The Starcraft Marine C-Star 1600 OB 2005 vs Starcraft Marine C-Star 170 FS 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 C-Star 1600 OB 2005 at 15,0 ft versus Starcraft Marine C-Star 170 FS 2005 at 16,0 ft. Weight tells a clearer story for trailering families: the Starcraft Marine C-Star 170 FS 2005 tips the scales at 1 304 lbs — 1 162 lbs less than the Starcraft Marine C-Star 1600 OB 2005 at 142 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 125 hp, the Starcraft Marine C-Star 170 FS 2005 has a 35-hp advantage over the Starcraft Marine C-Star 1600 OB 2005's 90-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 C-Star 170 FS 2005 carries 32 gallons versus 23 gallons in the Starcraft Marine C-Star 1600 OB 2005. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.

Both boats are rated for 6 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.

At this size, power-to-weight ratio matters more than outright horsepower. The Starcraft Marine C-Star 1600 OB 2005 comes in at 2 lbs per hp versus 10 lbs per hp for the Starcraft Marine C-Star 170 FS 2005. 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.
