Matching a modified vee Alumacraft Navigator 165 CS 2007 against a deep vee Alumacraft Tournament Pro 185 Tiller 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 CS 2007 at 16,0 ft versus Alumacraft Tournament Pro 185 Tiller 2010 at 18,3 ft. Weight tells a clearer story for trailering families: the Alumacraft Tournament Pro 185 Tiller 2010 tips the scales at 1 385 lbs — 420 lbs less than the Alumacraft Navigator 165 CS 2007 at 965 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.
Both boats share a closely matched power ceiling — 90 hp for the Alumacraft Navigator 165 CS 2007 and 90 hp for the Alumacraft Tournament Pro 185 Tiller 2010. Real-world performance will come down more to which motor is actually bolted on, its load at the time, and whether it's a 4-stroke or 2-stroke setup. Fuel capacity breaks the other way: the Alumacraft Tournament Pro 185 Tiller 2010 carries 38 gallons versus 22 gallons in the Alumacraft Navigator 165 CS 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.
Bottom line: The Alumacraft Tournament Pro 185 Tiller 2010 at 18,3 ft is the right call if deck space, comfort, and entertaining are top of your list. The Alumacraft Navigator 165 CS 2007 at 16,0 ft wins on trailering ease, likely lower purchase price, and simpler docking — a solid choice for a buyer who wants more boat for less money.
