The Starcraft Marine Bay 170 2013 vs Starcraft Marine C-Star 1700 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.
On paper these two are close siblings in the size department — Starcraft Marine Bay 170 2013 at 16,5 ft versus Starcraft Marine C-Star 1700 OB 2005 at 16,0 ft. Weight tells a clearer story for trailering families: the Starcraft Marine Bay 170 2013 tips the scales at 1 061 lbs — 909 lbs more than the Starcraft Marine C-Star 1700 OB 2005 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 — 115 hp for the Starcraft Marine Bay 170 2013 and 130 hp for the Starcraft Marine C-Star 1700 OB 2005. 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 C-Star 1700 OB 2005 carries 23 gallons versus 19 gallons in the Starcraft Marine Bay 170 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 C-Star 1700 OB 2005 is rated for 8 passengers, while the Starcraft Marine Bay 170 2013 caps at 5. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Starcraft Marine C-Star 1700 OB 2005 could be the deciding factor.
At this size, power-to-weight ratio matters more than outright horsepower. The Starcraft Marine C-Star 1700 OB 2005 comes in at 1 lbs per hp versus 9 lbs per hp for the Starcraft Marine Bay 170 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.
Bottom line: Choose the Starcraft Marine C-Star 1700 OB 2005 if your priority is putting more people on the water — it handles 8 passengers and at 16,0 ft it has the deck room to back that rating up comfortably. The Starcraft Marine Bay 170 2013 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 5 that costs less to run day-to-day.
