When two boats share the same hull type — in this case both the Starcraft Marine 1800 IO Fish 2008 and the Starcraft Marine Limited 1700 OB 2010 are modified vee designs with fiberglass 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?
On paper these two are close siblings in the size department — Starcraft Marine 1800 IO Fish 2008 at 18,0 ft versus Starcraft Marine Limited 1700 OB 2010 at 16,8 ft. Weight tells a clearer story for trailering families: the Starcraft Marine 1800 IO Fish 2008 tips the scales at 1 725 lbs — 1 573 lbs more than the Starcraft Marine Limited 1700 OB 2010 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 Limited 1700 OB 2010 has a 126-hp advantage over the Starcraft Marine 1800 IO Fish 2008's 4-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 Limited 1700 OB 2010 carries 23 gallons versus 3 gallons in the Starcraft Marine 1800 IO Fish 2008. 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.
At this size, power-to-weight ratio matters more than outright horsepower. The Starcraft Marine Limited 1700 OB 2010 comes in at 1 lbs per hp versus 401 lbs per hp for the Starcraft Marine 1800 IO Fish 2008. 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: Performance buyers should lean toward the Starcraft Marine Limited 1700 OB 2010 and its 130-hp ceiling. If fuel economy and quieter running matter more than top-end speed, the Starcraft Marine 1800 IO Fish 2008 with its 4-hp rating is the more economical daily driver.
