The Alumacraft Competitor 165 Sport 2013 vs Alumacraft Tournament Pro 175 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 — Alumacraft Competitor 165 Sport 2013 at 16,6 ft versus Alumacraft Tournament Pro 175 2005 at 17,0 ft. Weight tells a clearer story for trailering families: the Alumacraft Tournament Pro 175 2005 tips the scales at 1 385 lbs — 1 281 lbs less than the Alumacraft Competitor 165 Sport 2013 at 104 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.
Both boats share a closely matched power ceiling — 90 hp for the Alumacraft Competitor 165 Sport 2013 and 90 hp for the Alumacraft Tournament Pro 175 2005. Real-world performance will come down more to which motor is actually bolted on, its load at the time, and whether it's a 4-stroke or 2-stroke setup. Fuel capacity breaks the other way: the Alumacraft Tournament Pro 175 2005 carries 34 gallons versus 17 gallons in the Alumacraft Competitor 165 Sport 2013. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.
For family outings this is probably the sharpest distinction between the two. The Alumacraft Competitor 165 Sport 2013 is rated for 6 passengers, while the Alumacraft Tournament Pro 175 2005 caps at 5. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Alumacraft Competitor 165 Sport 2013 could be the deciding factor.
At this size, power-to-weight ratio matters more than outright horsepower. The Alumacraft Competitor 165 Sport 2013 comes in at 1 lbs per hp versus 15 lbs per hp for the Alumacraft Tournament Pro 175 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.
Bottom line: Choose the Alumacraft Competitor 165 Sport 2013 if your priority is putting more people on the water — it handles 6 passengers and at 16,6 ft it has the deck room to back that rating up comfortably. The Alumacraft Tournament Pro 175 2005 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 5 that costs less to run day-to-day.
