When two boats share the same hull type — in this case both the Glacier Bay 2690 Cuddy - Bulkhead 2010 and the Glacier Bay 3470 Cuddy 2010 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?

The Glacier Bay 2690 Cuddy - Bulkhead 2010 carries a rated maximum of 300 hp. Engine data for the Glacier Bay 3470 Cuddy 2010 wasn't available in our records — check the manufacturer's spec sheet before sizing a motor.Fuel capacity breaks the other way: the Glacier Bay 2690 Cuddy - Bulkhead 2010 carries 18 gallons versus 3 gallons in the Glacier Bay 3470 Cuddy 2010. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.

Both boats are rated for 12 passengers — a good fit for a family of four or five plus guests. Comfort at capacity is another matter; the longer hull typically means more seat options and better weight distribution.
