Both the Glacier Bay 2665 Center Console Canyon Runner 2013 and the Glacier Bay 3470 Express Cruiser 2013 are catamaran 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?

Size is the most obvious dividing line here. The Glacier Bay 3470 Express Cruiser 2013 measures 37,5 feet overall (2013), giving it roughly 10,5 additional feet of deck space compared to the Glacier Bay 2665 Center Console Canyon Runner 2013 at 27,0 feet (2013). Weight tells a clearer story for trailering families: the Glacier Bay 3470 Express Cruiser 2013 tips the scales at 16 400 lbs - 10 200 lbs less than the Glacier Bay 2665 Center Console Canyon Runner 2013 at 6 200 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 - 2 hp for the Glacier Bay 2665 Center Console Canyon Runner 2013 and 2 hp for the Glacier Bay 3470 Express Cruiser 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. Fuel capacity breaks the other way: the Glacier Bay 3470 Express Cruiser 2013 carries 150 gallons versus 90 gallons in the Glacier Bay 2665 Center Console Canyon Runner 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 Glacier Bay 3470 Express Cruiser 2013 is rated for 11 passengers, while the Glacier Bay 2665 Center Console Canyon Runner 2013 caps at 8. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Glacier Bay 3470 Express Cruiser 2013 could be the deciding factor.
