When two boats share the same hull type — in this case both the Glacier Bay 279 Cuddy - Bulkhead 2009 and the Glacier Bay 3480 Cuddy - Hardtop 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 3480 Cuddy - Hardtop 2011 measures 37,5 feet overall (2011), giving it roughly 9,5 additional feet of deck space compared to the Glacier Bay 279 Cuddy - Bulkhead 2009 at 28,0 feet (2009). Weight tells a clearer story for trailering families: the Glacier Bay 279 Cuddy - Bulkhead 2009 tips the scales at 1 014 lbs — 845 lbs more than the Glacier Bay 3480 Cuddy - Hardtop 2011 at 169 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.

The power gap is worth calling out. Rated to 600 hp, the Glacier Bay 3480 Cuddy - Hardtop 2011 has a 300-hp advantage over the Glacier Bay 279 Cuddy - Bulkhead 2009's 300-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 279 Cuddy - Bulkhead 2009 carries 18 gallons versus 3 gallons in the Glacier Bay 3480 Cuddy - Hardtop 2011. 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.
