When two boats share the same hull type — in this case both the Glacier Bay 2640 Dual Console 2010 and the Glacier Bay 2740 Dual 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?

Both boats share a closely matched power ceiling — 300 hp for the Glacier Bay 2640 Dual Console 2010 and 300 hp for the Glacier Bay 2740 Dual 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. Both carry nearly identical fuel loads — 18 gal and 18 gal — so range won't be a tiebreaker here.

The Glacier Bay 2640 Dual Console 2010 is rated for up to 12 people. Passenger data for the Glacier Bay 2740 Dual Console 2011 wasn't available.
