Matching a modified vee Alumacraft Navigator 165 Sport 2007 against a deep vee Alumacraft Trophy 185 2010 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 Navigator 165 Sport 2007 at 16,0 ft versus Alumacraft Trophy 185 2010 at 18,7 ft. At 105 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 2010 has a 85-hp advantage over the Alumacraft Navigator 165 Sport 2007'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 Trophy 185 2010 carries 38 gallons versus 22 gallons in the Alumacraft Navigator 165 Sport 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 2010 is rated for 8 passengers, while the Alumacraft Navigator 165 Sport 2007 caps at 5. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Alumacraft Trophy 185 2010 could be the deciding factor.
