When two boats share the same hull type — in this case both the Glacier Bay 2265 Center Console 2011 and the Glacier Bay 2665 Center Console 2011 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 Glacier Bay 2665 Center Console 2011 measures 28,2 feet overall (2011), giving it roughly 3,5 additional feet of deck space compared to the Glacier Bay 2265 Center Console 2011 at 24,7 feet (2011). Weight tells a clearer story for trailering families: the Glacier Bay 2665 Center Console 2011 tips the scales at 815 lbs — 749 lbs less than the Glacier Bay 2265 Center Console 2011 at 66 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 — 280 hp for the Glacier Bay 2265 Center Console 2011 and 300 hp for the Glacier Bay 2665 Center Console 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 Glacier Bay 2665 Center Console 2011 carries 18 gallons versus 12 gallons in the Glacier Bay 2265 Center Console 2011. 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 Glacier Bay 2665 Center Console 2011 is rated for 12 passengers, while the Glacier Bay 2265 Center Console 2011 caps at 1. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Glacier Bay 2665 Center Console 2011 could be the deciding factor.
