Alumacraft Navigator 175 Sport 2007 vs Alumacraft V-Bow 1756 AW Tunnel CC 2005 — Same Brand, Different Boat

The Alumacraft Navigator 175 Sport 2007 vs Alumacraft V-Bow 1756 AW Tunnel CC 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 Navigator 175 Sport 2007 at 17,0 ft versus Alumacraft V-Bow 1756 AW Tunnel CC 2005 at 17,0 ft. Weight tells a clearer story for trailering families: the Alumacraft Navigator 175 Sport 2007 tips the scales at 1 357 lbs — 1 271 lbs more than the Alumacraft V-Bow 1756 AW Tunnel CC 2005 at 86 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 150 hp, the Alumacraft Navigator 175 Sport 2007 has a 75-hp advantage over the Alumacraft V-Bow 1756 AW Tunnel CC 2005'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 V-Bow 1756 AW Tunnel CC 2005 carries 8 gallons versus 4 gallons in the Alumacraft Navigator 175 Sport 2007. 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 V-Bow 1756 AW Tunnel CC 2005 comes in at 1 lbs per hp versus 9 lbs per hp for the Alumacraft Navigator 175 Sport 2007. 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 Sport 2007 and its 150-hp ceiling. If fuel economy and quieter running matter more than top-end speed, the Alumacraft V-Bow 1756 AW Tunnel CC 2005 with its 75-hp rating is the more economical daily driver.

Alumacraft Navigator 175 Sport 2007 vs Alumacraft V-Bow 1756 AW Tunnel CC 2005 — Common Questions

Which is the larger boat — the Alumacraft Navigator 175 Sport 2007 or the Alumacraft V-Bow 1756 AW Tunnel CC 2005?
The Alumacraft V-Bow 1756 AW Tunnel CC 2005 is the longer of the two at 17,0 feet overall. The Alumacraft Navigator 175 Sport 2007 comes in at 17,0 feet, making it roughly 0,0 ft shorter — a meaningful difference in deck room and overall on-water presence.
Which is easier to trailer — the Alumacraft Navigator 175 Sport 2007 or the Alumacraft V-Bow 1756 AW Tunnel CC 2005?
For trailering, the Alumacraft V-Bow 1756 AW Tunnel CC 2005 has the edge at 86 lbs dry weight versus 1 357 lbs for the Alumacraft Navigator 175 Sport 2007. 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 Sport 2007 is rated to a maximum of 150 hp, giving it the larger power ceiling. The Alumacraft V-Bow 1756 AW Tunnel CC 2005 tops out at 75 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 Navigator 175 Sport 2007 is Coast Guard rated for 5 passengers, while the Alumacraft V-Bow 1756 AW Tunnel CC 2005 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 V-Bow 1756 AW Tunnel CC 2005 has a better power-to-weight ratio at 1 lbs per hp compared to 9 lbs per hp for the Alumacraft Navigator 175 Sport 2007. 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 Sport 2007 measures 95" wide, compared to 83" for the Alumacraft V-Bow 1756 AW Tunnel CC 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.
Which boat has the larger fuel tank — the Alumacraft Navigator 175 Sport 2007 or the Alumacraft V-Bow 1756 AW Tunnel CC 2005?
The Alumacraft V-Bow 1756 AW Tunnel CC 2005 has the bigger tank at 8 gallons, versus 4 gallons on the Alumacraft Navigator 175 Sport 2007. That 3-gallon difference translates to roughly 10–17 nautical miles of additional range at cruising speed, depending on motor, load, and conditions.
Are the Alumacraft Navigator 175 Sport 2007 and Alumacraft V-Bow 1756 AW Tunnel CC 2005 from the same manufacturer?
Yes — both the Alumacraft Navigator 175 Sport 2007 and the Alumacraft V-Bow 1756 AW Tunnel CC 2005 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.
