When two boats share the same hull type — in this case both the Starcraft Marine Alaskan 13 DLX 2013 and the Starcraft Marine Sport Runabout 172 OB Sport 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?

Size is the most obvious dividing line here. The Starcraft Marine Sport Runabout 172 OB Sport 2013 measures 16,8 feet overall (2013), giving it roughly 3,9 additional feet of deck space compared to the Starcraft Marine Alaskan 13 DLX 2013 at 12,9 feet (2013). At 225 lbs and 152 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 130 hp, the Starcraft Marine Sport Runabout 172 OB Sport 2013 has a 105-hp advantage over the Starcraft Marine Alaskan 13 DLX 2013's 25-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load.

For family outings this is probably the sharpest distinction between the two. The Starcraft Marine Sport Runabout 172 OB Sport 2013 is rated for 8 passengers, while the Starcraft Marine Alaskan 13 DLX 2013 caps at 3. 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 Sport 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 Sport 2013 comes in at 1 lbs per hp versus 9 lbs per hp for the Starcraft Marine Alaskan 13 DLX 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.
