Starcraft Marine Islander 191 2004 vs Starcraft Marine Pro-Star 1800 2004 - Boat Spec Comparison

Q: Which is easier to trailer — the Starcraft Marine Islander 191 2004 or the Starcraft Marine Pro-Star 1800 2004?

For trailering, the Starcraft Marine Islander 191 2004 has the edge at 1 525 lbs dry weight versus 1 763 lbs for the Starcraft Marine Pro-Star 1800 2004. Add a motor (typically 300–500 lbs for an outboard in this class), gear, and a partial fuel load and the difference grows. Lighter is friendlier on smaller tow vehicles and on fuel economy while hauling.

Q: Which boat can handle a bigger outboard?

The Starcraft Marine Pro-Star 1800 2004 is rated to a maximum of 175 hp, giving it the larger power ceiling. The Starcraft Marine Islander 191 2004 tops out at 135 hp. Keep in mind that maximum ratings are just that — matching the motor to the actual load and usage pattern usually matters more than chasing the ceiling.

Q: How many people can each boat hold?

The Starcraft Marine Islander 191 2004 is Coast Guard rated for 8 passengers, while the Starcraft Marine Pro-Star 1800 2004 is certified for 6. Note that legal capacity and comfortable capacity aren't always the same thing — on a full day out, most experienced boaters aim for about 80% of the rated number to keep things comfortable.

Q: Do these boats require an oversize trailer permit to tow on US highways?

Both the Starcraft Marine Islander 191 2004 and Starcraft Marine Pro-Star 1800 2004 share an 96 in beam — meaning both sit right at the 8’6" threshold that most US states use for standard-width loads. In most states you can tow at that width without a special permit, but regulations vary. Always check the rules for your state and any states you'll be passing through before your first long haul.

Q: Which boat has the larger fuel tank — the Starcraft Marine Islander 191 2004 or the Starcraft Marine Pro-Star 1800 2004?

The Starcraft Marine Pro-Star 1800 2004 has the bigger tank at 37 gallons, versus 34 gallons on the Starcraft Marine Islander 191 2004. That 3-gallon difference translates to roughly 9–15 nautical miles of additional range at cruising speed, depending on motor, load, and conditions.

Q: Are the Starcraft Marine Islander 191 2004 and Starcraft Marine Pro-Star 1800 2004 from the same manufacturer?

Yes — both the Starcraft Marine Islander 191 2004 and the Starcraft Marine Pro-Star 1800 2004 are built by Starcraft Marine. That means shared dealer networks, common parts availability, and consistent build quality across the line. The choice between them is essentially a question of how much boat you need, not which brand you trust.

Detailed Evaluation & Buyer Recommendation

Starcraft Marine Islander 191 2004 vs Starcraft Marine Pro-Star 1800 2004 — Same Brand, Different Boat

The Starcraft Marine Islander 191 2004 vs Starcraft Marine Pro-Star 1800 2004 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.

The power gap is worth calling out. Rated to 175 hp, the Starcraft Marine Pro-Star 1800 2004 has a 40-hp advantage over the Starcraft Marine Islander 191 2004's 135-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Both carry nearly identical fuel loads — 34 gal and 37 gal — so range won't be a tiebreaker here.

For family outings this is probably the sharpest distinction between the two. The Starcraft Marine Islander 191 2004 is rated for 8 passengers, while the Starcraft Marine Pro-Star 1800 2004 caps at 6. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Starcraft Marine Islander 191 2004 could be the deciding factor.

Bottom line: Choose the Starcraft Marine Islander 191 2004 if your priority is putting more people on the water — it handles 8 passengers and at 0,0 ft it has the deck room to back that rating up comfortably. The Starcraft Marine Pro-Star 1800 2004 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 6 that costs less to run day-to-day.
