Matching a deep vee Alumacraft Competitor 165 CS 2012 against a modified vee Alumacraft Trophy 185 2007 means you're likely deciding between two genuinely different on-water experiences. Hull type shapes everything from ride quality and fuel burn to dock handling and resale trajectory.
On paper these two are close siblings in the size department — Alumacraft Competitor 165 CS 2012 at 16,6 ft versus Alumacraft Trophy 185 2007 at 18,0 ft. At 104 lbs and 178 lbs respectively, both sit in a similar weight class — either should pair comfortably with most mid-size SUVs and half-ton trucks, though always confirm your specific tow rating with the motor added.
The power gap is worth calling out. Rated to 175 hp, the Alumacraft Trophy 185 2007 has a 85-hp advantage over the Alumacraft Competitor 165 CS 2012's 90-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Fuel capacity breaks the other way: the Alumacraft Competitor 165 CS 2012 carries 19 gallons versus 4 gallons in the Alumacraft Trophy 185 2007. 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 Trophy 185 2007 is rated for 8 passengers, while the Alumacraft Competitor 165 CS 2012 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 185 2007 could be the deciding factor.
At this size, power-to-weight ratio matters more than outright horsepower. The Alumacraft Trophy 185 2007 comes in at 1 lbs per hp versus 1 lbs per hp for the Alumacraft Competitor 165 CS 2012. 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 185 2007 if your priority is putting more people on the water — it handles 8 passengers and at 18,0 ft it has the deck room to back that rating up comfortably. The Alumacraft Competitor 165 CS 2012 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 6 that costs less to run day-to-day.
