Both the World Cat 320EC Express Cabin 2009 and the World Cat 330TE Tournament Edition 2011 are catamaran designs, the first built in fibreglass and the second in composite, so 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 - World Cat 320EC Express Cabin 2009 at 32,2 ft versus World Cat 330TE Tournament Edition 2011 at 34,0 ft. Weight tells a clearer story for trailering families: the World Cat 320EC Express Cabin 2009 tips the scales at 10 900 lbs - 500 lbs more than the World Cat 330TE Tournament Edition 2011 at 10 400 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 - 700 hp for the World Cat 320EC Express Cabin 2009 and 700 hp for the World Cat 330TE Tournament Edition 2011. 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 World Cat 330TE Tournament Edition 2011 carries 300 gallons versus 260 gallons in the World Cat 320EC Express Cabin 2009. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.

For family outings this is probably the sharpest distinction between the two. The World Cat 330TE Tournament Edition 2011 is rated for 10 passengers, while the World Cat 320EC Express Cabin 2009 caps at 9. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the World Cat 330TE Tournament Edition 2011 could be the deciding factor.
