Both the Glacier Bay 2640 Dual Console 2010 and the Glacier Bay 2665 Center Console Canyon Runner 2012 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?

The power gap is worth calling out. Rated to 300 hp, the Glacier Bay 2640 Dual Console 2010 has a 298-hp advantage over the Glacier Bay 2665 Center Console Canyon Runner 2012's 2-hp ceiling - enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Fuel capacity breaks the other way: the Glacier Bay 2640 Dual Console 2010 carries 180 gallons versus 90 gallons in the Glacier Bay 2665 Center Console Canyon Runner 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 Glacier Bay 2640 Dual Console 2010 is rated for 12 passengers, while the Glacier Bay 2665 Center Console Canyon Runner 2012 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 2640 Dual Console 2010 could be the deciding factor.
