When two boats share the same hull type — in this case both the Rinker 300 Express Cruiser 2008 and the Rinker 320 Express Cruiser 2009 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 — Rinker 300 Express Cruiser 2008 at 33,0 ft versus Rinker 320 Express Cruiser 2009 at 34,0 ft. Weight tells a clearer story for trailering families: the Rinker 320 Express Cruiser 2009 tips the scales at 1 236 lbs — 1 125 lbs less than the Rinker 300 Express Cruiser 2008 at 111 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.

The Rinker 300 Express Cruiser 2008 carries a rated maximum of 300 hp. Engine data for the Rinker 320 Express Cruiser 2009 wasn't available in our records — check the manufacturer's spec sheet before sizing a motor.Fuel capacity breaks the other way: the Rinker 320 Express Cruiser 2009 carries 165 gallons versus 15 gallons in the Rinker 300 Express Cruiser 2008. 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.
