Both the Misty Harbor 2080EF 2009 and the Misty Harbor 2085CP 2009 are pontoon designs, both built in aluminium, so 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 2080EF 2009 at 20,0 ft versus Misty Harbor 2085CP 2009 at 20,0 ft. At 1 480 lbs and 1 460 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 - 90 hp for the Misty Harbor 2080EF 2009 and 90 hp for the Misty Harbor 2085CP 2009. 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 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.
Bottom line: The Misty Harbor 2080EF 2009 and Misty Harbor 2085CP 2009 are closely matched on the specs that matter most. Test-ride both on the water you actually use, check current dealer pricing, and factor in long-term service access before you sign.
