The McKee Craft Bay Classic 185 2007 vs McKee Craft Marathon 172 CC 2007 comparison sits squarely in the category of decisions where specs alone won't tell the whole story: intended use, storage, and long-term ownership costs all factor in.
On paper these two are close siblings in the size department - McKee Craft Bay Classic 185 2007 at 18,0 ft versus McKee Craft Marathon 172 CC 2007 at 17,0 ft.

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 - 70 hp for the McKee Craft Bay Classic 185 2007 and 60 hp for the McKee Craft Marathon 172 CC 2007. 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 - 35 gal and 36 gal - so range won't be a tiebreaker here.

The McKee Craft Marathon 172 CC 2007 comes in at 21 lbs per hp versus 22 lbs per hp for the McKee Craft Bay Classic 185 2007. 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.
