When two boats share the same hull type — in this case both the Misty Harbor 2585CS 2013 and the Misty Harbor 2585GM 2009 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 2585CS 2013 at 25,0 ft versus Misty Harbor 2585GM 2009 at 25,0 ft. Weight tells a clearer story for trailering families: the Misty Harbor 2585GM 2009 tips the scales at 232 lbs — 210 lbs less than the Misty Harbor 2585CS 2013 at 22 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 150 hp, the Misty Harbor 2585CS 2013 has a 135-hp advantage over the Misty Harbor 2585GM 2009's 15-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load.
For family outings this is probably the sharpest distinction between the two. The Misty Harbor 2585GM 2009 is rated for 17 passengers, while the Misty Harbor 2585CS 2013 caps at 15. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Misty Harbor 2585GM 2009 could be the deciding factor.
Bottom line: Choose the Misty Harbor 2585GM 2009 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 2585CS 2013 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 15 that costs less to run day-to-day.
