When two boats share the same hull type — in this case both the Alumacraft Classic 165 CS 2013 and the Alumacraft Navigator 175 Tiller 2009 are deep vee designs with aluminum construction — the buying decision usually comes down to a handful of practical questions: how many people are you putting on the water, how far do you trailer, and what does your tow vehicle weigh?
On paper these two are close siblings in the size department — Alumacraft Classic 165 CS 2013 at 16,3 ft versus Alumacraft Navigator 175 Tiller 2009 at 17,0 ft. Weight tells a clearer story for trailering families: the Alumacraft Navigator 175 Tiller 2009 tips the scales at 1 145 lbs — 250 lbs less than the Alumacraft Classic 165 CS 2013 at 895 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 — 75 hp for the Alumacraft Classic 165 CS 2013 and 75 hp for the Alumacraft Navigator 175 Tiller 2009. 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 Navigator 175 Tiller 2009 carries 38 gallons versus 17 gallons in the Alumacraft Classic 165 CS 2013. 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 Classic 165 CS 2013 comes in at 12 lbs per hp versus 15 lbs per hp for the Alumacraft Navigator 175 Tiller 2009. 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: The Alumacraft Classic 165 CS 2013 and Alumacraft Navigator 175 Tiller 2009 are closely matched on the specs that matter most. Test-ride both on the water you actually use, check current dealer pricing, and factor in long-term service access before you sign.
