The Starcraft Marine 170 2009 vs Starcraft Marine Aurora 2210 OB 2005 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.
Size is the most obvious dividing line here. The Starcraft Marine Aurora 2210 OB 2005 measures 21,0 feet overall (2005), giving it roughly 4,0 additional feet of deck space compared to the Starcraft Marine 170 2009 at 17,0 feet (2009). Weight tells a clearer story for trailering families: the Starcraft Marine 170 2009 tips the scales at 1 273 lbs — 989 lbs more than the Starcraft Marine Aurora 2210 OB 2005 at 284 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 250 hp, the Starcraft Marine Aurora 2210 OB 2005 has a 100-hp advantage over the Starcraft Marine 170 2009's 150-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 Aurora 2210 OB 2005 carries 51 gallons versus 32 gallons in the Starcraft Marine 170 2009. 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 Aurora 2210 OB 2005 is rated for 12 passengers, while the Starcraft Marine 170 2009 caps at 8. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Starcraft Marine Aurora 2210 OB 2005 could be the deciding factor.
Bottom line: Choose the Starcraft Marine Aurora 2210 OB 2005 if your priority is putting more people on the water — it handles 12 passengers and at 21,0 ft it has the deck room to back that rating up comfortably. The Starcraft Marine 170 2009 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 8 that costs less to run day-to-day.
