The Starcraft Marine 170 OB 2008 vs Starcraft Marine Islander 191 2006 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 170 OB 2008 at 17,0 ft versus Starcraft Marine Islander 191 2006 at 19,0 ft. Weight tells a clearer story for trailering families: the Starcraft Marine Islander 191 2006 tips the scales at 1 525 lbs — 252 lbs less than the Starcraft Marine 170 OB 2008 at 1 273 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 150 hp, the Starcraft Marine 170 OB 2008 has a 147-hp advantage over the Starcraft Marine Islander 191 2006's 3-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Both carry nearly identical fuel loads — 32 gal and 34 gal — so range won't be a tiebreaker here.

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.
