The Misty Harbor 1680FS 2009 vs Misty Harbor 2085DF 2006 comparison sits squarely in the category of decisions where specs alone won't tell the whole story — intended use, storage, and long-term ownership costs all factor in.
Size is the most obvious dividing line here. The Misty Harbor 1680FS 2009 measures 16,0 feet overall (2009), giving it roughly 14,0 additional feet of deck space compared to the Misty Harbor 2085DF 2006 at 2,0 feet (2006). At 79 lbs and 159 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.
The power gap is worth calling out. Rated to 90 hp, the Misty Harbor 2085DF 2006 has a 86-hp advantage over the Misty Harbor 1680FS 2009's 4-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 2085DF 2006 is rated for 11 passengers, while the Misty Harbor 1680FS 2009 caps at 8. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Misty Harbor 2085DF 2006 could be the deciding factor.
At this size, power-to-weight ratio matters more than outright horsepower. The Misty Harbor 2085DF 2006 comes in at 2 lbs per hp versus 20 lbs per hp for the Misty Harbor 1680FS 2009. The lower the ratio the more explosive the acceleration — meaningful on a short RIB where bursts of speed, quick planing, and agility in surf or tight waterways define the experience.
Bottom line: Choose the Misty Harbor 2085DF 2006 if your priority is putting more people on the water — it handles 11 passengers and at 2,0 ft it has the deck room to back that rating up comfortably. The Misty Harbor 1680FS 2009 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 8 that costs less to run day-to-day.
