When two boats share the same hull type — in this case both the Glasstream 17 Bay Flite 2010 and the Glasstream 328 Pro-X 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?
Size is the most obvious dividing line here. The Glasstream 328 Pro-X 2012 measures 32,0 feet overall (2012), giving it roughly 14,8 additional feet of deck space compared to the Glasstream 17 Bay Flite 2010 at 17,3 feet (2010). At 146 lbs and 53 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 700 hp, the Glasstream 328 Pro-X 2012 has a 650-hp advantage over the Glasstream 17 Bay Flite 2010's 50-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Fuel capacity breaks the other way: the Glasstream 17 Bay Flite 2010 carries 25 gallons versus 3 gallons in the Glasstream 328 Pro-X 2012. 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 Glasstream 328 Pro-X 2012 is rated for 9 passengers, while the Glasstream 17 Bay Flite 2010 caps at 5. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Glasstream 328 Pro-X 2012 could be the deciding factor.
Bottom line: Choose the Glasstream 328 Pro-X 2012 if your priority is putting more people on the water — it handles 9 passengers and at 32,0 ft it has the deck room to back that rating up comfortably. The Glasstream 17 Bay Flite 2010 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 5 that costs less to run day-to-day.
