When two boats share the same hull type — in this case both the Key West 177 SK 2010 and the Key West 177 SK 2011 are modified vee designs with fiberglass 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 — Key West 177 SK 2010 at 17,3 ft versus Key West 177 SK 2011 at 17,3 ft. At 11 lbs and 11 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 — 90 hp for the Key West 177 SK 2010 and 90 hp for the Key West 177 SK 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. Both carry nearly identical fuel loads — 19 gal and 19 gal — so range won't be a tiebreaker here.

At this size, power-to-weight ratio matters more than outright horsepower. The Key West 177 SK 2011 comes in at 0 lbs per hp versus 0 lbs per hp for the Key West 177 SK 2010. 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.
