Starcraft Marine Islander 191 2005 vs Starcraft Marine Sport Runabout 172 OB Sport 2013 — Same Brand, Different Boat

The Starcraft Marine Islander 191 2005 vs Starcraft Marine Sport Runabout 172 OB Sport 2013 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 — Starcraft Marine Islander 191 2005 at 19,0 ft versus Starcraft Marine Sport Runabout 172 OB Sport 2013 at 16,8 ft. Weight tells a clearer story for trailering families: the Starcraft Marine Islander 191 2005 tips the scales at 1 525 lbs — 1 373 lbs more than the Starcraft Marine Sport Runabout 172 OB Sport 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.

The power gap is worth calling out. Rated to 130 hp, the Starcraft Marine Sport Runabout 172 OB Sport 2013 has a 127-hp advantage over the Starcraft Marine Islander 191 2005's 3-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Fuel capacity breaks the other way: the Starcraft Marine Islander 191 2005 carries 34 gallons versus 23 gallons in the Starcraft Marine Sport Runabout 172 OB Sport 2013. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.

Both boats are rated for 8 passengers — a good fit for a family of four or five plus guests. Comfort at capacity is another matter; the longer hull typically means more seat options and better weight distribution.

Bottom line: The Starcraft Marine Islander 191 2005 at 19,0 ft is the right call if deck space, comfort, and entertaining are top of your list. The Starcraft Marine Sport Runabout 172 OB Sport 2013 at 16,8 ft wins on trailering ease, likely lower purchase price, and simpler docking — a solid choice for a buyer who wants more boat for less money.

Starcraft Marine Islander 191 2005 vs Starcraft Marine Sport Runabout 172 OB Sport 2013 — Common Questions

Which is the larger boat — the Starcraft Marine Islander 191 2005 or the Starcraft Marine Sport Runabout 172 OB Sport 2013?
The Starcraft Marine Islander 191 2005 is the longer of the two at 19,0 feet overall. The Starcraft Marine Sport Runabout 172 OB Sport 2013 comes in at 16,8 feet, making it roughly 2,2 ft shorter — a meaningful difference in deck room and overall on-water presence.
Which is easier to trailer — the Starcraft Marine Islander 191 2005 or the Starcraft Marine Sport Runabout 172 OB Sport 2013?
For trailering, the Starcraft Marine Sport Runabout 172 OB Sport 2013 has the edge at 152 lbs dry weight versus 1 525 lbs for the Starcraft Marine Islander 191 2005. Add a motor (typically 300–500 lbs for an outboard in this class), gear, and a partial fuel load and the difference grows. Lighter is friendlier on smaller tow vehicles and on fuel economy while hauling.
Which boat can handle a bigger outboard?
The Starcraft Marine Sport Runabout 172 OB Sport 2013 is rated to a maximum of 130 hp, giving it the larger power ceiling. The Starcraft Marine Islander 191 2005 tops out at 3 hp. Keep in mind that maximum ratings are just that — matching the motor to the actual load and usage pattern usually matters more than chasing the ceiling.
How many people can each boat hold?
The Starcraft Marine Islander 191 2005 is Coast Guard rated for 8 passengers, while the Starcraft Marine Sport Runabout 172 OB Sport 2013 is certified for 8. Note that legal capacity and comfortable capacity aren't always the same thing — on a full day out, most experienced boaters aim for about 80% of the rated number to keep things comfortable.
Which boat is wider, and does it affect trailering?
The Starcraft Marine Islander 191 2005 measures 96" wide, compared to 9" for the Starcraft Marine Sport Runabout 172 OB Sport 2013. The US standard-width towing limit is 8’6" (102") in most states — anything over that may need a wide-load permit. Confirm your specific route requirements with each state's DOT.
Which boat has the larger fuel tank — the Starcraft Marine Islander 191 2005 or the Starcraft Marine Sport Runabout 172 OB Sport 2013?
The Starcraft Marine Islander 191 2005 has the bigger tank at 34 gallons, versus 23 gallons on the Starcraft Marine Sport Runabout 172 OB Sport 2013. That 11-gallon difference translates to roughly 33–55 nautical miles of additional range at cruising speed, depending on motor, load, and conditions.
Are the Starcraft Marine Islander 191 2005 and Starcraft Marine Sport Runabout 172 OB Sport 2013 from the same manufacturer?
Yes — both the Starcraft Marine Islander 191 2005 and the Starcraft Marine Sport Runabout 172 OB Sport 2013 are built by Starcraft Marine. That means shared dealer networks, common parts availability, and consistent build quality across the line. The choice between them is essentially a question of how much boat you need, not which brand you trust.
