Alumacraft Lunker 165 CS 2011 vs Alumacraft Navigator 175 CS 2006 — Same Brand, Different Boat

Matching a deep vee Alumacraft Lunker 165 CS 2011 against a modified vee Alumacraft Navigator 175 CS 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 Lunker 165 CS 2011 at 16,5 ft versus Alumacraft Navigator 175 CS 2006 at 17,0 ft. Weight tells a clearer story for trailering families: the Alumacraft Navigator 175 CS 2006 tips the scales at 1 245 lbs — 1 171 lbs less than the Alumacraft Lunker 165 CS 2011 at 74 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 140 hp, the Alumacraft Navigator 175 CS 2006 has a 100-hp advantage over the Alumacraft Lunker 165 CS 2011's 40-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 Lunker 165 CS 2011 carries 8 gallons versus 4 gallons in the Alumacraft Navigator 175 CS 2006. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.

Both boats are rated for 5 passengers — a good fit for a family of four or five plus guests. Comfort at capacity is another matter; the longer hull typically means more seat options and better weight distribution.

At this size, power-to-weight ratio matters more than outright horsepower. The Alumacraft Lunker 165 CS 2011 comes in at 2 lbs per hp versus 9 lbs per hp for the Alumacraft Navigator 175 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: Performance buyers should lean toward the Alumacraft Navigator 175 CS 2006 and its 140-hp ceiling. If fuel economy and quieter running matter more than top-end speed, the Alumacraft Lunker 165 CS 2011 with its 40-hp rating is the more economical daily driver.

Alumacraft Lunker 165 CS 2011 vs Alumacraft Navigator 175 CS 2006 — Common Questions

Which is the larger boat — the Alumacraft Lunker 165 CS 2011 or the Alumacraft Navigator 175 CS 2006?
The Alumacraft Navigator 175 CS 2006 is the longer of the two at 17,0 feet overall. The Alumacraft Lunker 165 CS 2011 comes in at 16,5 feet, making it roughly 0,5 ft shorter — a meaningful difference in deck room and overall on-water presence.
Which is easier to trailer — the Alumacraft Lunker 165 CS 2011 or the Alumacraft Navigator 175 CS 2006?
For trailering, the Alumacraft Lunker 165 CS 2011 has the edge at 74 lbs dry weight versus 1 245 lbs for the Alumacraft Navigator 175 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 Navigator 175 CS 2006 is rated to a maximum of 140 hp, giving it the larger power ceiling. The Alumacraft Lunker 165 CS 2011 tops out at 40 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 CS 2011 is Coast Guard rated for 5 passengers, while the Alumacraft Navigator 175 CS 2006 is certified for 5. 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 CS 2011 has a better power-to-weight ratio at 2 lbs per hp compared to 9 lbs per hp for the Alumacraft Navigator 175 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 Navigator 175 CS 2006 measures 93" wide, compared to 76" for the Alumacraft Lunker 165 CS 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 Lunker 165 CS 2011 or the Alumacraft Navigator 175 CS 2006?
The Alumacraft Lunker 165 CS 2011 has the bigger tank at 8 gallons, versus 4 gallons on the Alumacraft Navigator 175 CS 2006. That 4-gallon difference translates to roughly 12–20 nautical miles of additional range at cruising speed, depending on motor, load, and conditions.
Are the Alumacraft Lunker 165 CS 2011 and Alumacraft Navigator 175 CS 2006 from the same manufacturer?
Yes — both the Alumacraft Lunker 165 CS 2011 and the Alumacraft Navigator 175 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.
