. The MirroCraft 1877 2013 is rated for 6 passengers, while the MirroCraft 1766 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 1877 2013 could be the deciding factor.

At this size, power-to-weight ratio matters more than outright horsepower. The MirroCraft 1877 2013 comes in at 1 lbs per hp versus 1 lbs per hp for the MirroCraft 1766 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.
