When two boats share the same hull type — in this case both the Alumacraft Dominator 165 CS 2008 and the Alumacraft Navigator 165 CS 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 Dominator 165 CS 2008 at 16,0 ft versus Alumacraft Navigator 165 CS 2009 at 16,0 ft. Weight tells a clearer story for trailering families: the Alumacraft Dominator 165 CS 2008 tips the scales at 1 175 lbs — 210 lbs more than the Alumacraft Navigator 165 CS 2009 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 Dominator 165 CS 2008 and 90 hp for the Alumacraft Navigator 165 CS 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. Both carry nearly identical fuel loads — 2 gal and 2 gal — so range won't be a tiebreaker here.

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 Navigator 165 CS 2009 comes in at 11 lbs per hp versus 13 lbs per hp for the Alumacraft Dominator 165 CS 2008. 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.
