When two boats share the same hull type — in this case both the Crownline 320 CR 2009 and the Crownline 350 CR 2012 are modified vee designs with fiberglass 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 — Crownline 320 CR 2009 at 33,0 ft versus Crownline 350 CR 2012 at 36,0 ft. Weight tells a clearer story for trailering families: the Crownline 350 CR 2012 tips the scales at 165 lbs — 150 lbs less than the Crownline 320 CR 2009 at 15 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 — 850 hp for the Crownline 320 CR 2009 and 860 hp for the Crownline 350 CR 2012. 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 Crownline 350 CR 2012 carries 193 gallons versus 141 gallons in the Crownline 320 CR 2009. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.

Both boats are rated for 10 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.
