Alumacraft Lunker 165 LTD CS 2005 vs Alumacraft Tournament Pro 185 CS 2006 — Same Brand, Different Boat

The Alumacraft Lunker 165 LTD CS 2005 vs Alumacraft Tournament Pro 185 CS 2006 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 Lunker 165 LTD CS 2005 at 16,0 ft versus Alumacraft Tournament Pro 185 CS 2006 at 18,0 ft. Weight tells a clearer story for trailering families: the Alumacraft Tournament Pro 185 CS 2006 tips the scales at 151 lbs — 144 lbs less than the Alumacraft Lunker 165 LTD CS 2005 at 7 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 Pro 185 CS 2006 has a 150-hp advantage over the Alumacraft Lunker 165 LTD CS 2005's 50-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load.

For family outings this is probably the sharpest distinction between the two. The Alumacraft Tournament Pro 185 CS 2006 is rated for 6 passengers, while the Alumacraft Lunker 165 LTD CS 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 Tournament Pro 185 CS 2006 could be the deciding factor.

At this size, power-to-weight ratio matters more than outright horsepower. The Alumacraft Lunker 165 LTD CS 2005 comes in at 0 lbs per hp versus 1 lbs per hp for the Alumacraft Tournament Pro 185 CS 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 CS 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 Lunker 165 LTD CS 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.

Alumacraft Lunker 165 LTD CS 2005 vs Alumacraft Tournament Pro 185 CS 2006 — Common Questions

Which is the larger boat — the Alumacraft Lunker 165 LTD CS 2005 or the Alumacraft Tournament Pro 185 CS 2006?
The Alumacraft Tournament Pro 185 CS 2006 is the longer of the two at 18,0 feet overall. The Alumacraft Lunker 165 LTD CS 2005 comes in at 16,0 feet, making it roughly 2,0 ft shorter — a meaningful difference in deck room and overall on-water presence.
Which is easier to trailer — the Alumacraft Lunker 165 LTD CS 2005 or the Alumacraft Tournament Pro 185 CS 2006?
For trailering, the Alumacraft Lunker 165 LTD CS 2005 has the edge at 7 lbs dry weight versus 151 lbs for the Alumacraft Tournament Pro 185 CS 2006. 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 Pro 185 CS 2006 is rated to a maximum of 200 hp, giving it the larger power ceiling. The Alumacraft Lunker 165 LTD CS 2005 tops out at 50 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 Lunker 165 LTD CS 2005 is Coast Guard rated for 5 passengers, while the Alumacraft Tournament Pro 185 CS 2006 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.
Which boat has the better power-to-weight ratio?
The Alumacraft Lunker 165 LTD CS 2005 has a better power-to-weight ratio at 0 lbs per hp compared to 1 lbs per hp for the Alumacraft Tournament Pro 185 CS 2006. 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 Pro 185 CS 2006 measures 96" wide, compared to 76" for the Alumacraft Lunker 165 LTD CS 2005. 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.

Yes — both the Alumacraft Lunker 165 LTD CS 2005 and the Alumacraft Tournament Pro 185 CS 2006 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.
