When two boats share the same hull type — in this case both the Glacier Bay 3470 Express Cruiser 2013 and the Glacier Bay 3480 Hardtop Ocean Runner 2013 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?

On paper these two are close siblings in the size department — Glacier Bay 3470 Express Cruiser 2013 at 37,5 ft versus Glacier Bay 3480 Hardtop Ocean Runner 2013 at 37,5 ft. At 164 lbs and 169 lbs respectively, both sit in a similar weight class — either should pair comfortably with most mid-size SUVs and half-ton trucks, though always confirm your specific tow rating with the motor added.

Both boats share a closely matched power ceiling — 2 hp for the Glacier Bay 3470 Express Cruiser 2013 and 2 hp for the Glacier Bay 3480 Hardtop Ocean Runner 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. Both carry nearly identical fuel loads — 15 gal and 15 gal — so range won't be a tiebreaker here.

Both boats are rated for 11 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.
