Alumacraft Tournament Sport 185 2005 vs Alumacraft Trophy 175 2011 — Same Brand, Different Boat

The Alumacraft Tournament Sport 185 2005 vs Alumacraft Trophy 175 2011 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 — Alumacraft Tournament Sport 185 2005 at 18,0 ft versus Alumacraft Trophy 175 2011 at 17,7 ft. Weight tells a clearer story for trailering families: the Alumacraft Trophy 175 2011 tips the scales at 155 lbs — 139 lbs less than the Alumacraft Tournament Sport 185 2005 at 16 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 200 hp, the Alumacraft Tournament Sport 185 2005 has a 50-hp advantage over the Alumacraft Trophy 175 2011's 150-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Both carry nearly identical fuel loads — 41 gal and 38 gal — so range won't be a tiebreaker here.

For family outings this is probably the sharpest distinction between the two. The Alumacraft Trophy 175 2011 is rated for 7 passengers, while the Alumacraft Tournament Sport 185 2005 caps at 6. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Alumacraft Trophy 175 2011 could be the deciding factor.

At this size, power-to-weight ratio matters more than outright horsepower. The Alumacraft Tournament Sport 185 2005 comes in at 0 lbs per hp versus 1 lbs per hp for the Alumacraft Trophy 175 2011. 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 Alumacraft Trophy 175 2011 if your priority is putting more people on the water — it handles 7 passengers and at 17,7 ft it has the deck room to back that rating up comfortably. The Alumacraft Tournament Sport 185 2005 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 6 that costs less to run day-to-day.

Alumacraft Tournament Sport 185 2005 vs Alumacraft Trophy 175 2011 — Common Questions

Which is the larger boat — the Alumacraft Tournament Sport 185 2005 or the Alumacraft Trophy 175 2011?
The Alumacraft Tournament Sport 185 2005 is the longer of the two at 18,0 feet overall. The Alumacraft Trophy 175 2011 comes in at 17,7 feet, making it roughly 0,3 ft shorter — a meaningful difference in deck room and overall on-water presence.
Which is easier to trailer — the Alumacraft Tournament Sport 185 2005 or the Alumacraft Trophy 175 2011?
For trailering, the Alumacraft Tournament Sport 185 2005 has the edge at 16 lbs dry weight versus 155 lbs for the Alumacraft Trophy 175 2011. 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.
Which boat can handle a bigger outboard?
The Alumacraft Tournament Sport 185 2005 is rated to a maximum of 200 hp, giving it the larger power ceiling. The Alumacraft Trophy 175 2011 tops out at 150 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.
How many people can each boat hold?
The Alumacraft Tournament Sport 185 2005 is Coast Guard rated for 6 passengers, while the Alumacraft Trophy 175 2011 is certified for 7. 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.
Which boat has the better power-to-weight ratio?
The Alumacraft Tournament Sport 185 2005 has a better power-to-weight ratio at 0 lbs per hp compared to 1 lbs per hp for the Alumacraft Trophy 175 2011. A lower number means quicker acceleration and faster time to plane — the number that actually matters most on short, sporty boats like these.
Which boat is wider, and does it affect trailering?
The Alumacraft Tournament Sport 185 2005 measures 96" wide, compared to 94" for the Alumacraft Trophy 175 2011. The US standard-width towing limit is 8’6" (102") in most states — anything over that may need a wide-load permit. Confirm your specific route requirements with each state's DOT.
Which boat has the larger fuel tank — the Alumacraft Tournament Sport 185 2005 or the Alumacraft Trophy 175 2011?
The Alumacraft Tournament Sport 185 2005 has the bigger tank at 41 gallons, versus 38 gallons on the Alumacraft Trophy 175 2011. That 3-gallon difference translates to roughly 9–15 nautical miles of additional range at cruising speed, depending on motor, load, and conditions.
Are the Alumacraft Tournament Sport 185 2005 and Alumacraft Trophy 175 2011 from the same manufacturer?
Yes — both the Alumacraft Tournament Sport 185 2005 and the Alumacraft Trophy 175 2011 are built by Alumacraft. 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.
