Matching a deep vee Alumacraft Classic 165 CS 2009 against a modified vee Alumacraft Tournament Pro 185 2006 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 Classic 165 CS 2009 at 16,0 ft versus Alumacraft Tournament Pro 185 2006 at 18,0 ft. Weight tells a clearer story for trailering families: the Alumacraft Tournament Pro 185 2006 tips the scales at 1 475 lbs — 580 lbs less than the Alumacraft Classic 165 CS 2009 at 895 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 100 hp, the Alumacraft Tournament Pro 185 2006 has a 25-hp advantage over the Alumacraft Classic 165 CS 2009's 75-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 Tournament Pro 185 2006 carries 41 gallons versus 2 gallons in the Alumacraft Classic 165 CS 2009. 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 Tournament Pro 185 2006 is rated for 6 passengers, while the Alumacraft Classic 165 CS 2009 caps at 5. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Alumacraft Tournament Pro 185 2006 could be the deciding factor.
At this size, power-to-weight ratio matters more than outright horsepower. The Alumacraft Classic 165 CS 2009 comes in at 12 lbs per hp versus 15 lbs per hp for the Alumacraft Tournament Pro 185 2006. 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 Tournament Pro 185 2006 if your priority is putting more people on the water — it handles 6 passengers and at 18,0 ft it has the deck room to back that rating up comfortably. The Alumacraft Classic 165 CS 2009 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 5 that costs less to run day-to-day.
