When two boats share the same hull type — in this case both the World Cat 290EC Express Cabin 2008 and the World Cat 320CC Center Console 2013 are catamaran 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?

Size is the most obvious dividing line here. The World Cat 320CC Center Console 2013 measures 32,2 feet overall (2013), giving it roughly 3,2 additional feet of deck space compared to the World Cat 290EC Express Cabin 2008 at 29,0 feet (2008). At 97 lbs and 92 lbs respectively, both sit in a similar weight class — either should pair comfortably with most mid-size SUVs and half-ton trucks, though always confirm your specific tow rating with the motor added.

The power gap is worth calling out. Rated to 600 hp, the World Cat 320CC Center Console 2013 has a 100-hp advantage over the World Cat 290EC Express Cabin 2008's 500-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Fuel capacity breaks the other way: the World Cat 290EC Express Cabin 2008 carries 25 gallons versus 3 gallons in the World Cat 320CC Center Console 2013. 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 320CC Center Console 2013 is rated for 9 passengers, while the World Cat 290EC Express Cabin 2008 caps at 8. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the World Cat 320CC Center Console 2013 could be the deciding factor.
