When two boats share the same hull type — in this case both the Starcraft Marine 166 DC 2008 and the Starcraft Marine Sport Runabout 172 OB Ski Fish 2013 are modified 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 — Starcraft Marine 166 DC 2008 at 16,0 ft versus Starcraft Marine Sport Runabout 172 OB Ski Fish 2013 at 16,8 ft. Weight tells a clearer story for trailering families: the Starcraft Marine 166 DC 2008 tips the scales at 1 047 lbs — 895 lbs more than the Starcraft Marine Sport Runabout 172 OB Ski Fish 2013 at 152 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 — 125 hp for the Starcraft Marine 166 DC 2008 and 130 hp for the Starcraft Marine Sport Runabout 172 OB Ski Fish 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. Fuel capacity breaks the other way: the Starcraft Marine 166 DC 2008 carries 32 gallons versus 23 gallons in the Starcraft Marine Sport Runabout 172 OB Ski Fish 2013. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.

For family outings this is probably the sharpest distinction between the two. The Starcraft Marine Sport Runabout 172 OB Ski Fish 2013 is rated for 8 passengers, while the Starcraft Marine 166 DC 2008 caps at 6. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Starcraft Marine Sport Runabout 172 OB Ski Fish 2013 could be the deciding factor.

At this size, power-to-weight ratio matters more than outright horsepower. The Starcraft Marine Sport Runabout 172 OB Ski Fish 2013 comes in at 1 lbs per hp versus 8 lbs per hp for the Starcraft Marine 166 DC 2008. 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.
