When two boats share the same hull type — in this case both the Misty Harbor 245CF 2013 and the Misty Harbor Biscayne Bay 2585CS 2010 are pontoon designs with aluminum 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 — Misty Harbor 245CF 2013 at 22,0 ft versus Misty Harbor Biscayne Bay 2585CS 2010 at 25,0 ft. Weight tells a clearer story for trailering families: the Misty Harbor Biscayne Bay 2585CS 2010 tips the scales at 232 lbs — 215 lbs less than the Misty Harbor 245CF 2013 at 17 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.
Both boats share a closely matched power ceiling — 135 hp for the Misty Harbor 245CF 2013 and 150 hp for the Misty Harbor Biscayne Bay 2585CS 2010. 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.
For family outings this is probably the sharpest distinction between the two. The Misty Harbor Biscayne Bay 2585CS 2010 is rated for 17 passengers, while the Misty Harbor 245CF 2013 caps at 12. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Misty Harbor Biscayne Bay 2585CS 2010 could be the deciding factor.
Bottom line: Choose the Misty Harbor Biscayne Bay 2585CS 2010 if your priority is putting more people on the water — it handles 17 passengers and at 25,0 ft it has the deck room to back that rating up comfortably. The Misty Harbor 245CF 2013 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 12 that costs less to run day-to-day.
