When two boats share the same hull type — in this case both the Misty Harbor 205CR 2013 and the Misty Harbor Grand Mistique 2585GM 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?

Size is the most obvious dividing line here. The Misty Harbor Grand Mistique 2585GM 2010 measures 25,0 feet overall (2010), giving it roughly 7,0 additional feet of deck space compared to the Misty Harbor 205CR 2013 at 18,0 feet (2013). Weight tells a clearer story for trailering families: the Misty Harbor Grand Mistique 2585GM 2010 tips the scales at 232 lbs — 219 lbs less than the Misty Harbor 205CR 2013 at 13 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 Grand Mistique 2585GM 2010 has a 75-hp advantage over the Misty Harbor 205CR 2013's 75-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 Grand Mistique 2585GM 2010 is rated for 17 passengers, while the Misty Harbor 205CR 2013 caps at 9. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Misty Harbor Grand Mistique 2585GM 2010 could be the deciding factor.

Both are 2-tube and 2-tube pontoon designs respectively. Tube diameter and gauge affect stability and load capacity — more so than most buyers realize when comparing on paper.
