Both the Glasstream 328 Pro-X 2011 and the Glasstream 328 Pro-XS 2013 are modified-V designs, both built in fibreglass, 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 - Glasstream 328 Pro-X 2011 at 32,0 ft versus Glasstream 328 Pro-XS 2013 at 32,0 ft. At 5 300 lbs and 5 300 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.
Both boats share a closely matched power ceiling - 700 hp for the Glasstream 328 Pro-X 2011 and 700 hp for the Glasstream 328 Pro-XS 2013. 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 - 300 gal and 300 gal - so range won't be a tiebreaker here.
The Glasstream 328 Pro-X 2011 is rated for up to 9 people. Passenger data for the Glasstream 328 Pro-XS 2013 wasn't available.
Bottom line: The Glasstream 328 Pro-X 2011 and Glasstream 328 Pro-XS 2013 are closely matched on the specs that matter most. Test-ride both on the water you actually use, check current dealer pricing, and factor in long-term service access before you sign.
