The Misty Harbor 1680FC 2012 vs Misty Harbor 1680FS 2005 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.
On paper these two are close siblings in the size department — Misty Harbor 1680FC 2012 at 16,0 ft versus Misty Harbor 1680FS 2005 at 16,0 ft. At 12 lbs and 79 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 40 hp, the Misty Harbor 1680FS 2005 has a 36-hp advantage over the Misty Harbor 1680FC 2012's 4-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load.
Both boats are rated for 8 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.
At this size, power-to-weight ratio matters more than outright horsepower. The Misty Harbor 1680FS 2005 comes in at 2 lbs per hp versus 3 lbs per hp for the Misty Harbor 1680FC 2012. 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: Performance buyers should lean toward the Misty Harbor 1680FS 2005 and its 40-hp ceiling. If fuel economy and quieter running matter more than top-end speed, the Misty Harbor 1680FC 2012 with its 4-hp rating is the more economical daily driver.
